Measuring Outer Rotor to Pump Body
1. Outer Rotor
2. Pump Body
3. Feeler Gauge
3. Place outer rotor in pump body and check
clearance by inserting a feeler gauge be-
tween the rotor and body. Check to a max
of 0.022 in (0.55mm}, Figure 63. If ex-
ceeded a new pump is required.
NOTE: If not to specification replace the oil
pump, as reduced pump pressure through
wear could result in reduced engine life.
Installation
1. Clean and coat parts in new engine oil.
Place outer rotor in pump body and en-
sure free rotation. Insert inner rotor and
pump plate assembly into the body and
ensure that shaft is fully seated into bush-
ing.
2. Assemble the front plate to the body using
3 or 4 bolts and torque to 17-21 lbf ft
(23.0-28.4Nm) 2.3-2.9 kgf m.
NOTE: After tightening ensure the drive gear
rotates freely by hand at least 5 revolutions, if
not "disassemble" and repeat the exercise.
