IDLER GEARS AND CAMSHAFT DRIVE GEAR REPLACEMENT - CONTINUED
INSPECTION - CONTINUED
Measure OD of idler gear ring dowel. Measurement must be 0.7566 to 0.7576 in. (19.217 to 19.243 mm).
OUTSIDE DIAMETER, IDLER GEAR RING DOWEL
Measure thickness of all thrust bearings in three places 120 degrees apart. Measurement must be 0.0945 to 0.0972 in.
(2.400 to 2.470 mm).
THICKNESS, THRUST WASHER
Inspect camshaft drive gear and thrust plate as follows:
Visually inspect camshaft drive gear for cracks, chips, or broken teeth. Inspect bore of gear and keyway for burrs
or frets. If burrs or frets cannot be removed, or other damage is present, replace camshaft drive gear.
Measure inside diameter of gear bore. Measurement must be 1.8469 to 1.8479 in. (46.912 to 46.938 mm). If mea-
surement is not within specification, replace camshaft drive gear.
Measure camshaft thrust plate inside diameter. Measurement must be 2.1890 to 2.2287 in. (55.60 to 56.61 mm). If
measurement is not as specified, replace thrust plate.
Measure camshaft thrust plate thickness. Measurement must be 0.3528 to 0.3559 in. (8.960 to 9.040 mm). If mea-
surement is not as specified, replace thrust plate.
