FAQ

Q1: Is this the same as the fuel injection pump for the 6CT8.3 engine?
A1: Yes, part number 4935006 is specifically designed as the oil delivery pump for the 6CT8.3 and 6CTA8.3 engines. While it is part of the fuel system, it is technically an oil pump that delivers pressurized oil to the injectors. Ensure your engine requires this specific model by checking your old part number.

Q2: What is the typical installation process for this pump?
A2: Installation involves removing the old pump, cleaning the mounting surface, and bolting the new pump into place. It is recommended to replace the O-rings and gaskets (not included) during installation. Torque the mounting bolts to manufacturer specifications (typically 30-40 ft-lbs). Always prime the pump with clean oil before starting the engine to avoid dry start.

Q3: How do I know if my 4935006 pump is failing?
A3: Common signs of failure include low oil pressure warnings on the dashboard, unusual noise from the pump area, visible oil leaks around the pump housing, or engine hesitation/stalling. If you experience these symptoms, replace the pump immediately to prevent damage to the engine’s internal components.
