Crankshaft: Testing and Inspection
Cleaning and Inspection
CLEANING
CAUTION: Handle the crankshaft with care to avoid possible damage to the finished surfaces.
Clean the crankshaft with solvent, then blow out all oil passages with compressed air.
INSPECTION
Measure the diameter of each journal in at least four places to determine an out-of-round, taper or undersize condition.
On an engine with a manual transmission, check the fit of the pilot bearing in the bore of the crankshaft. A needle roller bearing and adapter assembly
is used as a pilot bearing. it is press fit directly into the engine crankshaft and should not be loose. inspect the inner surface of the pilot bearing for
wear or a bell-mouth condition. Check the inside diameter of the pilot bearing to see if it is worn or damaged. The bearing and adapter assembly
cannot be serviced separately. The pilot bearing can only be installed with the seal end of the bearing facing the transmission. The bearing and seal are
pregreased and do not require additional lubrication.
NOTE: A new bearing must be installed whenever a bearing is removed.
Inspect the pilot bearing, when used, for roughness, evidence of overheating or loss of lubricant. Replace if any of these conditions are found.
