INSPECTION
1. INSPECT OIL JET
(a) Check the oil jet for damage or clogging.
If necessary, repair the cylinder block.
2. INSPECT OIL PUMP RELIEF VALVE
(a) Check the relief valve.
(1) Coat the valve with engine oil, and then check
that the valve falls smoothly into the valve hole
by its own weight.
If it does not, replace the relief valve. If
necessary, replace the oil pump assembly.
3. INSPECT OIL PUMP ROTOR
(a) Check the side clearance.
(1) Using a feeler gauge and precision
straightedge, measure the clearance between
the rotors and precision straightedge.
Standard clearance:
0.030 to 0.085 mm (0.0012 to 0.0033 in.)
Maximum clearance:
0.16 mm (0.0063 in.)
If the side clearance is greater than the
maximum, replace the oil pump assembly.
(b) Check the tip clearance.
(1) Using a feeler gauge, measure the clearance
between the drive and driven rotor tips.
Standard clearance:
0.080 to 0.160 mm (0.0031 to 0.0063 in.)
Maximum clearance:
0.35 mm (0.0138 in.)
If the tip clearance is greater than the
maximum, replace the oil pump assembly.
(c) Check the body clearance.
(1) Using a feeler gauge, measure the clearance
between the driven rotor and pump body.
Standard clearance:
0.100 to 0.170 mm (0.0039 to 0.0067 in.)
Maximum clearance:
0.325 mm (0.01128 in.)
If the body clearance is greater than the
maximum, replace the oil pump assembly.

4. INSPECT OIL PUMP DRIVE CHAIN AND 2 OIL PUMP
SPROCKETS
(a) Using vernier calipers, measure the length of the 8
links with the chain fully stretched.
Maximum chain elongation:
52.4 mm (2.063 in.)
If the elongation is greater than the maximum,
replace the chain.
HINT:
Make the measurements at 3 or more places
selected at random.
(b) Wrap the chain around the oil pump sprocket.
(c) Using vernier calipers, measure the sprocket
diameter with the chain.
NOTICE:
Vernier calipers must contact the chain rollers
when measuring.
Minimum sprocket diameter (with chain):
Crankshaft 48.2 mm (1.898 in.)
Oil pump drive shaft 48.2 mm (1.898 in.)
If the diameter is less than the minimum, replace the
chain and sprockets.
5. INSPECT CHAIN TENSIONER PLATE
(a) Measure the chain tensioner plate wear.
Maximum wear:
0.5 mm (0.020 in.)
If the wear is greater than the maximum, replace the
chain tensioner plate.
