Scrape the sealant from the front gear cover and gear housing surface, for front gear train engines, or the
cylinder block, for rear gear train engines.
Use solvent or steam to clean the front gear cover.
Dry the cover with compressed air.
Inspect the gear cover for cracks or damage.
Replace the front gear cover if any damage is found.

Use solvent to clean the oil and seal residue from the crankshaft surface.
Dry with compressed air.
Inspect the nose of the crankshaft for excessive wear.
Lip style front crankshaft seal:
NOTE: If the crankshaft has excessive wear, a service wear sleeve is available for engines that use a lip style
front crankshaft seal.
For engines equipped with a lip style front crankshaft seal, inspect the crankshaft seal contact area for a wear groove.
If the groove is deeper than 0.25 mm [0.01 0 in], a wear sleeve and oversize seal must be used. Refer to Procedure 001-025 in Section 1.
Non-lip style front crankshaft seal:
For engines equipped with a non-lip style front crankshaft seal, use a fine crocus cloth to remove any nicks or burrs.
There is no wear sleeve available if the crankshaft nose sealing surface is damaged.
