How Well Do You Know Clutch Systems?

Study Notes

Clutch pedal position switch prevents starter operation unless clutch is depressed
Symptoms of faulty clutch/linkage/hydraulic system: difficulty shifting gears
Fluid leak repair: tighten loose fittings, replace O-rings, lines, hoses, or cylinders
Insufficient actuator cylinder travel indicates air in the system or faulty cylinder
Clutch slippage diagnosis: stall test or road test
Clutch spin-down test checks for drag or incomplete release
Clutch replacement involves replacing pressure plate assembly, clutch disc, release bearing, and pilot bearing
Flywheel resurfacing recommended for grooves, nicks, or heat damage
Flywheel axial runout checked with straightedge or dial indicator
Inspection during disassembly identifies reusable parts and issues that need attention before reassembly.
Clutch assembly should be inspected visually for damage and wear before replacement.
Flywheel axial and radial runout should be measured and excessive runout indicates worn engine crankshaft thrust bearings.
Pressure plate assembly should be checked for wear, distortion and release lever height after installation.
Clutch disc should be checked for facing thickness, damper spring condition, hub splines wear, contamination, warpage or axial runout.
Housing bore runout should be checked and corrected if possible using eccentric dowel pins.
Release bearing has no effective bench checks and is usually replaced with disc and pressure plate.
Flywheel bolts should be checked and torqued to specifications before clutch assembly replacement.
Pilot bearing should be driven into place and lubricated if necessary.
Clutch disc should be positioned correctly and aligned using an alignment tool or old transmission shaft.
Clutch linkage should be checked for smooth operation and cable should be removed, cleaned and lubricated if necessary.
Lubricate pivot bushings on pivot shafts
Use thin film of grease on clutch splines
Transmission should be completely seated before mounting bolts are tightened
Tighten transmission mounting bolts two turns at a time
Adjust free travel before operating clutch
Clutch hydraulic system can be bled by gravity bleeding or back-bleeding
Clean bleeder valve and place shop cloth under it
Check fluid level and correct if necessary
Some cylinders are difficult to bleed air from and may require bench bleeding or pressure surges
Some clutch hydraulic systems will self-bleed if clutch pedal is held depressed overnight
