Translate that into clockwise or counter-clockwise facing the bolt, and do you know for sure.

Well I found the special Honda/Acura 50mm crank pulley tool at Pep Boys for $40, so we'll give it another go next Saturday, out of time for today.

COUNTER clockwise looking at it like a regular bolt.

Excellent, that's what we were trying (crank spins clockwise normally, looking at the bolt). Oh man, I got to wait another week...

Check this, I bent the 50mm tool trying to loosen the crankshaft bolt the "proper" way:

Foiled again, the car was lifting up via the 50mm + breaker bar. Plus I bent the pin in the breaker bar. The 50mm tool is pretty damn thick. That's one mean bolt.

:mad:

Holy crap!!

Are you are trying it with a warm/hot engine? :confused:

First I tried cold last weekend with impact and lousy breaker bar setup. This weekend I warmed up the engine to 202F and let it sit there for a while at 202F (fan kicks on at 204F), then hit the bolt with both impact gun and proper breaker bar + 50mm setup. The crank bolt was too hot to hold onto, so it was decently warm.

Next weekend I will try heating the bolt directly with a small propane torch or some such. After that, car shop!

DUDE i just hit mine with my craftsman 350lb torque impact wrench in my garage. Took 3 seconds 2 come loose. I didn't even use a tool to hold the crank, just hit the crank bolt with a stong impact gun.
