Bell Housing: Testing and Inspection
Clutch Housing Bore Runout
CLUTCH HOUSING
The clutch housing maintains alignment between the crankshaft and transmission input shaft. Misalignment can cause clutch noise, hard shifting,
incomplete release and chatter. Also premature pilot bearing, cover release fingers and clutch disc wear. In severe cases, it can cause premature wear of
the transmission input shaft and front bearing.
NOTE: Only the NV4500 clutch housing can be checked using the following bore and face runout procedures. The NV5600 clutch housing is a
integral part of the transmission and can only be checked off the vehicle.
CLUTCH HOUSING BORE RUNOUT
CAUTION: On diesel engines if housing bore runout exceeds 0.015 inch, the clutch housing/transmission adapter plate must be replaced. On gas
engines if housing bore runout exceeds 0.053 inch the clutch housing must be replaced.
NOTE: Offset dowels are available for gas engines to correct housing bore runout. They are not available for diesel engines.
1. Remove the clutch housing and strut.
2. Remove the clutch cover and disc.
3. Replace one of the flywheel bolts with an appropriate size threaded rod that is 10 inch (25.4 cm) long (Fig. 11). The rod will be used to mount the
dial indicator.
4. Remove release fork from the clutch housing.
5. Install clutch housing. Tighten the housing bolts nearest the alignment dowels first.
6. Mount dial indicator on the threaded rod and position indicator plunger on the clutch housing bore (Fig. 12).
7. Rotate crankshaft until indicator plunger is at the top of the housing bore. Zero the indicator at this point.
