Clutch Disc: Procedures
INSPECTION
Fluid contamination is a frequent cause of clutch malfunctions. Oil, grease, water, or other fluids on the clutch contact surfaces will cause faulty
operation.
During inspection, note if any components are contaminated. Look for evidence of oil, grease, or water/road splash on clutch components.
OIL CONTAMINATION
Oil contamination indicates a leak at the rear main seal and/or transaxle input shaft. Oil leaks produce a residue of oil on the transaxle housing interior,
clutch cover and flywheel. Heat buildup caused by slippage can bake the oil residue onto the components. This glaze-like residue ranges in color from
amber to black.
GREASE CONTAMINATION
Grease contamination is usually a product of over-lubrication. During clutch service, apply only a small amount of grease to the input shaft splines.
Excess grease may be thrown off during operation, contaminating the disc.
ROAD SPLASH/WATER CONTAMINATION
Road splash contamination is usually caused by driving the vehicle through deep water puddles. Water can be forced into the clutch housing, causing
clutch components to become contaminated. Facing of disc will absorb moisture and bond to the flywheel and/or, pressure plate, if vehicle is allowed to
stand for some time before use. If this condition occurs, replacement of clutch assembly may be required. Drive the vehicle until normal clutch operating
temperature has been obtained. This will dry off disc assembly, pressure plate, and flywheel.
