INSPECTION
• If any clearance of the oil pump exceeds the
specified service limits, replace the oil pump
as
an
assembly.
OIL PUMP BODY (RIGHT CRANKCASE)
Check the oil pump body sliding surface for wear or
damage.
Measure the I.D. and depth of
oil
pump body.
STANDARD:
OIL PUMP BODY I.D.:
23.150-
23.180
mm
(0.9114 - 0.9126 in)
OIL PUMP BODY DEPTH: 7.020 - 7.090
mm
(0.2764 - 0.2791 in)
• Measure at several points and use the largest
reading.
OUTER ROTOR
Check the oil pump outer rotor sliding surface for wear
or damage.
Measure the
0.0.
and
height of outer rotor.
STANDARD:
OUTER ROTOR O.D.: 22.970 - 23.000 mm
(0.9043 - 0.9055 in)
OUTER ROTOR HEIGHT: 6.960 - 6.980
mm
(0.2740 - 0.2748 in)
• Measure
at
several points and use the smallest
reading.
Calculate the
oil
pump body-to-outer rotor clearance.
SERVICE LIMIT: 0.35
mm
(0.014 in)
Calculate the side clearance.
SERVICE LIMIT: 0.15
mm
(0.006 in)
