In automobiles, the clutch is a part of the transmission that allows for engine engagement and disengagement in order to prevent gear grinding while shifting. A clutch fork is a key part of the machinery.
Identification
Clutch forks are made of steel and shaped like a two-pronged fork, with the exact size and dimensions varying according to vehicle.
Fact
The clutch fork connects the clutch release bearing, sometimes called a throw-out bearing, to the slave cylinder, which has its other end attached to the clutch fluid line. The slave cylinder is what moves the clutch fork.
Function
Once activated, the clutch fork pivots on a rocker and slides the release bearing along the transmission input shaft and into the clutch unit. This applies enough pressure to disengage the clutch and stop engine power transfer to the drive wheels.
Considerations
A rubber boot is sometimes fit over the clutch fork to prevent dirt, oil, rocks, water, and other debris from infiltrating the clutch unit.
Types
There are two main types of clutch forks: forged steel and stamped steel. Forged steel forks connect to the pivot rocker with a spring-wire that fits into a grooved slot on the rear of the fork. Stamped steel forks connect with a riveted flat steel retainer spring.
