Side clearances
IMeasure side clearances between end of oil pump housing and
cam ring, rotor, vanes and control piston. Measure in at least
four places along their circumferences. Maximum measured
values should be within specified positions.
IBefore measurement, check that friction rings, O-ring, con-
trol piston side seals and cam ring spring are removed.
Standard clearance (Cam ring, rotor, vanes and con-
trol piston):
Refer to SDS, AT-199.
IIf not within standard clearance, replace oil pump assembly
except oil pump cover assembly.
Seal ring clearance
IMeasure clearance between seal ring and ring groove.
Standard clearance:
0.10 - 0.25 mm (0.0039 - 0.0098 in)
Wear limit:
0.25 mm (0.0098 in)
IIf not within wear limit, replace oil pump cover assembly.
ASSEMBLY
1. Drive oil seal into oil pump housing.
IApply ATF to outer periphery and lip surface.
2. Install cam ring in oil pump housing by the following steps.
a. Install side seal on control piston.
IPay attention to its direction Ð Black surface goes toward
