This is a Cummins ISX Signature Timing Tool Kit. This kit
includes the crank pin, the 4 degree, the 7 degree, and QTY (2) 6
degree wedges.
This is a replacement of the Cummins 3163021. MADE IN USAThe ATC-20161 Cummins ISX Cam Timing Tool Set is a precision-engineered service kit designed to accurately set and verify camshaft timing on Cummins ISX / ISX15 / QSX15 engines. Built as a direct functional replacement for OEM tool 3163021, this kit ensures correct synchronization between the camshaft, crankshaft, and timing components during major repairs, in-frame overhauls, camshaft replacement, or top-end service.
Proper cam timing is critical on ISX engines due to their electronically controlled fuel system, overhead cam design, and tight emission-compliance tolerances. Even slight timing deviations can lead to hard starts, power loss, injector misfire, turbocharger performance issues, excessive smoke, and long-term engine damage. The ATC-20161 tool set eliminates these risks by providing the exact alignment and locking interfaces required to set timing to Cummins specifications.
Manufactured from high-strength, shop-grade materials, this tool set is ideal for dealership-level technicians, rebuilder facilities, and fleet maintenance operations performing precise overhead and camshaft procedures on ISX platforms.
