Thank you very much,

Otherwise the shaft may be displaced a bit towards the backplate, and/or the rear race may not be correctly seated in the crankcase. While the rod/piston/liner is out, gently heat the engine up to just under 100 degrees C and tap the crankshaft forward sharply a few times. I have made a brass punch to do this. One end has a step machined in it and the smaller end just fits into the induction hole. Reassemble and check the crankpin clearance.
