Inspection of Camshaft
1. Use V-blocks and a dial indicator to check camshaft bend
(Figure 204). Place the indicator on the center bearing
journal.
2. Rotate the camshaft and observe the runout. See
"Camshaft" on page -97 for specifications.
3. Measure the height of each lobe (1, Figure 205) See
"Camshaft" on page -97 for specifications.
4. Measure the diameter of the gear end (1, Figure 206),
intermediate (2, Figure 206) and flywheel end (3, Figure
206) bearing journals. See "Camshaft" on page -97 for
specifications.
Inspection of Camshaft Bushing and Bores
1. Measure the I.D. of the front bushing and the remaining
bores in the cylinder block. See "Camshaft" on page -97
for specifications.
2. If the camshaft bushing is not within specification, replace
it using the appropriate service tool. If the remaining bores
are not within specification, the cylinder block will require
replacement as there are no bearing inserts used.
