Product Description Cam Clamp Universal Timing Gear Locking Tool The KD 3840 is specifically designed to retain sprocket wheels to maintain proper timing during Timing belt service. This is critical, since the timing of Dual Overhead Systems is time consuming and expensive if the cams get out of position during belt service. Works on both Dual and Quad systems. Patented Uni-Tooth design works on both USA and Imports by gripping the geared side of the Cam Sprocket. Competitive designs grip the inside walls, do not have a positive grip, and are prone to slippage particularly above spacing of 1".
