CLUTCH PEDAL STOP
A positive clutch pedal stop must be used to prevent over-stroking the hydraulic release bearing
piston and the clutch. For access reasons, in many cars it is not easy to determine how far the
master cylinder is being stroked.
The method listed below provides a very effective method for adjusting the pedal stop:
1. Lift the drive wheels off the ground and support the car on jack stands.
2. With the engine off, place the gearbox in first gear and have someone attempt to rotate the
drive wheels.
3. Depress the clutch pedal slowly until the clutch disengages and the drive wheels can be
rotated.
4. Adjust pedal stop to allow another 1/4" of pedal travel. This should provide clean release of
the clutch. Do not stroke the pedal any further than this point throughout this procedure,
otherwise you will over-stroke the clutch.
MAINTENANCE
A few basic procedures will help to ensure that your hydraulic release assembly will provide a long
and dependable life.
1. Spin the bearing race and check how it feels. If it has a higher than normal resistance or feels
rough, replace the bearing.
2. The piston can be removed and replaced without breaking the hydraulic seal or requiring
bleeding. Periodically, remove the piston and check for any scores in the bore or on the piston
surface. Wipe the piston and orange dust wiper seal before reinstalling. You may find that the
piston is not dry. This could be the rubber grease used when installing the new seal. Do not
mistake this for brake fluid.
3. If the seal needs replacing, order Tilton’s replacement seal kit (P/N 62-905). Instructions and
the correct installation grease are included in the kit. We also recommend the use of a seal
installation tool (P/N 96-002) to prevent damaging the seal during installation.
SERVICE INFORMATION
1. Contact Tilton’s Repair Department (805-688-2353) and describe the problem or the service
that is required.
2. If the bearing assembly needs to be sent in, a Returned Merchandise Authorization (RMA)
number is required and will be provided by a Tilton representative.
