04287049 is supplied as a remanufactured replacement unit pump. Cross-reference numbers: 04287049, 0428-7049. Application recorded for this part: Fits Deutz. This pump has two jobs that are easy to conflate: raising fuel to injection pressure, and metering the correct quantity at the correct moment. Wear affects both. The result is usually a combination of harder starting, drifting timing and visible smoke rather than one clean fault. Look for extended cranking, especially hot, poor throttle response, smoke across the rev range, fluctuating idle speed, and a gradual rise in consumption that cannot be explained by duty cycle. Confirm you actually need a pump. Verify supply pressure at the inlet, check for air ingress and restrictions, and have delivery and timing tested on the bench — many 'worn pumps' turn out to be supply faults. 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. How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
