Harmonic balancer question
I was timing my engine and I had the breaker bar and socket on the harmonic bolt to set it to TDC. My helper bumped the motor and the breaker bar loosened the bolt. I don't know if the balancer rotated on the shaft or not. I tightened it back up as much as I could by holding the pulley. I went ahead and went through the normal process to time it and it seems to be running fine and no codes. Not sure but I think I hear a slight lifter noise which was previously not heard. I would assume I need to torque the bolt and I don't have the torque specs. Also is there anything I can check to see if the balancer is if fact not rotated affecting my timing? Any help would be appreciated. Thanks Sandy

Really glad to hear that. I don't have room to look up in there. Any info on torque specs? Thanks for your help. Sandy
Is it referred to as the crankshaft bolt in the manuals?

70-90 ft.lb. keep an eye out for oil leak(sling out around crank pulley) depending on how loose it got, instructions say to smear a blob(small), of RTV on end of crank shaft, where woodruff key slot is, before putting bolt in and tightening, supposed to help keep oil oozing out slot.

I wouldn’t worry about that. The balancer is pressed on. It wouldn’t have backed out just by loosening the bolt. I’d just tighten it back up.

The only other time I'd seen it, I thought it was somebody's hack fix.
I didn't seal mine when rebuilt a few years back, but so far so good.
