28484198 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 28484198, 1042300FD020. Application recorded for this part: Fits JAC — JAC. 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. 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. Check supply pressure at the pump inlet and look for air in the clear line before assuming internal wear. Plenty of pumps get replaced for a blocked filter or a suction leak that costs a fraction to put right. Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
