A: Please cross-reference your existing part number with our OEM numbers: 108-6633, 1086633, 108-6634, or 1086634. This plunger is a standard-size component. If your pump uses a different number, please contact us with your original part details for verification before ordering.

Q2: What is the recommended installation procedure for this plunger element?

A: Installation should be performed by a qualified diesel technician. The plunger must be perfectly clean and lubricated with clean diesel fuel or assembly oil before insertion into the pump barrel. Ensure the plunger’s alignment slot matches the guide pin in the barrel. Incorrect installation can cause immediate pump failure.
