Subsection 07 (LUBRICATION SYSTEM)
If difference exceeds service limit, replace the
complete oil pump assembly.
NOTE: When the axial clearance of the oil pump
shaft assembly increases, the oil pressure de-
creases (less discharge).
Check the inside of oil pump housing and crank-
case area for scoring or other damages. If so,
change the complete oil pump assembly.
NOTE: If the surface only shows a small groove,
use a grindstone to burnish burrs.
When the oil pump is seized, replace crankcase
assembly and complete oil pump.
