NEED HELP: HOW DO YOU REMOVE THE CRANK SHAFT PULLE

[knightowl99]

I am changing my timing belt. I tried using my electric impact gun (330 lb ft) and the bolt would not come loose.

How much power is needed to remove the crank shaft pulley bolt?

How big of an air tank and how powerful of an air impact wrench is needed to loosen the bolt? How many psi or lb ft is needed?

I've never been down there yet on the Integra, but on other cars, some times it is opposite threaded bolts.
Check the manual..

The impact should work.

I don't believe that you need to remove the crank pulley, rather it's easier to remove the other belts, then remove the engine mount and slide the timing belt off that way.

Remember to change the water pump and tensioner.

DON'T TRY THAT TRICK WITH THE STARTER MOTOR!!!

Unless you switch the wires on the starter motor, you will only TIGHTEN the nut on the crank pulley.

I know of two methods to do this:

1) (worked for me) Put a standard 1/2" drive socket wrench on the nut. Ratchet it towards the front of the car (so the wrench has the most possible distance to turn the nut counter clockwise). While someone in the car puts it in 5th gear (or Park) and steps on the brakes, lie on your back under the car with your feet pointing towards the rear of the car. Put on work gloves, grab the backside of the the bumper (or whatever else is handy) and leg press the wrench. The engine allows a bit of flex before you'll really be putting a lot of force on the nut.
Keep on pressing/bouncing/kicking. Mine came off this way with not much drama.

2) Use a lot of extensions to get the socket wrench clear of the fender. Support the extension near the wrench with a floor jack. Put a big ass pipe on the wrench and muscle away.

Good luck,

Holden's way has worked for me, but only when the clutch doesn't slip. I've been successful with the air impact wrench plumbed directly to the compressor, with as few restrictive connections as possible.

Holden: did that exact method you posted on an 89 Integ but, i used a chain pipe to hold the crank and a 3/4" breaker bar to break it loose. The "kicking" method caused the car to lift off the jackstands and this is NOT the safest or correct way to do this job! that's why i purchased the electric impact hoping that i could break the crank bolt free.

Blownaway: what size impact wrench you use? and how many H.P./gal. size is your air compressor?? that you used inorder to break this bolt free?

anyone try/use a 3/4" air impact wrench? brand & cost?

any suggestions or thoughts would be appreciated as i am stuck until i can find a powerful enough air setup...HELP!

thanks.

Does anyone not understand. You DON'T have to remove the crank pulley to change the timing belt.

Where the engnie and tranny bolt together underneath the engine, there is a cover plate that if removed allows access to the flywheel. Use a large screwdriver or a prybar to wedge the flywheel just be easy on the teeth. I used an old floor jack handle as a breaker bar with 1/2 ratchet. Reguires some elbow grease but cheaper than a impact wrench. You'll need sm\ome where in the neighborhood of 600lbs to get the sucker off.
Lungren, isn't the plastic cover piece held on behind the crank pulley? On 90-93 Itegra's, the crank pulley must me removed to remove the cover piece to get to the timing belt. I have a 90, just did a timing belt on a 93. Both required removal.

I'm not sure if the cover is held in place by the crank pulley, no. That would really suck.
