In the heavy machinery industry, tracking engine life is non-negotiable. The 161-3932 (also known as 1613932) is the primary service meter used to monitor operational hours for CAT 300C series excavators. Whether you are performing a routine inspection or a complete engine overhaul, ensuring your timer functions correctly is vital for maintenance scheduling.
Our OEM-standard replacement for CAT 161-3932 offers the same reliability as the original equipment but at a much more competitive price point for fleet operators and repair shops.

Protecting your fuel system starts at the tank opening. The 07050-41200 (also searched as 0705041200) is the heavy-duty fuel filler cap designed for Komatsu PC series excavators. A damaged or missing cap leads to fuel contamination, injector wear, and costly engine downtime.
This Komatsu 07050-41200 replacement ensures a vacuum-sealed fit, preventing dust and water from entering the diesel tank during harsh construction site operations.

If your CAT 320C display shows a frozen number or a blank screen despite the engine running, it is time for a replacement. Electrical surges often damage the internal CMOS of the 161-3932. Checking the wiring harness for 24V input is the first step before swapping the unit.
The 07050-41200 fuel cap contains a rubber gasket that degrades over time due to diesel exposure and UV heat. If you notice wet residue around the filler neck, the pressurized seal has failed. Replace immediately to avoid moisture being sucked into the fuel lines during cooling cycles.
