Hydraulic Clutch

The hydraulically operated clutch is adjusted by changing the length of the slave cylinder pushrod. To adjust a hydraulic clutch, simply turn the nut or nuts on the pushrod as needed.

Note

When a clutch adjustment is made, refer to the manufacturer's service manual for the correct method of adjustment and clearance. If no manuals are available, an adjustment that allows 1 1/2 inches of clutch pedal free travel will allow adequate clutch operation until the vehicle reaches the shop and manuals are available.

Clutch Troubleshooting

An automotive clutch normally provides dependable service for thousands of miles. However, stop and go traffic will wear out a clutch quicker than highway driving. Every time a clutch is engaged, the clutch disc and other components are subjected to considerable heat, friction, and wear.

Operator abuse commonly causes premature clutch troubles. For instance, "riding the clutch," resting your foot on the clutch pedal while driving, and other driving errors can cause early clutch failure.

When a vehicle enters the shop for clutch troubles, you should test drive the vehicle. While the vehicle is being test driven, you should check the action of the clutch pedal, listen for unusual noises, and feel for clutch pedal vibrations.

There are five types of clutch problems—slipping, grabbing, dragging, abnormal noises, and vibration. It is important to know the symptoms produced by these problems and the parts that might be causing them.
