Front Gear Housing Cover and Gear Train
Troubleshooting the front gear housing cover and gear train
consists of:
» Checking for leaks at the front cover, timing pin assembly,
injection pump and the front crankshaft oil seal.
- Inspecting the gears and measuring backlash when
required.
A vibration damper is located on the front of the engine
crankshaft. When diagnosing a vibration problem, check the
damper for visible wobble when routing.
Verify that the index lines (A) are aligned. If the lines are more
than 1.59mm [1 /16 Inch] out of alignment, replace the damper.
Inspect the rubber member (B) for deterioration and missing
pieces.
As previously discussed in the fuel system, replacement of the
gear housing or the timing pin assembly necessitates a
realignment of the pin assembly. The pin must be aligned to
correspond to TDC for Cylinder Number 1.
Flywheel Housing and Flywheel
Diagnostics of the flywheel housing and flywheel is normally
limited to a visual inspection of the parts for damage or wear.
The flywheel and housing are precision made and aligned per
SAE J1033 standard.
