Crankshaft and Camshaft Components
Inspection of Camshaft
1. Use V-blocks and a dial indicator to check
camshaft bend (Figure 6-124). Place the
indicator on the center bearing journal.
Figure 6-124
2. Rotate the camshaft and observe the runout.
See Camshaft on page 6-11 for specifications.
3. Measure the height of each lobe
(Figure 6-125, (1)). See Camshaft on
page 6-11 for specifications.
Figure 6-125
4. Measure the diameter of the gear end
(Figure 6-126, (1)), intermediate
(Figure 6-126, (2)), and flywheel end
(Figure 6-126, (3)) bearing journals. See
Camshaft on page 6-11 for specifications.
Figure 6-126
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 6-11 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.
Inspection of Idler Gear and Shaft
1. Measure the outside diameter
(Figure 6-127, (1)) of the idler gear shaft
(Figure 6-127, (2)). See Idler Gear Shaft and
Bushing on page 6-13 for specifications.
2. Measure the inside diameter
(Figure 6-127, (3)) of the idler gear bushing
(Figure 6-127, (4)). See Idler Gear Shaft and
Bushing on page 6-13 for specifications.
