General Clutch Adjustment

General Clutch Adjustment

Clutch adjustment is usually done in 2 ways:

Most common method – via the adjustment rod:

Rod found under the dash, running from the pedal to the master cylinder

Shortening this rod lowers the clutch take up /engagement point of the clutch

Lengthening the rod raises the clutch take up point.

We advise customers to aim to have the take up point of the clutch at under 40mm off the floor.

This ensures there is sufficient free travel at the top of the pedal.

2A: Internally inside the bell housing on set ups running an internal slave cylinder

In general we like to see 8mm of gap from the clutch fingers to the bearing face, with the bearing fully compressed or pushed right back to the gearbox.

This allows for the clutch diaphragm fingers to “grow” toward the gearbox as the clutch wears.
By completing our custom spec sheet below, we are able to assist you with this:

2B/ Externally we need to ensure the clutch fork and push rod can be compressed into the slave cylinder 20mm from its resting position .

In the case of a cable , lengthening the outer of the cable raises the take up / engagement point of the clutch.

Shortening the outer we see the lowering of the engagement point.

We again advise customers to aim to have the engagement point at less than 40mm off the floor.
