Crank Pully Removal help Please

88crx SI... tring to get the SOB off to replace timing belt/head removal. Anyone have any hint, tips or tricks? Thanks in advance

Well, the easiest way is with a big air gun, but if you don't have that, you have to lock up the flywheel with something and then use like a 2ft breaker bar. I've gotten them off that way as well.

I tried the impact at 150psi with the flywheel locked in place... just pounds away but doesn't come undone. Hopefully I'll get it eventually.

Spray it with PB Blaster. You must have a shitty ass impact wrench, at a 150psi it should about brake the crank in half.

It's a Husky Brand impact. Sprayed it with PB Blaster earlier. I'll keep spraying it all night and hit it in the morning. Still got the truck to drive around in to no real hurry on the repair. Sucks, this is the only bolt holding me back. Already got both manifolds loose.

I have an air gun with 500ft lbs of torque, it takes them right off. If you have the flyheel locked, get a breaker bar.

I take that back 4G4D. I had a bolt on the crank pully i wedged that held it till I put the 3' cheater pipe on it and bent the bolt.
What the best/ easiest way to lock up the flywheel?

I took off the flywheel guard plate under the engine and wedged something in the gears, once locked I was able to break the bolt free.

You can also remove the starter to access it too.

Yeah that works great, till you shear off the gears.

Sparsky, just cut the bull crap. just buy the ZC already. you are wasting money on a motor that your not even going to keep. Just buy the ZC and let me have your old motor....and seats.
oh and take out the a/c already it doesn't even work!!!

^done it plenty of times,works fine!

I barrowed my friends Impact 500ft/lb max and his 1/2" air hose and it didn't budge. I have the pully tied down to the frame of the car. I'm wondering if that's the problem. Do I need it so the pully will spin, but not the crank it's self? With the Pully tied off I've already cracked 1 socket and 2 extensions, and warped the shit outta my 3/8" breaker bar. I now have a 3/4" drive breaker bar and socket along with a 6' water pipe. I'll wait till further word before I use it.
What could I be doing wrong?

Just wonderin... It's not a reverse thread correct?
Also, might it be possable to just slip the belt off the cam, redo the head and some how manage to slip the belt back on?

This 1 bolt Is kickin my Ass.

Wow - you've got a stubborn bolt. Hmmm, having the pulley tied down to the car shouldn't make any difference. If you've got the flywheel locked, you should be able to break that bolt off with a breaker bar. I would use anything less than a 1/2in socket though - cause you'll snap them off all day long. I'd give it another try with the new one.

ehh.. I figure if it snaps the 3/4" drive socket, it's time for a new motor. LOL. This is gunna be the last ditch effort.

Try turning it the other direction.

I've tried that with the impact, but not with the breaker bar yet.

okay i have the same problem, flywheel is locked, its on an engine stand and i can't get that fuckin crank bolt to move.??? ne one know what i can try??

(i have tried impact and breaker bar)

Well I finally got the mo'fo. Had to use the 3/4" drive w/ 6' cheater pipe. Tried doing it with out the pipe but damn near busted a nut. Hell even with the pipe it took alot of force. Nearest I can tell they used a Yellow substance on the bolt. I'm assuming some off brand of loc-tite.

It is a regular thread BTW. Jeff I suggest you get you at least a good set of 1/2" drive sockets, extension and breaker bar, Your gunna need it.

Oh, and thanks for all the help guys.

how do u lock the flywheel and or the pulley so u can turn the bolt? mine was locked but came loose from the impact wrench. ( keep in mind my engine is on a stand)

mine was a standard 88 CRX SI. All I did to lock the pully was grab one of my cargo straps from my truck. Put one hook in one hole, wraped once on the lower controll arm then hooked the 2nd hook on another hole in the pully. Figured if I F'ed up the pully (which I didn't) they're cheaper than a flywheel. Held great BTW.

flywheel is locked now i can't move the bolt, me and my friend put like 300lbs of pressure on the damn thing and it would not turn. yes im turning it the right way too. ne one know what to do??

I had a hell of a time with mine. Breaker bars and lesser impact wrenches wouldn't budge it. I ended up buying an Ingersoll Rand rattle gun that puts out something like 600 ft-lb in reverse. It took it right off. I will never buy a cheap impact wrench again.

i've tried electric impact wrench, it was fail, just about broke the socket is all, didn't even turn the bolt. im gonna try to get air supply and a air impact see if i can't break that sum bitch loose!

Jeff, you know what hell I had to go through. My issue was they put thread lock on it. Sounds like they did the same to you. See if you can't find anyone with a 3/4" drive socket, extension and breaker bar. Then aquire a good 6' piece of pipe. That's the only advice I can give ya.

You might be able to get it with a good set of 1/2" drive stuff, just make sure it's of Impact quality.

thats funny, you know i had the same prob with the hub bolts on my 88 civic, i had my 300 lb friend stand on my braker bar and he broke the bar. so one side i cut is in half and it broke free, but the i went out and got a 1/2 gun with 400fb and the other side came right off.

you can try to heat it up a little, but not to much.

have you ever used the starter for dampner bolt removal?

what do you mean? like lock (hold it still somehow) a ratchet on the bolt then crank to motor over?

while the engine is installed in vehicle, use 1/2" breaker bar and impact socket with a bar against lower part of vehicle (frame),
then crank the starter, it should knock the bolt loose.

wonder if theres any chance of breaking a tooth off the flywheel doing it that way. pretty creative though

I'll bet that doesn't work AND might ruin the starter.
