The crankshaft converts the reciprocating motion of the pistons into rotation and carries that power to the flywheel and driven equipment, supported along its length by bearings that depend on a pressurised oil film. This group covers perkins crankshafts, main and connecting rod bearings, thrust washers, connecting rods, flywheels and ring gears, dampers and timing gears. Perkins publishes regrind limits and undersize bearing grades across its ranges, so a worn crankshaft is often machined and returned to service. On generating sets the flywheel and coupling arrangement connects the engine to the alternator, and misalignment there transmits loads into the crankshaft and rear main bearing that the engine was not designed to carry.

Misalignment between engine and alternator transmits bending loads into the crankshaft and rear main bearing. It is a common cause of repeat rear bearing failure.
Usually yes, if it is within the published regrind limits and free of cracks. Matching undersize bearing shells are fitted afterwards.
Visible distortion, fluid leakage on a viscous damper, or a shifted index mark. A failed damper allows torsional vibration to reach the crankshaft.
