Engine Compatibility
Commonly associated with Volvo Penta TD61AG and TD61G diesel engines. Some Volvo Penta diagram references also associate this pump family with larger industrial/auxiliary engine applications, so final fitment should be checked by serial number and pump tag.
Serial Number Fitment Notice
Confirm fitment by engine model, engine serial number, Volvo Penta parts diagram, and the tag number on the existing pump before ordering. Injection pumps can differ by calibration even when the external pump body looks similar.
When This Part Needs Replacement
Replace or service the injection pump if the engine is hard to start, smokes excessively, lacks power, runs unevenly, surges, leaks fuel, has poor throttle response, or fails fuel-system diagnostic testing.
Installation Notes
Installation should be handled by a qualified diesel technician. Keep the fuel system clean, verify pump timing, replace required seals, prime and bleed the fuel system, and check carefully for leaks after installation.
