Replacement Hymec clutch slave cylinders

If you have an older Hymec clutch activation system and require a replacement slave cylinder but are not aware of the correct part number, there is a method to make it easier for you to establish the part number for the replacement.
Remove the slave cylinder from the motorcycle and activate the master cylinder until the slave cylinder activation rod is fully retracted and withdrawn. The piston in the slave cylinder is now contacting the bronze cap at the back of the slave cylinder and the rod length should be measured as shown in the schematic. If the slave cylinder is no longer working it can be removed from the pressure line and forced slowly and carefully into the slave cylinder for the measurement. Please note, the length you are measuring is not the activation length, the activation length is 16mm longer than the withdrawn length.
Following the measurement please do not disregard your old slave cylinder you may require the cap or the support. All of our replacement HYMEC slave cylinders are delivered with the standard cap and standard support as shown in the pictures. If the slave cylinder you require lies between two different activation lengths, always order the longer version and use spacers between the support and the cable attachment to increase the activation length to suit your motorcycle.

Dimensions:

• Activation length: 60-62 mm
• Withdrawn length: 45 mm
