４－８－０３
- After the camshaft is removed, clean it carefully with a suitable detergent and dried
with compressed air.
- Measure the camshaft bearing journals and the bearings according to the instructions
given in Section 3.2. If the bushing clearance exceeds the maximum wear value,
new bearings must be installed.
Re-installation of camshaft
- Coat all friction surfaces on the camshaft and the bearing surfaces with clean lube oil.
- Re-install the camshaft in the reverse order of disassembly. If it has been separated
into two section for removal, insert the first section into the block until the coupling
joint is just outside the block, bolt the two sections together to insure proper alignment,
and slide the assembly the rest of the way into the block. Then remove the bolts
that fasten the camshaft sections together, apply Locktite 242 or equivalent,
and torque them the settled value.
- Install the camshaft drive gear. Apply Locktite 242 or equivalent and torque
the bolts to the settled value.

The timing gear train consists of eleven spur gears (Figure 4.8-2) located at
the front of the engine. The gear train should be visually inspected and gear
backlash measured at the settled intervals (Refer to Maintenance Schedule, Section 3.5).
