About this part
0445020527 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 0445020527, 0445020528, 04132378, 04132090. Application recorded for this part: Fits Deutz.
Supply pressure, timing and delivery quantity are all set here. Failures tend to progress gradually — a little more smoke, slightly harder starting when hot, slowly rising consumption — which is why they are often attributed to the injectors before the pump is checked.
Expect extended cranking especially when hot, hesitant throttle response, smoke that persists rather than clears, timing that drifts or will not hold, and in some cases fuel in the sump or a pump body running unusually hot.
Eliminate the cheap causes first: filter condition, lift pump output, suction-side air leaks, fuel quality. Only then have delivery quantity and timing tested before committing to a replacement unit.
Fitting notes: timing is everything here. Set the pump against the engine's timing marks rather than forcing anything, prime thoroughly before cranking, and check that the lift pump is delivering adequate supply pressure. Also replace the mounting seal and confirm there is no air left in the system before the first start.
Rebuilt rather than refurbished: full teardown and measurement, worn components replaced instead of cleaned and reused, sealing surfaces restored to specification, then bench calibration and testing. The record is what separates this from a used part — we can provide the test sheet for your order. Covered by a 12-month warranty.
