5VZ Clutch Job

Ok guys, this won't be the most thorough of write ups, but hopefully it'll help some of yall. First things first, this was on a supercharged 03 5VZ w/ about 125K miles on it. The clutch was in terrible condition, you literally could not drive it easy enough and the clutch not slip, even at 45mph... just barely feathering the gas and it almost redlines. This is my sisters ex-bf's truck and it's been pretty well taken care of... other than all the mud on the under carriage from deer camp. I tried to take as many pics as possible, but eventually you're covered in dirt and not in the mood to fuck w/ a digi-cam.

Here's the culprit/victim
Image

Image


The truck almost didn't fit in the garage due to having an ARB and me having a junk desk that takes up too much damn room.
Image

Image

That woulda been bad b/c all my tools are in the garage. It just barely fit.

First things first, gotta start w/ taking the shifters out.
Image

The shifter balls just screw onto the shifters, any retard can figure that out. Once you remove those, you've got 4 small screws to remove on the shifter cover, 2 at the front and 2 that connect it to the center console.
Image


Once you've got the shifter cover off, you've got the rubber shifter boots and retainer plate to remove, you've got 4 screws there... Then boom, you see the top of the transmission and transfer case.
Image

Image

On the transmission shifter, the retainer plate is held down by 2 tabs and it's spring loaded... so you have to push down the retainer and turn it counter clockwise and the shifter will come loose. I didn't get a pic of this, b/c I felt like it was pretty self explanatory.

The transfercase shifter, always shift into 4Hi when removing this. However, this is held in place by a snap ring so you'll need snap ring pliers to get it out and back in. Be careful though, b/c you don't wanna lose this.
Image


Once you have both shifters out, inspect the shifter bushings, most of the time, the bushing that the shifter sits in is gonna basically separate once you pull it out. You can go back w/ stock or you can hit up Marlin Crawler for these:
Image

and these:
Image


See what I mean by caked under carriage???
Image

To avoid this any shit dropping in your eye, pressure was the under carriage before you start any work. Dirt does hide on top of the transmission and transfer case, however.

First, go ahead and hit your driveshaft bolts w/ some pb-blaster(especially if it's friday night and you're gonna start this on a Saturday). Break all the drive shaft bolts loose, and get those outta the way.

Go ahead and disconnect your slave cylinder from the bellhousing, so you don't kink any of the hard lines up once the transmission tilts down.
You're gonna wanna remove the starter bolts before any bellhousing bolts, just to keep things in order. I highly recommend using a ziploc baggie system w/ a sharpie to label all the bolts as to not get any mixed up. You can remove all the bellhousing bolts w/o removing the crossmember, except for the top bolts. B/c the transmission is gonna have to lean down in order to really get to the top bellhousing bolts. You're gonna need several extensions and swivels(aka u-joints) in order to access the upper bolts. I used all hand tools on this project b/c my impact gun doesn't supply enough torque to really break those bolts loose.

You're gonna have a few sensors to disconnect on the transmission and transfercase before you can pull it out. You've got the speedo signal sensor(or cable on older model Tacoma's that don't use a digital speedo), the reverse light sensor(passenger side of the transmission, 2 wire connector), 4WD gauge light sensor(on the passenger side of the transfercase)... then last but certainly not least, the first o2 sensor. I'm gonna go ahead and tell you, that thing is a BITCH! The bracket is bolted to the top of the transmission w/ one of the bolts that holds the tailshaft housing to the transmission case, so the bolt is long as shit and you have ZERO room to really work. You'll get 1/4 turns each time, pretty much, very frustrating. You might be able to just unhook the sensor, but this truck was very caked and I could make heads or tails of how to disconnect the sensor w/ only feeling w/ my hands and not being able to put my eyes on it. The whole wiring harness really needs to be unclipped from the transmission, and be prepared to break a couple of those clips. There's not enough slack in harness for it to hang and get tangled up on anything though if you do break some clips.

Now comes the fun part, and I HIGHLY recommend either renting or purchasing a transmission jack. Northwestern tools(along w/ many others) make adapters for regular floor jacks to utilize them as a transmission jack, but either way, it's nice to have something to chain the transmission down w/ so it doesn't start to roll on you once you start pulling it out. I ran into some trouble w/ the front drive shaft and I couldn't get it disconnected at the flange, so I had to let it slip apart. There's really not much room to work on that either b/c the rack and pinion gets in the way real quick. When I dropped the trans, it nailed the lines going to the rack and pinion, but luckily, just a little cosmetic damage, nothing major.
Image


This is the stock pressure plate still in place...
Image


This throwout bearing was BAD BAD BAD off... it was literally almost seized up.
Image


Anyone notice any hot spots? HA!
Image

Image


This is the stock clutch, it was worn down to the rivets and completely glazed over. This is bad.
Image

Image


While you're doing a clutch job, it's ALWAYS ALWAYS ALWAYS a good idea to replace this little fella...
Image

The flywheel has to come off to get resurfaced, and you're right there at it, and these trucks are notorious for leaking at the rear main once the miles start racking up. Plus, the seals are like $8, so it's cheap insurance. Why have to basically redo all this work a couple months down the road for just once little round seal??? I'm not gonna go into great detail how to do this, b/c if you've gotten this far, you can figure out how to do this little chore.

I took the flywheel to a local machine shop to have it resurfaced, this is the 2nd flywheel they've done for me, but they've done other work for me... top notch stuff and the guy knows his shit about anything that has an internal combustion engine.
Here's the pretty newly resurfaced flywheel...
Image


That was the last pic I took b/c I was tired of fucking w/ it and I wanted to get done, so the rest of this will be all text.

Most pilot bearing pullers that you can rent at the parts store are too big to fit in a Tacoma pilot bearing. If you take this project on yourself, the best way to get it out is w/ a blind hole puller from autozone. It's a lot like a pilot bearing puller, but the tip is smaller and it'll go in the pilot bearing. You can then tighten it to adjust it, and it'll widen while it's in the pilot bearing, grabbing a hold of it. Then you just use the slide hammer to yank it out.
Here's a pic of one to help you get an idea if you don't know what it looks like.
Image



I then put the flywheel back on and torqued the bolts down to 63 ft-lbs as recommended. USE LOCTITE!!!! I can't emphasize this enough. You're gonna have to wedge something between the frame and the flywheel to hold it still while you torque on it... or put a death grip on it w/ your other hand and torque it. This method is a bitch.

After you've got the flywheel torqued down, break out your new clutch set and start reassembling and make sure you have your clutch facing the correct way, put your clutch alignment tool in the splines of the clutch disc, then put the pressure plate on the pegs and hold all this w/ your hand while you start the bolts for the pressure plate on the flywheel. Begin tightening down the pressure plate and making sure you keep the disc lined up using the alignment tool. Torque the pressure plate down to 14 ft-lbs.

Clean your bellhousing out w/ some brake cleaner to get all the clutch disc dust out. Take some good grease and grease the pivot ball for the clutch fork, then put a little light coat on the fork where the throwout bearing rests and hook all that up. One rookie mistake that anyone can make is not allowing the clutch fork to come out far enough. If you do this, it won't allow the slave cylinder to line up correctly w/ the dimple in the clutch fork. This could spell a quick death for your slave cylinder, as the piston isn't going straight and it'll ruin the seal b/c it's rubbing on the seal at an awkward angle.
Once you've got your throwout bearing and clutch fork in place, everything else is basically the reverse order. You're gonna wanna get the transmission jacked up and in place, and you might have to spin the rear driveshaft flange to line up the splines. BUT, typically you can get it on the first try. Then just get your bellhousing bolts started, and once you've got it up there, again, check your clutch fork to make sure you've got it out far enough for the slave cylinder to mate up good. After you've done everything in the reverse order, you're just about done.

You can use a power bleeder for the last step or you can use a friend to do the old fashion clutch bleed. I used my power bleeder, but I didn't feel like I was getting that firm of a pedal on it. For those of you that don't know how to bleed a clutch, it's real simple. Make sure the clutch master cylinder reservoir is full, then have a friend pump the pedal about 9 or 10 times and then hold it to the floor. You're gonna get under the truck and crack the bleeder valve(just a little though) to let the air bubbles out. Then snug the bleeder back up. Have your buddy pump the pedal and hold it again to let more out. You're gonna keep doing this until you get a firm pedal feel. Typically after 3 or 4 times of this, you'll get a good feel.

Some people go ahead and replace the clutch hydraulics w/ a new clutch, as like the rear main seal, it's just cheap insurance. If you do this, you're probably gonna have to adjust the pedal throw.

If anyone has any questions about any of this, feel free to ask. If I left a step out, I'm sure it'll come to me. Hopefully this can be added as a sticky and it'll help some of you guys in the future.

I forgot to list the tools needed to do this...
a good socket set;deep and shallow sockets(12mm, 14mm, 15mm, 16mm, and 17mm)
At least 2 or 3 feet of extensions
2 swivels at best
End wrenches(8mm, 10mm, 12mm, 14mm, and 15mm)
Snap wring pliers
Safety glasses(gotta protect those eyes)
Phillips head screw driver
A couple of big fat heavy duty flat head screw drivers(to help seperate the bellhousing from the engine if necessary)
Floor jack or transmission jack
A friend to pull and put the transmission back in if you're just using a regular floor jack
It's been a while since I've done this job, so I can't remember every tool needed.
 
#3 ·
Ive been meaning to do this too. I'll see if i have any pictures than can help. biggest problem I ran into was lack of extensions.. you need a lottt. another thing is having small hands.. my hands had a really hard time getting to the top of the bell housing for those bolts.

Also- make sure to reattach all the plugs for the transmission, transfercase, and all that other stuff before it's bolted back on.. it's a pain to do afterwards ;)

list of tools i didn't see you mention: torque wrench for flywheel bolts and gasket maker.

back of the engine and the bearing that needs to be pulled/replaced

old on the left and new on the right, I let my clutch go so long that it wouldnt grip anything. I was stranded and had to get AAA to bring me to my house at 4am

And a list of all the various links I used at the time to research

I've found that this jack works much better for pulling trannies on out trucks. May not work well for a car because it may not fit under, but for a truck it's awesome. Just jack up to it, block as needed, and remove the bolts. Drop at will and wheel away. 500 lb capacity, so no worries.

It was a complete lifesaver when doing my crawl box, and I couldn't imagine doing it without it...

Good timing Wes!! LOL....Don't get mad when I blow up your phone all day Saturday..LOL! (j/k)
So I guess I'm missing a rear main seal, the shifter seals, gasket maker (the orange/gray shit in a tube right?), and pilot bearing puller. Or do the grease trick.
Any other seals or preventive crap to do besides the rear main while I have everything out? I like the idea of fixing shit BEFORE I get stranded in BFE.....LOL....
eta - I've been thinking of replacing the slave...it has 150K on it.
The clutch master has already been replaced within 40K.
 
#9 ·
Trevor, definitely gonna wanna replace your shifter bushings. The one that the shifter sits on doesn't have to be removed, so you can go ahead and order them from marlin and just install em when you get em. I would definitely replace the slave, its only a matter of time if its got 150k on it. Call me if you need me.
 
#18 ·
uhhh opps. i think i just put regular grease on mine when i did mine 2 yrs ago. that might make it fun next time around
 
#7 ·
you can use wet newspaper and a socket extension instead of the bearing puller... works like a champ, and less messy than the grease method.
 
#8 ·
The transfercase shifter, always shift into 4Hi when removing this. However, this is held in place by a snap ring so you'll need snap ring pliers to get it out and back in. Be careful though, b/c you don't wanna lose this.
Image
Nice writeup dude.

But FWIW I used a pair of needle nose pliers for the Tcase "snap ring"


and Doug, I tried that newspaper trick, ended up pushing the PB in more. Then destroyed it and only had the outter race left. Thank god the slide hammer did the trick :)

You must have been hitting the bearing then. it takes some time, but you fill the area behind the bearing with the wet newspaper and never touch the bearing itself. Has always worked like a champ for me.

I guess I'll replace the slave as well.
So on the shifter seats - I want the white one right? for a 3.4 5vz 5spd 4x4 -
It's a R150F top shift right?
Thanks!

Okay....so thought I'd post a few things to add to this great little thread. These are a few things that I had trouble with....which will hopefully help someone else out in the future.
A buddy and I started on this yesterday morning. I'd highly recommend a buddy...LOL....they don't have to be mechanically inclined, just the extra hand helps. Everything went fine, besides a few stupid hick-ups.
Front/Rear driveshafts came out fine, starter unbolted fine, got hung-up on pulling the shifters for a minute. When you pull the shifter-boot cover off, you will want to take a couple screwdrivers, (we use punches) and push down on each side of the metal thing that the spring seats to. Then twist and pull the shifter out. We also got hung up for a while trying to figure out what Chilton meant when they said "remove the rear end plate by removing the nuts and 2 bolts". Well guess what, Chilton is fucking stupid and cost me 1hr's time. LOL...This is where I called Wes. Thanks Wes!!!
So the "rear end plate" that Chilton was referring to - its 4 bolts, NOT 2! and NO nuts! Stupid fuckers. This is why I like TTORA writeups.
Next lesson learned,
*DO NOT* use 3/8ths extensions on the bellhousing bolts.
We didn't have long enough extensions (even though I knew I was supposed to have them) so I did a mix of 3/8's" and 1/2" extensions.
Yea - well when I was working on one of the bellhousing bolts - the 3/8's Craftsman swivel Blew up on me! My fucking pinky finger smashed into the tranny when it gave way! :mad:
Image

Then I had to wait until today to purchase 3 feet of 1/2inch extensions.
Harbor Freight has a "quick release extension bar set" for $20. I picked up one of these, along with some black-impact extensions. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?function=Search
Image


Here is a picture of the Bellhousing bolt hole (bolt removed) where you need the super-long extension. Your 1/2" extensions will extend from this hole (middle of the picture) all the way past the Tcase. You need to drop the tranny down a little to access it. This picture was taken from under the drivers seat - that's the entire length of tranny and tcase.
Image


Next up was disconnecting all the wires to the tranny. This little job sounds easy, but it fucking sucks!!
Here is a pic of where I used a socket, on a swivel, accessing the 14mm bolt from inside the cab. I figured this out after trying to fuck with it for 30 minutes from under the truck. There are wires attached to a mount, held on by this bolt.
Image


I also screwed up and strapped the tranny to the tranny jack with the straps OVER the wiring. You can NOT do this. LOL....run your straps under all of the wiring.

Today I did the remaining work by myself. (actually removing the tranny).
I don't see how anyone could do this without a tranny jack. Being able to jack up, and drop-down with such precision was killer. I now know why Wes did a little bit of carnage to the lines coming off of the rack. :D
If I was using my Craftsman floor-jack, my shit would be fucked.
It's a tight fit to move the tranny in-between the rack lines, and the ear on the exhaust (that the tranny-mount bolts to on the exaust pipe). I did a lot of maneuvering, and finally wiggled it out. :D ahhh....what a good feeling. :D
Image


I have to find a local machine shop tomorrow to resurface the flywheel:
Image


Here is what is left of my clutch. I don't know if it's good or bad...LOL...
Image


I also checked the price on the blind-hole puller Wes referred to at Autozone. They wanted $140!!!!!!
I picked this one up from Harbor Freight on sale for $32.00
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=95987
I'm going to see how it works tomorrow.

I'm going to search for a OEM clutch slave, then order some parts from Marlin.....and once all that stuff shows up, put everything back together.
 
#25 ·
QUESTIONS - Should I replace my steering rack - since it looks super easy to get to, and I need to anyways? I have a spare one with new bushings sitting in the garage? :confused:
ALSO: The rear main seal - what do you use to tap that back in? My manual says SST only....(fuck that) and I definitely don't have a socket that big....LOL....
okay, back OT....
Okay, few more pics. Keep in mind this isn't my D.D.....(for now)..so the reason it is taking forever - is because I could care less if it sits for a bit.....LOL...
Picked up a new clutch-slave from T.G. (yea, yea - it was better than e-bay).
They got it to me in like - 3 days. I was really impressed.
Marlin is sending me the shifter-bushings, haven't received those yet.....
Image


Here is the old "Release" or T.O. bearing....It was fucked!!! It reminded me of my old 1" skateboard wheels that sounded like gravel rattling around in a tin-can.
Image

Here is the HF cheapo Blind-Hole Puller - that worked great! :D Picture was right after I pulled the pilot bearing...
Image

HF blind hole puller:
Image

That is where I ended tonight (very short)- because I forgot to order my Rear MainSeal......(I was even at Toyota today for the new Taco). Fuck!!!! :D
 
#26 ·
I saw no mention of this seal thing (pic below)? Please don't tell me this is something I have to order from Toyota.......

Also - which way does the clutch go on? Fat side with the most springs towards the engine or trans??

Also - greasing the throwout bearing - I know to grease the parts where the clutchfork touch, but what about the inside? Or the mouth? I'm not sure what exactly to grease there??

My chilton manual is a useless POS.


Image
 
#27 ·
No one????? :confused:




So, I guessed that the larger portion of the clutch disc goes on the flywheel side......hopefully someone can chime in before tomorrow when I have to bolt this bitch up????:confused:

I guessed on greasing the throwout bearing....I greased the inside very lightly where it rides on the input shaft.........I greased the input shaft what I think was very lightly....."very lightly" is hard to determine over the intranet.....maybe someone can chime in on the pics. I greased the outter portion (obvious) where the clutch fork arms sit.....then greased the inside of the clutch fork where the ball sits, and the ball itself....hope I didn't miss something.

I also used red loctite on the flywheel bolts, and the clutch cover bolts.
Use the loctite sparingly, as mine seeped out of the bolt holes, and onto the flywheel. :(

I still don't know what to do about that stupid piece of rubber/gasket thing in the above pic. :confused:

I feel like I've been talking to myself here....
greased shaft:

greased splines:

Flathead craftsman normal screwdriver fit perfect and held the flywheel for torquing:

#28 ·
that almost just looks like grease crud.... i dont remember there being any seal on my inspection plate?
 
#29 ·
Hey Trevor,
sorry, I've been MIA today. I can call you tomorrow if I don't make myself clear on here. As far as the shit build up on the inspection plate, just clean it off and bolt it back on once you get the transmission back in. I think it's a combo of clutch dust and some kinda foam isolater they put there from the factory.

From what I can tell on your input shaft splines, they look good on the greasing. I use just enough to give it a little sheen/shine. Your clutch, if I'm understanding you correctly, you're asking if the side that sticks out more goes towards the flywheel/engine side of things??? Yes. The "flat" side goes towards the transmission. The bad thing is, I've seen some aftermarket clutches where both sides are damn near the same and it's very confusing. The best thing to do is pay close attention to what side the flat side is on when you pull it out. Again, the flat side should be up against the pressure plate when you pull it off. BTW, my slave on my 4Runner came off eBay and I paid $15 ;). It's Aisin as well. That's neither here nor there at this point.

Excellent idea on the screw driver into the flywheel tooth deal. My hands were fucking KILLING me after torquing all those flywheel bolts down. Talk about a bitch. I couldn't come up w/ anything in my head that would work well. Kudos to you for coming up w/ that. Sad thing is, I carry that same flathead in my 05' Tacoma in my tool kit, but I don't have 1 in my tool chest in the garage. HA! I'll be up for a while, so if you're still working on it and you've got more questions, just give me a shout. If you need me tomorrow, I've got physical therapy from 2pm-3ish and then I have a night class at 6-9... up until those 2 time periods I'll be sitting on my ass :D.

Oh yeah, and if you've got a good rack to replace yours, shit... go for it. I could be wrong about this, but you'll probably need a front end alignment after you change em' out though.
 
#53 ·

Another method is to slip a punch through one of the holes circled below it will hold the flywheel in place hands free while torquing. A punch with a diameter closest to the diameter of the holes is best and with as short of handle as possible to keep it from getting in the way while you are wrenching.

#30 ·
Thanks Wes!! Yea, my main concern was that foam thing....but since it's no biggie - I'll just bolt everything up tomorrow.
Yea, that aftermarket one from gripforce was much thinner than my OEM. I was able to tell though, and bolted it up correctly - so that's good to hear. :)
I did pick-up a clutch slave from Trailgear, and marlin finally sent the shifter bushings. :)

I was going to swap in the spare rack (that's what took so long) but after inspection - it needed new TREs...so tacotoy on here sent me new ones - I went to install, and noticed my rack was leaking! So I'm scrapping that idea and I'll deal with the rack later.
I gotta get this thing back on the road tomorrow - since the 06 DD blew another CV boot.....
Thanks for the help Wes!!
Trevor
 
#31 ·
LOL damn man... 1 bad thing after another huh? Oh yeah I forgot, as far as the rear main seal, just put the plate the broad side of a 2x4 and use a mallet to just tap the seal into the plate.
 
#34 ·
Tell me about it!! Man....not a good past few months with me and autos....


Thanks ShowStop - I didn't use very much, so I will throw some more on there right now. I took off early from work to get this thing put together tonight.

The grease trick with the throwout bearing does seem like it would work good. I just figured sometime in my lifetime, I could use the blind-hole puller again - so I picked one up. It was cheap.

On the rear main seal - oh man, I forgot about that. I thing I used too much gray RTV.....It speewed out the sides. I forgot to get you guys' input on that....pics below....:(
 
#32 ·
The direction the springs on the clutch disc face depends on the engine type. V6 = springs toward flywheel
2.7L = springs toward pressure plate

Nice job with the screwdriver trick. I do the same thing. Works like a charm. Everything else looked good so far. I couldn't tell for sure, but make sure you have a decent amount of grease on the fork ends where the TO bearing pivots on the fork.
 
#33 ·
anyone use the grease trick to get the pilot bearing out? its free and takes about 2 minutes. i just use a bolt from the bell housing and fill the backside of the bearing with grease and tap the bolt in the center and it popes right out.

Flat piece of wood and BFH to tap back in (make sure to tap evenly):

The part I am unsure of - amount of RTV I applied:

I made the mistake of not torquing this down with a torque wrench either. I just hand-tightened, and may have tightened too much since the RTV speewed out the side.

I also RTV'd the bottom - but didn't get a pic. And also RTV'd the corners of the oil pan area real good.

Sounds good. The bolts are only 9 ft-lbs torque, so good-n-tight with a wrench should have been fine. The RTV pushed out is a good sign. Did you swipe the inside of the seal with some GP grease before you installed?
