INSPECTION AND REPAIR OF OIL PUMP DRIVE
SHAFT, BEARINGS AND BUSHING
1. INSPECT OIL PUMP DRIVE SHAFT
(a) Using a micrometer, measure the journal diameter of
pump drive shaft.
Standard journal diameter:
Front 40.959 - 40.975 mm
(1.6126 - 1.6132 in.)
Rear 32.959 - 32.975 mm
(1.2976 - 1.2982 in.)
(b) Using a cylinder gauge, measure the inside diameter
of the pump drive shaft bearing.
Bearing inside diameter:
Front 41.000 - 41.025 mm
(1.6142 - 1.6152 in.)
Rear 33.000 - 33.025 mm
(1.2992 - 1.3002 in.)
(c) Subtract the journal diameter measurement from the
bearing inside diameter measurement.
Standard oil clearance: 0.025 - 0.066 mm
(0.0010 - 0.0026 in.)
Maximum oil clearance: 0.08 mm (0.0031 in.)
If the clearance is greater than maximum, replace the bear-
ing. If necessary, replace the drive shaft.
2. IF NECESSARY, REPLACE OIL PUMP DRIVE SHAFT
BEARINGS
(a) Using SST, replace the No.1 bearing by using No.2
bearing as a guide.
SST 09215-00100 (09215-00120, 09215-00130,
09215-00140,09215-00160,09215-00210,
09215-00220)
(b) Using SST, replace the No.2 bearing by using the No.1
bearing as a guide.
SST 09215-00100 (09215-00120,09215-00130,
09215-00140,09215-00210,09215-00220)
