Check outer (1) and inner rotors (2), rotor plate, and oil pump
case for excessive wear or damage.
Check relief valve (1) for excessive wear or damage and
operates smoothly.
MEASUREMENT
Radial clearance
Check radial clearance between outer rotor (1) and case (2),
using thickness gauge (3).
If clearance exceeds its limit, replace outer rotor or case.
Limit on radial clearance between outer rotor and case for
oil pump
0.310 mm (0.0122 in.)
Side clearance
Using straight edge (1) and thickness gauge (2), measure side
clearance.
Limit on side clearance for oil pump inner rotor
0.15 mm (0.0059 in.)
