See sig for model. I am having major trouble getting the center bolt out of the harmonic balancer (one that bolts into the crank). I even sprayed some lube on it and let it sit a few days. I even snapped off one of the two threaded puller inserts on the harmonic balancer while I had something wedged in there to keep the engine from rotating. I don't see any place on the flywheel to keep the engine from rotating. Is there some access place and a tool for this? I also thought about trying to use an impact gun but there is no clearance to get the tool in there. I doubt even removing the radiator would give me enough room. Any suggestions?
