1988 toyota pickup- HELP!

[brushogger]

I have a 1988 4wd pickup with a 1984 22r carb engine in it. I need to install a timing chain, but can't remove the crankshaft bolt that holds the pulley and balancer on. Is this bolt a reverse thread? My manual doesn't say. I don't have an impact wrench, and I just broke my 1/2" breakover trying to get this @#$%^&* out. Any Ideas? Thanks for any help/

Take a good quality six point socket and 1/2" breaker bar (high quality) and place it on the bolt with the handle against the frame. Then disconnect the coil and bump the starter with the key. Works like a charm........just make sure you put the handle on the correct side (forget which at the moment and don't want to think but take a min. and you'll figure it out) and just barely bump the starter.

Thanks for the tip! Was the bolt a normal right hand thread though?

Duhhhhhhh! I guess it would be if the cranking action of the motor would loosen it. I get brain farts working after midnight. Thanks again!

You stand a good chance of breaking the starter housing or worse doing this.

use a good breaker bar or an impact wrench.

Don't underestimate the value of a good breaker bar. I snapped a half inch Crapsman then watched a fried go after the same bolt with his three eights Snap-on. The bar bent but the bolt broke loose.

Very interested in hearing the outcome of the motor crank method if you did it.

i used the starter to break the bolt loose on the crank when i changed my timing chain this winter. mine was a 22r-e, but i assume the crank bolts are the same (right hand threads). the handle of the breaker bar sits in a notch created by the steering box on top of the driver's side frame. take off the coil wire and just bumped it. the bolt broke loose then i unscrewed it the rest of the way with my fingers.

it is kinda scary to try but worked like a charm. good luck.

I've done this many, many times to many different models with no ill effects. The starter turns the engine on such a low gear reduction that I can't see it ever breaking from the tiny bit of resistance the bolt offers when it's broken loose.

I'm at my wits end. I tried the starter trick and it didn't break loose. I put it in 4 hi 5th gear and chocked the wheels. Bought a good breakover with an impact socket and used a 2 foot cheater. Still won't come apart. I'm afraid to heat it but don't want to destroy the balancer. Any more ideas?

I now have it tied off with approximately 400 lb feet of torque sitting on it and have been tapping on it with a hammer after soaking it with PB Blaster. Still hasn't budged.

[brushogger]

Tried fire and ice on the bolt. Still no go. A friend of mine has a 3/4" impact he said I could use. He guarantees it will come out or it will snap it off. I hate to risk that. I'd really be up the creek then. I'm still open to any ideas. I have it still sittinf with about 400 lb feet of torque on it and soaked with PB. I'm hoping it breaks loose during the night, but it's doubtful.:mad:

on my 22R, I did the breakerbar against the frame trick - two blips of the starter and it was loose.

King Kong must have torqued that on for you previously :(

[brushogger]

Finally beat that $&@"? bad boy. 3 different nights I heated it red hot let the glow die, and hit it with a 3/4 impact @ 140psi. Today it came out and the threads were perfect. I don't understand but I'm happy. :wings:

That bolt is a pain for sure. I could never get it without the starter bump method.

congrats on getting the bugger to budge, I'm sure the victory beer tasted sweet

Toyota must like playing this game with their crank bolts - on my wife's is300 the starter trick didn't get it off either, I broke a 1/2" drive breaker bar and my giant 1/2" ratchet before my roomie got back and found another breaker bar for me to have a go at it with. An hour and many curses later I knew for a fact that my kung fu was better
