Doing my belts

Hey guys, I started the job of doing my belts and waterpump lastnight, and I ran into a problem today. I am trying to remove the 24mm crankshaft bolt and it is absolutely stuck. I already broke one wrench and bent another about 30 degrees! I think with the breaker bar setup I am using, there is probably about 250-300 lbs of torque. So I am starting to think that something might be wrong here.

I searched and saw some other ppl had problems with this also (i.e. Overkill etc.). Someone said that they made it so that the breaker bar touched the ground and cranked the car over to loosen it I don't think I will be trying this method, but what should I do? Look for a bigger breaker bar, spray the crap out of it with liquid wrench, etc?

Thanks,
Nate

Soak it down overnight in PB blaster or liquid wrench. I had the same problem with mine, I ended up shattering an impact socket before I finally got it off. I assume that you have a flywheel lock in place to hold the motor since you managed to break a few wrenches already? If not get one and I would highly advise against cranking the motor to break the bolt loose, that is just asking for trouble.

Yeah I have a flywheel lock in place. I think I am going to just keep spraying it with liquid wrench and hope for the best. Has anyone had any luck with heat?

do you really need to remove the bolt? you can get the belt out with the bolt\pully in place.

Yeah I guess it is not absolutely necessary, so should i just leave it on and carefully install the camshaft and balanceshaft belts starting with the gears held on by the crankshaft bolt?

I've never removed the crank pulley to install belts. Never removed the other pulleys to put a water pump on either.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

IIRC you have to remove the rear half of the timing belt cover to access the WP. In order to do that you have to remove all the pulleys on the front side of the lower half of the engine.

i missed the minor detail of changing the water pump...
never changed the water pump but if you cant get the bolt out without doing some damage' like breaking the head off, try to get the pump out leaving the pulley in place and pulling the cover out to gain access, maybe remove all that you can and then try it. if you cant get it then get the bolt out.

1) Flywheel lock (Yes, I noticed you have one.

2) Car on wheels on level surface.

3) Socket and large breaker bar (1/2 inch drive, 24 inch long necessary)

4) Floor Jack on end of breaker bar to compound leverage.

If this doesn't work you may have a bolt and crankshaft with damaged threads... BTDT

OK guys, the soaking overnight in liquid wrench did nothing. Do you guys think I will be able to bend the back cover enough to get the water pump out? The wrench that I have bent back and forth a few times now is a 24" 1/2" drive breaker bar with a 1/2" diameter shaft I attached a 5 ft metal tube to it for extra torque, which just ended up bending the wrench without budging the bolt (I dont even want to know how much torque I was getting out of this setup) So I dont know if putting the car back on the ground and using a floor jack is a worthwhile idea, since my wrench can't take any more load anyhow.

I just finished getting the balance belt, camshaft belt and all the rollers off the car (except for the gears on the crankshaft bolt of course ) By bending the plastic back cover a little I can definately access all the bolts on the top of the water pump, but the 3 on the bottom are definately going to be a problem. I will let you guys know if it is possible to do the waterpump without removing the back belt cover soon. Hopefully I have some good luck here

So it is possible just takes a little too much effort. The 3 bolts on the bottom side of the water pump are definately a pain, and it is hard to manuever the pump out of there. The back cover plate will slide over the camshaft belt gear on the crankshaft bolt giving about 4 inches to work with on the water pump. Its not easy to work with, and I would defiantely recommend removing the crankshaft bolt and gears if possible to get the water pump out.

Time to get her back together now. Thanks for the help guys.
Nate

The only problem with doing it this way is when the crank seal starts leaking..and it will, you will actually have to remove the pulley. So if you are doing the water pump, and usually the engine will also need balance belt seals (which means removing the front housings too so the o-ring can be replaced) the pulley still has to come off.
I would do it now as you will end up doing it later anyway.

Britwrench - You got it out there before I could....I was just thinking the same thing.

Nate-
Britwrench makes a good point here, if you had any oil in your belt covers, you'll want to get those bal shaft and crank seals....which will require that crank bolt to come out. That's pretty crazy though, 5-feet of leverage and still bending tools!!! If you didn't have any oil in your belt covers, you may be able to get away without doing your seals for a little while but like Brit pointed out, sooner or later, you'll have to get that bolt off.

I've used heat, with great success, to remove stuck threads, (never had a prob with the crank bolt though). It's definately worth a try. Hopefully the prob isn't damaged threads.

good luck!
