FAQ

Q1: How can I confirm this plunger A157 fits my Hino engine?
A: Please check the part number on your existing injection pump plunger. It should be stamped with “A157” or “131152-3020”. This part is specifically compatible with Hino WO6D, WO6E, and SA6D95L engines, commonly found in Komatsu PC200-6 excavators. If you are unsure, please contact us with your engine serial number for verification.

Q2: What is the installation procedure for this injection pump plunger?
A: Installation requires specialized knowledge of diesel fuel injection systems. We recommend having a qualified diesel mechanic perform the replacement. The process typically involves removing the injection pump, disassembling the pump head, replacing the plunger and barrel assembly, and then recalibrating the pump on a test bench to ensure correct fuel delivery and timing. Improper installation can lead to engine damage.

Q3: How do I maintain the new plunger for a long service life?
A: To ensure longevity, always use clean, high-quality diesel fuel and replace your fuel filters regularly. Contaminated fuel is the primary cause of plunger wear. Additionally, ensure the injection pump is properly lubricated with engine oil. Following the manufacturer’s recommended service intervals for your entire fuel system will maximize the life of this component.
