About this part
22100-1C080 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 22100-1C080, 22100-1C050, 221001C080, 221001C050.
An injector is a high-speed valve. It has to hold back rail pressure, then open and close within a fraction of a crankshaft degree — several times per cycle on pilot-injection engines. Anything that alters opening behaviour, whether it is carbon on the tip, a worn needle or a tired solenoid, changes how the cylinder burns its charge.
Common indicators are rough or unstable idle, smoke that was not there before, higher fuel consumption on the same duty cycle, diesel knock under load, and in some cases fuel dilution of the engine oil from an injector that is leaking internally.
A back-leakage comparison across the set is the cheapest meaningful test: uneven return between cylinders points at the failing unit. Follow it with a cut-out test to confirm which cylinder actually stops contributing.
Fitment notes: injectors on the same engine wear together. Replacing only the failed unit often leaves the others close behind, and a single new injector reading differently from its neighbours will cause exactly the rough running you were trying to fix. Replacing as a matched set avoids that. Always fit new copper sealing washers and seals — used washers rarely seal a second time — and where the system requires injector classification or IQA codes, have them programmed to the ECU after fitting.
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.
