4. Refer to Figure 4D-5, check wear of facing by
measuring depth of each rivet head depression,
i.e. distance between rivet head and facing sur-
face. If depression is found to have reached ser-
vice limit of 0.02 inch (0.5 mm) at any of the
holes, replace clutch disc assembly.
5. Refer to Figure 4D-6, check backlash by turning
disc back and forth as mounted on transmission
input shaft. Replace disc assembly if backlash is
noted to exceed 0.04 inch (1.0 mm). Backlash
here is a circular displacement as measured with
a dial indicator.
CLUTCH REASSEMBLY
1. Before reassembling the clutch, lubricate the fol-
lowing components (see Section 11 for recom-
mended lubricants).
•
Clutch release bearing — lubricate inner diam-
eter.
•
Clutch release shaft/fork — lubricate wear sur-
faces.
•
Transmission input shaft — lubricate wear sur-
faces.
•
Clutch release shaft/fork bushings — lubricate
inner diameter.
2. Drive in release shaft/fork bushings to the same
level as outside surface of transmission housing
