CAUTION: Clutch disc may contain asbestos fibers which can cause
serious health risk. DO NOT sand clutch components. DO NOT
clean components using compressed air. To clean components,
use a water-dampened cloth.
Removal
With transmission and clutch housing removed, mark pressure
plate and flywheel for reassembly reference. Install clutch aligner in
clutch disc to prevent disc from falling. Loosen pressure plate bolts
evenly and in rotation to avoid warping pressure plate. Remove
pressure plate and disc from flywheel. See Fig. 10.
Inspection
1) Check for oil leakage through engine rear main bearing oil
seal and transaxle input shaft seal. Check flywheel and pressure plate
for burned areas, discoloration, cracks, grooves or ridges. Replace as
necessary.
2) Use medium sandpaper (80-180 grade) to clean flywheel
surface, then wipe with mineral spirits. DO NOT flat-machine flywheel
surface. Check facing surfaces for grease or oil contamination. Check
clutch disc for wear. Clutch disc face-to-rivet head distance should
be at least .008" (.20 mm). Check splines of disc hub and transaxle
input shaft.
3) Using straightedge, check pressure plate. Friction area
should be flat to slightly concave, with the inner diameter about 0-.
0039" (0-0.1 mm) less than outer diameter. Using surface plate, check
clutch cover for flatness. Sections around bolt holes should contact
surface plate within .015" (.38 mm). Ensure cover-to-flywheel dowel
fit is snug. Replace clutch assembly as necessary.
NOTE: Before installing clutch disc, ensure flywheel mating
surface, pilot bearing/bushing and clutch release bearing are
in satisfactory condition. Repair and/or replace components
as necessary.
Installation
To install, reverse removal procedure using clutch aligner.
Ensure reference marks are aligned. Tighten pressure plate retaining
bolts evenly a few threads at a time to prevent warpage. See TORQUE
SPECIFICATIONS table.
