Upgrade the reliability and precision of your Case backhoe engine with the J931623 DCEC Original Cummins Valve Tappet.
This genuine Cummins component ensures accurate transfer of camshaft motion to the engine valves, maintaining proper timing, smooth operation, and efficient combustion.

As an original DCEC Cummins part, the tappet is manufactured with high-strength alloy steel, precision-ground surfaces, and OEM-standard hardness—ideal for heavy-duty diesel engines used in Case 580 models.

Worn tappets can cause engine ticking sound, valve clearance issues, power loss, and uneven combustion. Replacing them during top overhaul or full engine rebuild restores engine performance and reduces noise.
