3.
Using dial indicator with magnetic base (Figure 7, Item 33), measure runout of intermediate camshaft
journals (Figure 7, Item 34) with end journals mounted on V-blocks. Replace camshaft if runout exceeds
0.002 inch (0.050 mm).
4.
Examine faces of thrust washers for scoring and wear. New thrust washers are 0.208 to 0.210 inch
(5.283-5.334 mm) thick.
5.
Examine surfaces which thrust washers contact. Smooth scratched or scored surfaces with oil stone.
NOTE
Camshaft bearings are available in 0.010 and 0.020 inch (0.254 and 0.508 mm)
undersize on inside diameter.
If camshaft bearings require replacement, see Cylinder Block Maintenance
(WP 0098).
6.
Using micrometer depth gage set and telescoping gage set, measure outside diameter of camshaft journals
and inside diameter of camshaft bearings. Clearance between journals and bearings should be
0.0035–0.007 inch (0.089-0.177 mm) with new parts and a maximum of 0.008 inch (0.203 mm)
with used parts.
7.
Examine teeth on gears for scoring, pitting, and wear.
8.
Inspect idler gear bearing for scoring, pitting, and wear.
9.
Examine gear hub and thrust washers for scoring and wear.
10.
Inspect tachometer drive shaft for distortion or other damage. If damage, discard.
