Water pump bearing and sealsInspect the camshaft for damage to the journals and the lobes. Inspect the following components for signs of wear and/or for signs of scuffing:
camshaft bearings
camshaft followersInspect the crankshaft for any of the following conditions:
deflection
damage to the journals
bearing material that has seized to the journalsCheck the journal taper and the profile of the crankshaft journals. Check these components by interpreting the wear patterns on the following components:
rod bearing
main bearingsNote: If the crankshaft or the camshaft are removed for any reason, use the magnetic particle inspection process to check for cracks.Replace the crankshaft vibration damper if any of the following conditions occur:
Engine failure due to a broken crankshaft
Excessive wear of the front bearing for the crankshaft
Excessive wear of the gear train that is not caused by a lack of lubricationInspect the gears of the gear train and inspect the gear train bushings for the following conditions:
Worn gear teeth
Unusual fit
Unusual wearCleaning and Inspection of Components
