The ATC J35596 Cam Gear Lash Adjusting Tool is a precision service tool designed specifically for setting and adjusting camshaft gear lash on Detroit Diesel 60 Series engines. This tool is used during camshaft, gear train, and timing service to accurately position the cam gear and achieve the correct backlash between mating gears, as specified by Detroit Diesel service procedures.
Proper cam gear lash is critical to valve train durability, timing accuracy, and noise control on Detroit Diesel 60 Series engines. Excessive lash can cause gear noise, accelerated wear, and timing instability, while insufficient lash can lead to gear binding and premature failure. The ATC J35596 provides technicians with a controlled, repeatable method to set lash precisely, eliminating guesswork and reducing the risk associated with improvised adjustment methods.
Designed for professional diesel technicians, rebuild shops, and fleet maintenance facilities, this tool is essential when performing camshaft replacement, gear train service, engine overhauls, or timing verification on 60 Series engines.
