I'm having a belt/ water pump job done on my 86 na and have just been informed by my mech that he cannot get the bolt off the end of the crankshaft. He's done all he can to get it off and is afraid if he uses any more force he will damage the motor. Any ideas here? I'm in Florida and the car is in Indiana so this is driving me crazy! Anyone had this problem before? How did you solve it?

Flywheel lock, PB Blaster, and long breaker bar (3')

The mechanic is telling me he's used a 4' bar as well as an impact wrench and nothing will budge it, what kind of damage could he do trying too hard? This is starting to **** me off, I already bought a new water pump and now he's saying " let's just wait on the pump and I'll just do the belts" WTF! I want my new pump installed while he's in there!

Tell him to grow stronger.

So as long as the flywheel is locked he can't do any damage regardless of how aggressive he gets with a breaker bar? He seems scared he's going to damage my motor which in turn has me pretty tweaked out.

Does he have the correct factory flywheel lock in place? It seems to me he might be scared if he is using another method to lock the flywheel. He cannot damage anything if that lock is in place. As for the water pump, tell him if he chooses not to fit it he must do the job again for free if it fails before the belts.

Usual for shops that offer to work on our cars without any real knowledge, you have to pay for his 944 education.

Advise the mechanic to use the starter. Often it's the initial "snap" that is needed.

Who's the mechanic? 3/4 inch impact and more pressure should do the trick.

get a bigger impact wrench

or try using the 'fire wrench'

Just a thought, does he know it's lefty loosey? Some crank bolts are non-standard threads and if he has limited experience he might think that is the case with the 944.

Also, make sure that bolt goes on with 150lbft otherwise you will not have oil pressure.

Tell the mechanic to get a man to break it loose...

If a flywheel lock is installed there is little to no risk of damage to the motor! The lock secures the flywheel bolted to one end of the crankshaft, the bolt he is trying to break loose is in the other end of the crankshaft! nothing but a beefy crank in between!

Tell him to quit being a pansy and remove the bolt already!

PorscheDoc

How are you guys getting a 1/2" or 3/4" impact in there without removing the radiator, lol?

Big breaker bar, flywheel lock, and a man like Jkoawoody is all that is needed. The breaker bar is going to break before the bolt snaps

The mechanic is a friend of a friend, he's not a Porsche mech but restores triumph tr-2/3/6/7s professionally and seems very capable. I'm not sure if he has a factory flywheel lock tool or if he's rigged something, where would I acquire this tool and what would be the cost? This may be why he's afraid to push it too hard with a breaker.

The starter motor works great to break it loose but you need a proper flywheel lock to retorque it.
