Side clearances
+Measure 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 mea-
sured values should be within specified positions.
+Before measurement, check that friction rings, O-ring,
control piston side seals and cam ring spring are
removed.
Standard clearance (Cam ring, rotor, vanes and
control piston):
Refer to SDS, AT-1210.
+If not within standard clearance, replace oil pump assembly
except oil pump cover assembly.
Seal ring clearance
+Measure 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)
+If not within wear limit, replace oil pump cover assembly.
ASSEMBLY
1. Drive oil seal into oil pump housing.
+Apply 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.
+Pay attention to its direction Ð Black surface goes
toward control piston.
+Apply petroleum jelly to side seal.
b. Install control piston on oil pump.
