FAQ

Q: How do I confirm this plunger fits my injection pump?
A: Please check the part number stamped on your existing plunger. This part is a direct replacement for M14, M33, M37, and M38 window-type plungers. We also recommend measuring the diameter and length of your current plunger to confirm a match.

Q: What is a “window type” plunger?
A: The “window” refers to the design of the plunger’s control slot or helix, which regulates the amount of fuel injected. This style is common in many in-line injection pumps for excavators and industrial engines. Using the correct window type is critical for proper engine timing and power output.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel technician. The plunger must be cleaned and lubricated with clean diesel fuel or assembly oil before installation. Ensure the plunger rotates freely in the barrel and is timed correctly with the pump’s control rack. Improper installation can lead to engine damage or poor performance.
