DISASSEMBLY

1.

REMOVE OIL PUMP COVER
(a) Remove the 3 bolts, then remove the oil pipe.
(b) Remove the 2 O-rings.

(c) Remove the 7 bolts, then remove the oil pump 

cover, drive rotor and driven rotor.

2.

INSPECTION

1.

INSPECT OIL PUMP RELIEF VALVE

2.

INSPECT OIL PUMP ROTOR SET
(a) Place the drive and driven rotors into the timing 

chain cover with the marks facing upward.

(b) Check the rotor tip clearance.

(1) Using a feeler gauge, measure the clearance 

between the drive and driven rotor tips.
Standard clearance:

0.06 to 0.16 mm (0.0024 to 0.0063 in.)

Maximum tip clearance:

0.16 mm (0.0063 in.)

If the clearance is greater than the maximum, 
replace the drive and driven rotors together.

(c) Check the rotor side clearance.

(1) Using a feeler gauge and precision straight 

edge, measure the clearance between the 
rotors and precision straight edge.
Standard clearance:

0.03 to 0.09 mm (0.0012 to 0.0035 in.)

Maximum side clearance:

0.09 mm (0.0035 in.)

If the clearance is greater than the maximum, 
replace the drive and driven rotors. If 
necessary, replace the timing chain cover 
assembly.

(d) Check the rotor body clearance.

(1) Using a feeler gauge, measure the clearance 

between the driven rotor and body.
Standard clearance:

0.250 to 0.325 mm (0.0098 to 0.0128 in.)

Maximum body clearance:

0.325 mm (0.0128 in.)

If the clearance is greater than the maximum, 
replace the drive and driven rotors. If 
necessary, replace the timing chain cover 
assembly.
