I have a 2003 Tacoma 2.7 liter. I have 3 drive belt pulleys on the crankshaft. The most rear one had the harmonic balancer built into it. The pulley part of it came off and broke loose. I have to get the crankshaft pulley bolt out. Mine has an automatic transmission so I cant put it in gear and break the bolt loose with a breaker bar. I have to do it different. I am thinking of doing the breaker bar thing where I put a braker bar on it and then resting the end of the bar on my frame and then bump the starter. Any of you guys confirm that this works ? If so tell me more about it. Plus I would like to know if the first two pulleys come off without having to take the crankshaft bolt out ? I did take out the 4 small bolts. Any help is really appreciated .

Shut the engine off with it in drive and do it just as you would with a manual in gear and the E-brake on and wheels chocked.

You can use a chain wrench around the pulley & a big breaker bar. Just remember, once that crank bolt has been taken off, it MUST be replaced w/ a new bolt.

Why a new bolt ?

Why a new bolt ?
It's a fine pitched thread & it stretches. Trust me on this, it's cheap insurance. My 96' Tacoma's 3RZ shit the bed after I had the front main replaced. It was torqued properly & backed out about a wk later. The HB backed off the oil pump & toasted my pistons.

Does anyone know if the other two pulleys in front of the rear one will come off while the crankshaft bolt is still in place ? I have taken off the 4 small bolts and the two front pulleys are still tight on there and won't come loose

Ok I just the crankshaft bolt and puleyy off . Thank God ! I can barely see the woodruff key or whatever you call that half moon key or pin . It look great but I'm scared if I take it out I may not get the new one in. It way far back in that hole . Is it used to drive anything else other than the pulley ?

Do you guys think I should replace the crankshaft seal while I am there ? They are only $8 and doesn't look too hard to replace . I think they just press inward with a large socket and a hammer .

You aren't gonna disturb the key. The other pulleys can remain bolted to the crank pulley, it'll all come off as 1 unit. I'd just replace the seal & the bolt... both are cheap insurance & you're already that far along.

I'm going to bet in your case the bolt didn't get torqued correctly. I'm running on 100k+ miles on my current engine after I swapped the crank pulley. No issues with the bolt backing off.

Ok , I just got my crankshaft pulley holder made. When I was buying the bolts , I was at a specialty store that handle only bolts and fasteners. The guy asked me how much torque I was gonna use. I said between 193 and 217 Ft. Lbs . He said that was way too much. I said that was what is needed. I even went by Toyota and they showed 193 Ft. Lbs on the 2.7 which is my engine , and 217 Ft Lbs on the 3.4 V-6 . The bolt guy said that would break the bolt. He said that only around 50 lbs or so was only needed and that I got Ft Lbs and inch Lbs mixed up. WOW . I just smiled and said thanks and went on.

You'll probably bend those bolts in the process, but hopefully the tool will hold up.

Best not to take advice from that hardware guy. He doesn't have a clue what he is talking about. :eek:
The bolts are the hardest and highest rated ones so they should be good. I made this based on a friends tool he made. The bolts are M8X1.25 Class 10.9 . They are strong .

He probably meant 50 ft lbs on those bolts...
