FAQ

Q1: Is this kit a direct fit for my DP pump, or will machining be required?
A1: This is a precision direct-fit replacement kit designed to the original OEM specifications (7189100DS). No additional machining should be required for proper installation in a standard, unworn pump housing. Always clean and inspect the pump bore before installation.

Q2: What is included in the “Cam Ring & S-Plate Kit”?
A2: The kit includes the cam ring and the corresponding S-plate (side plate), which are key interacting components within the injection pump that control the movement of the plungers. Replacing them as a matched set is crucial for balanced performance and longevity.

Q3: What are the signs that my DP pump needs this cam ring and S-plate kit?
A3: Common symptoms include erratic engine performance, loss of power, difficult starting, uneven cylinder firing, or excessive fuel delivery variation between cylinders. A worn cam ring and S-plate can directly affect injection timing and pressure. Professional diagnosis is recommended to confirm.
