Taking the Mystery Out of Clutch Adjustment with Concentric Slave Cylinders
Proper clutch adjustment is a must for correct operation and durability of the clutch components. For many years, clutch engagement and release was performed with a manual linkage or an external hydraulic system. The manual linkages were adjusted by threaded rods that were set to provide proper engagement and proper clutch release, which was relatively simple to achieve. External hydraulic systems used an externally mounted slave cylinder that actuated the clutch fork and were adjustable through a threaded rod from the slave cylinder to the clutch fork. Hydraulic systems have their own challenges, which mainly revolve around proper bleeding technique to ensure that there is no air trapped in the system.
