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 mWM crankshafts, main and connecting rod bearings, thrust washers, connecting rods, flywheels and ring gears, dampers and timing gears. TCG engines in CHP and biogas service run continuously at constant speed and high load, often approaching 80,000 operating hours before major overhaul. That duty is steady rather than cyclic, which suits plain bearings well, but it means bearings accumulate an enormous number of revolutions and depend absolutely on consistent oil condition and pressure across the whole interval.

MWM quotes intervals approaching 80,000 operating hours to major overhaul on some TCG models, subject to fuel quality and maintenance regime.
Bearings accumulate an enormous number of revolutions between overhauls with no rest periods. Oil analysis at scheduled intervals is the main tool for detecting developing wear.
Where the shaft is within published limits and crack-free, machining and matching undersize bearings is the normal route. Measurement against MWM's limits determines this.
