Re: Connecting Rod Bearing ~ Torque Specs
The bearing wears on the upper shell, as it does, it doesn't push the piston up as high. the ridge forms slowly and if the ridge is large enough, the new bearing puts the upper position higher and the top ring hits it. If it's large enough in both parts, that's what happens. Have you ever tried pushing a piston rod assy out without reaming the ridge? I've seen guys break a piston land too.
