I am working on a Briggs & Stratton model 12H802-2390-B1. It had a bent crankshaft that made the engine vibrate pretty bad so I figured since I had a spare crankshaft, I would just swap it out. I got the new crank in but when I tightened the connecting rod cap down, it was so tight, that I couldn't turn the engine by hand. So if figured maybe the new crank had a different size journal. I put the bent crank back in and when tightened down, it also made the engine too hard to turn. What is going on here? I tried tightening the rod cap bolts to 100 in lbs per the repair manual and made sure to oil the journal and rod before assembling. The cap only fits one way so it is not backwards. Before I tightened the rod cap for the first time, I did it by hand (without the torque wrench) so is it possible I screwed up the rod so it is too tight now?
