STEP 2 Cam Finger is knocked toward the inside diameter region of the Body for Cam Fingers. The Cam Finger pushes against the Locking Pin.

STEP 3 A portion of Locking Pin breaks cleanly away and travels with the moving Cam Finger toward the inside diameter of the Body for Cam Fingers.

NOTES: •

BL Assembly

Cold rolled, low carbon steel must be used as a removal punch to avoid damaging the Cam Fingers and/or Body. The contact surface of the punch (where it rests against the Cam Finger) should be profiled with a curved surface that matches the exposed surface of the Cam Finger.

STEP 4 Both the Cam Finger and broken piece of Locking Pin drop into the inside diameter of the Body for Cam Fingers.

Ensure that Body for Cam Fingers is

firmly retained before attempting Cam Finger removal.
