98 Sub OB 2.5 crank bolt removal direction

Featured Replies

Just verifying the crank pully bolt removal thread direction. I would assume the direction is a CCW to remove, I don't want to assume though.

 

On my 1st car some bone head broke the bolt off and cracked the pully. To sell the car he rewelded the pully back on. after 2 days of driving the weld broke and I needed a new engine.

It's standard threads.

 

If you don't have the correct harmonic balancer tool you can cheat by putting your breaker bar over by the battery tray and hitting the key to get it loose.

 

Of course then you gotta worry about how to torgue the thing tight when re-installing.

Hi Dave,

 

I have the engine out on a stand. Just got back from town (again) to pick up a 22mm 1/2" deep socket. I was told by a mechanic that he uses an impact wrench and they come right off.

If you're lucky. I've taken to trying them while still on the car. So that I can use the breaker bar trick if necessary.

 

I recently broke down and purchased the IR 2131QT 1/2" impact that was on sale at Sears for 149. They had been going for 120 or so USED on Ebay. My main reason for getting it was that it has 600 ft/lb in reverse. Occasionally none of my 3 impacts will remove that bolt so I had to go borrow someone else's gun. I don't like to borrow tools.

 

Good luck with the removel - but yea - standard threads.

 

I have trouble with about 1 in 10 it seems.

PB Blaster, impact wrench, and it comes right off. If not, jam the flex plate/flywheel in place and use a Craftsman 1/2' breaker bar and a big pipe. . . . :lol:

The bolt came off using the 22mm with a 1/2" drive and a 3/4" x 2' blk pipe cheeter bar. The pully came off by rocking it by hand (I was lucky).

Well done.

 

I usually smack the pulley (after the bolt has been removed) from a few different directions with a rubber mallet. Then it's just wiggling.
