NOTE:
When installing oil seal (1), press-fit it till its end face is flush
with oil pump case (2) end face.
Check outer and inner rotors, rotor plate, and oil pump case for
excessive wear or damage.
MEASUREMENT

thickness gauge.
If clearance exceeds its limit, replace outer rotor or case.
Limit on radial clearance between outer rotor and case:
0.200 mm (0.079 in.)
Side clearance
Using straight edge and thickness gauge, measure side clear-
ance.
Limit on side clearance: 0.10 mm (0.0039 in.)
ASSEMBLY
