FAQ
Q1: How do I identify the correct delivery valve for my injection pump?
A: Check the model number stamped on your injection pump’s nameplate (e.g., P77, P81, P84, P85, P88). Then match it with the corresponding OEM number (134110-7820 for P77, 134110-8220 for P81, etc.). If unsure, measure the valve diameter and height to compare with the specifications provided.
Q2: What are the symptoms of a faulty delivery valve?
A: Common signs include hard starting, unstable idling, black smoke from the exhaust, reduced engine power, and fuel leakage from the injection pump. Replacing worn delivery valves restores proper fuel pressure and timing.
Q3: Can I install these valves myself, or do I need a professional?
A: Installation requires mechanical knowledge of fuel injection systems. While it is a straightforward replacement for experienced technicians, we recommend having a qualified diesel mechanic perform the work to ensure correct torque settings and to avoid contamination of the fuel system.
