HONDA V45 TECHNICAL FEATURES AUTOMATIC CAM CHAIN TENSIONER GENERAL The tensioner consists of an arm, slipper, spring, lock plate, lock rod and cam chain guide. The self-locking rod is connected on one end to the slipper and on the other end to the lock plate as shown. The spring maintains constant pressure to hold the slipper against the cam chain at all times. The lock plate prevents backward movement of the lock rod and tensioner slipper. CAM CHAIN GUIDE TENSIONER SPRING TENSIONER ARM TENSIONER SLIPPER OPERATION As the cam chain wears, the spring pulls the slipper to compensate by forcing the lock rod out. The lock plate prevents the rod from being pushed in by the cam chain during operation. Rod is pulled by spring at all times. Rod is prevented from moving in the direction of the arrow by this lock plate. Date of Issue: May, 1982 351 0 HONDA MOTOR CO., LTD.
