About this part
0460424403 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 0460424403, 504208082, 0460424235, 0460424275, 504063803.
The injection pump is what generates injection pressure and meters fuel to each cylinder in firing order. Because it also provides the timing reference, its condition affects starting, smoke, power and fuel consumption together — a pump that is worn rarely produces a single isolated symptom.
The pattern is normally cumulative: slightly harder starting, then noticeable power loss, then smoke and unstable idle. Where the drive seal has failed, diesel in the lubricating oil is the warning that should stop you running the engine.
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.
Fitment notes: this unit must be timed to the engine, not simply bolted on. Never force the shaft to align — turn the engine over to meet it. Prime the system before cranking, fit a new drive seal where specified, and verify supply pressure from the lift pump before start-up. Running a dry pump, even briefly, causes damage that no warranty will cover.
What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.

Fitment note. Several part numbers in this family look similar. Confirm the number on your
existing unit, the engine model and the machine or vehicle application before ordering. Send us a nameplate photo
and we will verify the match before dispatch.
