Post which direction to loosen crankshaft pulley bolt?

Hey everyone,

I've been trying to replace the water pump in my '99 GSI and i've got up to the taking the crankshaft pulley off but this bolt is a bitch to get off.

I was just wondering which way i'm meant to be turning it to loosen it because i've been turning to the left so far and i've broken two of my sockets on the bolt.

is this the right way to loosen it?

cheers,
Sam.

Use an air impact wrench on that one. Crank your pressure all the way up. That is one of the toughest bolts to loosen. Not sure which direction, 95% sure its not reverse threaded.

yeah i've been trying to get in contact with my mate who has an impact gun, but i don't want to use that much torque and find i'm tightening it and mess up the bolt/crank pulley.

You might try some PB Blaster on the bolt, this will help loosen it up. I didn't need to use an impact gun and simply used a 1/2" inch breaker bar (about 2.5 feet long) and my foot.

I've broken sockets on the crank bolt before too. It happens.


Sockets, ratchets, you name it!

I use a 1/2" 19mm impact socket, a long extension, and a 2 ft breaker bar with a 4 foot cheater pipe over the breaker bar. I have one of the hex shaped pully holder tools on another breaker bar the end of which is on the garage floor to keep it in place. I find that bouncing on the cheater pipe/breaker bar helps to break it loose. I'm amazed that I haven't broken the extension or breaker bar (yet) with how much it bends.

Be aware that the bolt will break free with a snap and you don't want to go flying when it does.

I've tried impact wrenches, but I think you need a monster one to get it off.

I used the starter method when I did the timing belt on my '95. Something I learned working on my Toyota 4x4's.

Absolutely 100% sure. I busted a 19mm socket on it too.

Impact sockets have fared better IME.

MAKE SURE you're using a 6 point socket. 12 pt sockets will flex and slip. Impact sockets are great. I don't have an impact, but have invested in certain size impact sockets.

It is a normal thread. Extentions, etc CAN hinder you in getting adequate torque. You should've seen me under the car with a 1/2" breaker bar, hands on the top side of the bumper support and pushing on the breaker bar with my feet. It was a bitch! I didn't have the extensions I needed to be able to stand up and break it loose with the breaker & cheater.

FWIW, this seemed like it took a LOT more torque than the axle nuts. Those things are no problem for me.
