FAQ

Q1: Is this fuel injection pump a direct bolt-on replacement for my Komatsu ZX65 with a Yanmar 4TNV84T engine?

Yes, this pump (OE 729659-51360) is designed as a direct, bolt-on replacement for the original pump on the Yanmar 4TNV84, 4TNV84T, 4TNV88, and 3TNV88 engines, commonly found in the Komatsu ZX65 excavator. No modifications are required for installation.

Q2: Does the pump come pre-calibrated, or do I need to set the timing?

The pump is pre-calibrated from the factory for standard engine specifications. However, due to variations in engine wear and application, we strongly recommend that a qualified diesel technician verify and adjust the injection timing according to the engine’s service manual during installation to ensure optimal performance.

Q3: What is the recommended maintenance for this fuel injection pump?

To ensure maximum service life, always use clean, high-quality diesel fuel and replace your fuel filters at the manufacturer’s recommended intervals. Regularly check for any fuel leaks around the pump and high-pressure lines. Contaminated fuel is the primary cause of premature pump failure.
