5.2 INSPECTION FOR OVERHAUL
5.2.1 SPLINE BACKLASH BETWEEN
CLUTCH DISC BOSS AND MAIN
SHAFT
1. Mount the clutch disc to the main shaft.
2. Hold the main shaft so that it does not turn.
3. Rotate disc lightly and measure the displacement
around the disc edge.
4. If the measurement exceeds the allowable limit, re-
place it.
5.2.2 CLUTCH DISC WEAR
1. Measure the depth from clutch disc surface to the
top of rivet at least 10 points with a depth gauge.
2. If the depth is less than the allowable limit, replace
it.
3. If oil is sticking to clutch disc, or disc surface is
carbonized, replace it.
In this case, inspect transmission main shaft oil
seal, engine rear oil seal and other points for oil
leakage.
5.2.3 PRESSURE PLATE FLATNESS
1. Place a straightedge (1) on the pressure plate and
measure clearance with a feeler gauge (2) at sev-
eral points.
2. If the clearance exceeds the allowable limit, replace
it.
3. When the pressure plate is worn around its outside
and its inside surface only is in contact with the
straightedge, replace even if the clearance is within
the allowable limit.
