DB4427-4939 RE46959 Injection Pump identification and compatibility

The DB4427-4939 RE46959 Injection Pump should be selected by part number and verified against the component removed
from the engine. Vehicle model names alone are not sufficient because the same model can use
different fuel-system versions in different markets or production periods. Compare the number
on the old component, connector layout, mounting points, fuel connections and the visible body
shape. Please confirm OE number, engine model or old part photos before ordering.

Practical checks before replacing this fuel injection pump

Hard starting, unstable idle, smoke, loss of power or unusual fuel consumption can have more
than one cause. A workshop should check fuel quality, supply pressure, return flow, wiring,
compression and related control components before deciding that replacement is required.
Diagnostic results should be considered together with the engine code and the number on the old
part. This avoids ordering by appearance only and helps distinguish a component fault from a
fuel-supply or electrical problem.

Installation and commissioning

Installation should be completed by a qualified diesel technician using clean tools and the
correct workshop procedure. Protect open fuel connections from contamination, replace required
seals, and follow the vehicle or engine manufacturer’s tightening and cleanliness instructions.
Some applications may require calibration data, coding, adaptation or relearn procedures, while
others do not. The applicable service information and diagnostic equipment should determine the
correct process for the specific engine.
