The fuel injector pump is one of the most critical components in any diesel engine, acting as the heartbeat that feeds pressurized fuel to the injectors. For John Deere’s 4045 engine series from 2006 to 2012, the OEM RE67564 injection pump is engineered to deliver precise fuel pressure, timing, and delivery. When that pump falls out of spec—or fails entirely—engine issues like hard starts, misfires, smoke, and power loss often follow.
-
Precisely times and pressurizes fuel delivery to each cylinder, ensuring efficient atomization and combustion
-
Maintains proper injection pressure across the full RPM range, supporting smooth engine operation
-
Prevents symptoms such as black smoke, rough idle, hesitation, or stalling caused by underperforming pumps
-
Built to factory specifications, with correct tolerances for leakage paths, delivery valves, and rotor/tranfer clearance
-
Helps sustain emissions compliance by ensuring clean, complete combustion rather than poor burn or misfire
-
Durable design resists wear under long service intervals when properly maintained
A failing injector pump is often one of the most expensive surprises under your hood. By replacing or servicing it with the correct OEM RE67564 version, you restore your 4045’s fuel system integrity—and can expect smoother start-up, better throttle response, and improved engine stability. Make sure your fuel system’s “heartbeat” is up to the job.
