Driven Plate Assembly
201RS007
1. Visually check the torsion spring for looseness,
breakage, and weakening.
2. If any of these conditions are discovered, the driven
plate assembly must be replaced.
3. Visually check the facing surfaces for cracking and
excessive scorching.
4. Visually inspect the facing surfaces for the presence
of oil or grease.
5. If any of these conditions are discovered, the facing
must be cleaned or replaced.
6. Check that the driven plate moves smoothly on the
transmission top gear shaft spline.
7. Minor ridges on the top gear shaft spline may be
removed with an oil stone.
Driven Plate Warpage
201RS008
1. Insert the clutch pilot aligner into the driven plate
splined hub.
2. The clutch pilot aligner J-24547 must be held
perfectly horizontal.
3. Set a dial indicator to the driven plate outside
circumference.
4. Slowly turn the driven plate.
5. Read the dial indicator as you turn the driven plate.
6. If the measured value exceeds the specified limit, the
driven plate assembly must be replaced.
Driven Plate Warpage
Standard: 0.7 mm (0.028 in)
Limit: 1.0 mm (0.039 in)
Driven Plate Splined Hub Spline Wear
201RS009
1. Clean the driven plate splined hub.
2. Install the driven plate to the transmission top gear
shaft spline.
3. Set a surface gauge to the driven plate outside
circumference.
4. Slowly turn the driven plate counterclockwise.
5. Measure the spline rotation play as you turn the
driven plate.
6. If the measured value exceeds the specified limit, the
driven plate assembly must be replaced.

Rivet Head Depression
201RS010
1. Use a depth gauge or a straight edge with steel rule to
measure the rivet head depression 1 from the facing
surface 2.
2. Be sure to measure the rivet head depression on both
sides of the driven plate.
3. If the measured value is less than the specified limit,
the driven plate assembly must be replaced.
Rivet Head Depression
Standard: 1.95 mm (0.077 in)
Limit: 0.2 mm (0.008 in)
Release Bearing
201RS011
1. Visually check the release bearing for excessive play,
noise and breakage.
2. If any of these conditions are discovered, the release
bearing must be replaced.
3. When replacing the release bearing, replace both the
wedge collar and wire ring at the same time.

fork with an oil stone.
3. Replace any exhibiting excessive wear or damage.
Installation
To install, follow the removal steps in the reverse order,
noting the following points:
1. Install flywheel assembly and crankshaft bearing, use
the installer J-26516-A and driver handle J-8092 to
install the crankshaft bearing then clean and lubricate
with grease.
