• Measure side clearance of inner gear and outer gear in at least
four places around each outside edge. Clearances measured val-
ues should be within the specified clearance.
• If clearance is less than standard, select inner gear and outer gear
as a set so that clearance is within specifications. Refer to “Parts
Information” for the inner gear and outer gear selection.
• If clearance is more than standard, replace whole oil pump assem-
bly except oil pump cover.
• Measure clearance between outer gear and oil pump housing.
• If not within allowable limit, replace whole oil pump assembly
except oil pump cover.
Seal Ring Clearance
• Measure clearance between seal ring and ring groove.
• If not within allowable limit, replace oil pump cover assembly.
