On a Detroit Diesel Series 60, "close enough" gear lash leads to premature failure and excessive noise. The ATC J35596 is the precision-engineered solution for perfect backlash every time.

The High Stakes of Gear Backlash

The gear train of the Series 60 is a masterclass in heavy-duty engineering, but it relies on exact tolerances. If your cam gear lash is too loose, you get gear "clatter" and timing instability. Too tight? You risk gear binding, heat buildup, and catastrophic tooth failure. The ATC J35596 provides the mechanical control needed to position the gear exactly according to Detroit Diesel factory specifications.

• Precision Positioning – Enables micro-adjustments to the cam gear for the perfect mating relationship.
• OEM-Equivalent Accuracy – Matches the function of J-35596 to meet all factory service manual requirements.
• Timing Stability – Ensures the mechanical synchronization between the crank and cam remains true over the engine's life.
• Noise Reduction – Eliminates the annoying and destructive gear whine associated with improper lash settings.
• Heavy-Duty Reliability – Constructed from professional-grade materials to handle the rigors of high-volume rebuild shops.

Precision That Protects Your Rebuild

Using the ATC J35596 Lash Adjusting Tool is the mark of a professional diesel technician. Don't risk gear train damage on an expensive overhaul—set it right the first time.
