INSPECTION
1. INSPECT IDLER GEAR
(a) Using a cylinder gauge, measure the inside diameter of
the idler gear.
Idler gear inside diameter:
44.000 -- 44.025 mm (1.7323 -- 1.7333 in.)
(b) Using a micrometer, measure the diameter of the idler
gear shaft.
Idler gear shaft diameter:
43.955 -- 43.990 mm (1.7305 -- 1.7319 in.)
(c) Subtract the idler gear shaft diameter measurement from
the idler gear inside diameter measurement.
Standard oil clearance:
0.010 -- 0.070 mm (0.0004 -- 0.0028 in.)
Maximum oil clearance: 0.20 mm (0.0079 in.)
If the clearance is greater than maximum, replace the gear and
shaft.
2. INSPECT INJ ECTION PUMP DRIVE GEAR BEARING
Check that bearing is not rough or worn.
If necessary, replace the bearing. (See page EM -- 31)
