17 Chevy Cruze
ugh.... i just remembered i should of done this before i yanked my building motor....
I'm just trying to get a feel for the situation and this may be a stupid question but is the compressor your using big enough for a 3/4" impact wrench?Well now that we have a problem... i borrowed a 3/4 inch drive impact gun (1200ftlbs) from Monroe and it still won't come off..... great i am shit out of luck
I'm just trying to get a feel for the situation and this may be a stupid question but is the compressor your using big enough for a 3/4" impact wrench?
1200 ft/lbs is almost 10 times the recommended torque setting for the bolt. Even torquing to 300 or 400 ft/lbs requires a ridiculously long handle on the wrench or a torque multiplier on most cases. It can't be that tight.
Well it sounds like the compressor is adequate...
The only other thing I can think to do is apply heat, but that is not without it's own pitfalls. Heating up the bolt could transfer heat to the crankshaft possibly harming the front seal and of course the timing belt would most certainly have to be removed as well.
The thing is even if you over-torqued it with a 1/2 impact wrench I would think the 3/4 wrench should still pull it off.
Even without re-coating the threads with motor oil before re-installing the bolt I would also there was enough residual oil to prevent the bolt from seizing. Odd.
Was there rust on the bolt or pulley last time the bolt was removed?
Oh so no residual oil then? That could be the problem. It says explicitly in my FSM to oil the threads before installing the bolt. Subaru must have it's reason's for that.The bolt was brand new from Subaru. The Shortblock had 0 miles from Ron over at axis performance. This thing is a head scrarcher.
Picture of That ?This method doesn't work if you don't have a stock crank pulley.
The easiest way I know and am comfortable doing it is by sticking a medium screwdriver in the HOLE PROVIDED in the trans bellhousing. It's right below the dowel pins.
1. Insert screwdriver
2. 22mm socket on long breaker bar
2a. Wiggle crank to ensure screwdriver has engaged the ring gear on the flywheel
3. Pull from the passenger side gently until screwdriver has positively locked the motor still.
4. loosen crank bolt.
