1) Check the seal ring and oil seal for breaks or
damages.
2) Check other parts for dents or abnormalities.
3) Selection of oil pump rotor assembly
(1) Tip clearance
Install the inner rotor and outer rotor to oil pump
housing. With rotor gears facing each other,
measure the crest-to-crest clearance.
Tip clearance:
0.02 — 0.15 mm (0.0008 — 0.0059 in)
(2) Side clearance

measure the oil pump housing-to-rotor clear-
ance.
Side clearance:
0.02 — 0.045 mm (0.0008 — 0.0018 in)
(3) If the depth and/or side clearance are not
within the specification, replace the rotor assem-
bly.
Measure the total end play and adjust it within
specification. <Ref. to 5AT-105, ADJUSTMENT,
AT Main Case.>
