(6) Oil Pump

Correcting Cylinder (Oversize)
1. When the cylinder is worn beyond the allowable limit, bore and
hone it to the specified dimension.
Cylinder I.D. (Oversize) Factory spec.
Maximum wear Allowable limit
Hone to 2.2 to 3.0 μm Rz
Finishing
(0.000087 to 0.00011 in. Rz) ∇∇∇.
2. Replace the piston and piston rings with oversize 0.5 mm (0.02
in.) ones.
NOTE
• When the oversize cylinder is worn beyond the allowable
limit, replace the cylinder block with a new one.

Rotor Lobe Clearance
1. Measure the clearance between lobes of the inner rotor and the
outer rotor with a feeler gauge.
2. If the clearance exceeds the allowable limit, replace the oil pump
rotor assembly.
Factory spec.
Clearance between
inner rotor and outer
rotor
Allowable limit
Clearance between Outer Rotor and Pump Body
1. Measure the clearance between the outer rotor and the pump
body with a feeler gauge.
2. If the clearance exceeds the allowable limit, replace the oil pump
rotor assembly.
Factory spec.
Clearance between
outer rotor and pump
body
Allowable limit
Clearance between Rotor and Cover
1. Put a strip of plastigage onto the rotor face with grease.
2. Install the cover and tighten the screws with the specified torque.
3. Remove the cover carefully, and measure the amount of the
flattening with the scale and get the clearance.
4. If the clearance exceeds the allowable limit, replace oil pump
rotor assembly and the cover.
