crank pulley threads

[EBirck]

I am replacing the timing belt on my 99 trooper. I am having trouble with loosening the bolt holding the crank pulley on. I wanted to make sure that it uses a standard thread and that I'm not muscling it the wrong way. I assume that it is turned counter clockwise, same as any other bolt would be to loosen. Any thoughts? I also must go and purchase a jig to hold that sucker still. The transmission doesn't engage enough to hold it while weilding the breaker bar. Any thoughts would be appreciated.
Thanks

I just order the parts to do my 99 also, but haven't started the job yet. There is another member on this board that rebuilt his engine an hopefully will have the answer. I believe he said some of the pullys didn't need to come off to remove the belt? Also, make sure you replace the water pump and belt tensioner pushrod while you have it opened up.

Easy.

Put bar and socket on crank bolt.

Rest bar on chassis rail...make sure no wires in the way.

Crank the engine....the bolt will undo.

The tricky part...especially if you have an automatic....is getting the crank bolt retightened after you switch the cam belt.

There is nothing to lever on to tension up.

The way i do it is to put socket on bolt and sharply hit bar with a hammer. If the crank bolt is not done up real tight the key way on the crank and pulley will rapidly wear...and the pulley will vibrate.

Hi...just had words with my mechanic friend. He says leave the big bolt alone and undo the 4 small ones and pull the pulley off that way.

You have to take the whole crank pulley off on the 3.2/3.5's for a T-belt R&R. Like 2dogs says, use a breaker bar and the starter-bump trick. Pull the fuel pump relay first (safety first! ). Snug the bolt and give it a good wrap with a mallet to tighten when you are done. The 'ideal' way to remove and replace the crank pulley bolt is with a ballzee impact gun, but you usually need to remove the radiator and all for clearance first.

i have a 93 trooper 3.2. I used a breaker bar and a 1 1/2" diameter pipe. I put the breaker bar inside the pipe about 2 feet length, put it on 5th gear and pull with slow force so the bolt wont break and it lossened no problem.
