FAQ

Q1: How do I confirm if this PM5 U155 plunger fits my injection pump?

A: Please cross-check the existing part number on your plunger or pump housing. This part is confirmed for PM5 and U155 series pumps. If your part number is XY95PM45, PM5, or U155, it is a direct match. If unsure, please contact us with a photo of your old part.

Q2: What is the recommended installation procedure?

A: Installation should be performed by a qualified diesel technician. Ensure the pump housing and bore are perfectly clean. Lubricate the plunger with clean diesel fuel during assembly. Do not force the plunger; it should slide smoothly. Torque all retaining components to manufacturer specifications.

Q3: How should I store spare plunger assemblies?

A: Store in a cool, dry environment. Keep the plunger and barrel assembly sealed in its original anti-corrosion packaging until ready for use. Avoid exposure to moisture or dust, as contamination can damage the precision surfaces.
