Maintenance & Replacement
During an overhaul, magnitude-flux and measure the journals for taper, ovality and bearing clearance; grind or replace when dimensions fall outside factory limits. Early signs it may need attention: A deep knocking that gets louder under load usually indicates a worn or spun main bearing; Low oil pressure at hot idle can follow insufficient journal clearance; Excessive end float shows as an audible clunk when the clutch or torque converter engages.

Work on a clean machine with the engine off and the relevant system drained or depressurised as required, and confirm the part number against your machine model and serial number before ordering. Pair it with correctly-sized bearings and clean, present oil galleries. After installation, run the machine and check for leaks, unusual noise or abnormal travel before returning it to service, and retighten where the manual calls for it after the first hours of operation.
