Inspection
PULLEY AND PULLEY SHAFT
+If pulley is cracked or deformed, replace it.
+If ¯uid leak is found around the pulley shaft, replace the oil seal.
Disassembly
CAUTION:
+Parts which can be disassembled are strictly limited. Never
disassemble parts other than those speci®ed.
+Disassemble in as clean a place as possible.
+Clean your hands before disassembly.
+Do not use rags; use nylon cloths or paper towels.
+When disassembling and reassembling, do not let foreign
matter enter or contact the parts.
+Remove snap ring, then draw drive shaft out.
+Be careful not to drop drive shaft.
+Remove oil seal.
+Be careful not to damage front housing.
+Remove connector.
+Be careful not to drop control valve.

Assembly
Assemble oil pump, noting the following instructions.
+Make sure O-rings and oil seal are properly installed.
+Always install new O-rings and oil seal.
+Be careful of oil seal direction.
+Cam ring, rotor and vanes must be replaced as a set if neces-
sary.
+When assembling, coat each part with ATF.
+Pay attention to the direction of rotor.
+When assembling vanes to rotor, rounded surfaces of vanes
must face cam ring side.
+Insert pin
V2into pin grooveV1of front housing and front side
plate. Then install cam ring
V3as shown at left.
