RETAINER-OVERRUNNING CLUTCH CAM/OVERDRIVE PISTON
DESCRIPTION
The overrunning clutch consists of an inner race (5),
an outer race (or cam) (1), rollers (2) and springs (3),
and the spring retainer (4). The number of rollers and
springs depends on what transmission and which
overrunning clutch is being dealt with.
OPERATION
Astheinnerraceisrotatedinaclockwisedirection(asviewedfromthefront of the transmission), the race causes
the rollers to roll toward the springs, causing them to compress against their retainer. The compression of the
springs increases the clearance between the rollers and cam. This increased clearance between the rollers and cam
results in a freewheeling condition. When the inner race attempts to rotate counterclockwise, the action causes the
rollers to roll in the same direction as the race, aided by the pushing of thesprings. As the rollers try to move in the
same direction as the inner race, they are wedged between the inner and outer races due to the design of the cam.
In this condition, the clutch is locked and acts as one unit.
DISASSEMBLY
