IMPORTANT:
Stanadyne DE2 injection pump for 4045H (higher-tier) engines ONLY. Do NOT order for 4045T or 4045D — use RE568070. The H designation means different calibration for emissions and higher power output. Fits excavators (120C/120D/160C), loaders (444J), dozers (450H/450J/550/650), skidders (770D).
Failure symptoms: engine coughing, misfiring, stalling under load, extended crank time, black/white smoke. Supersedes SE501234, RE507968, RE518086, RE518167. Always bleed and prime fuel system after install — dry cranking destroys internals.
⚠️ Verify 4045H on engine nameplate — do not order by machine model alone.
