Clutch Pack Height

Clutch pack height introduction

The clutch pack height should only be measured if the friction plates and the steel plates have been replaced.

The clutch pack height is critical for a smooth operation of the gear change and needs to be measured prior to installation.

If used steel plates are being fitted, the clutch pack height measurement is not necessary, as the plates may not be worn to the service limit (and are therefore still serviceable), but could fall outside the clutch pack height tolerance when measured.

If building a new clutch pack, its height must be correct. To achieve this, build the new clutch pack with the following:

  • 1 x new inner friction plate

  • 1 x inner steel plate

  • 6 x new friction plates

  • 4 x steel plates, 2.0 mm thick

  • 1 x outer steel plate, 2.3 mm thick.

  • 1 x new outer friction plate

Friction plate and steel plate arrangement

  1. Arrange the new friction and new steel plates in a stack as shown below.
