Accuracy in the gear train is the heartbeat of the Detroit Diesel Series 60. The ATC J-35906-A Cam Gear Pilot is the precision tool that ensures your timing remains rock-solid during every camshaft service.

The Critical Role of Cam Gear Alignment

On a Series 60 engine, the relationship between the camshaft and the gear train dictates fuel injection timing and valve events. Even a slight "cocking" of the gear during installation can result in premature wear, excessive gear noise, or catastrophic timing slips. The J-35906-A functions as a master guide, ensuring the gear slides squarely onto the camshaft hub.

• Dual Bolt Compatibility – Engineered to handle both early (old) and updated (new) cam gear bolt designs in one tool.
• Perfect Centering – Acts as a pilot to maintain concentricity between the camshaft and the gear during the press-fit or bolting phase.
• Anti-Cocked Installation – Prevents the gear from tilting, which protects the high-precision mounting surfaces of the camshaft.
• Smooth Gear Engagement – Ensures the teeth of the cam gear mesh perfectly with the timing train gears upon installation.
• Heavy-Duty Build – A 9.0 lb professional-grade tool designed for the rigors of industrial diesel engine rebuilding.

Precision Timing for Peak Performance

Using the ATC J-35906-A Cam Gear Pilot eliminates the guesswork from engine reassembly. It is an essential safeguard for any technician aiming for long-term component life and factory-spec timing accuracy.
