Injection pumps are calibration-specific: the engine fitment comes from supplier listings, not a Cummins catalogue. Match the number on your existing pump or quote your ESN and CPL. The "6CTA8.9-G2" some listings give is not a DCEC engine designation. Fitment and interchange data is compiled from manufacturer catalogues and cross-reference listings and can change at engine serial-number breaks. Quote your engine serial number and existing part number when you call and we will confirm before dispatch.
About this part
The Cummins 6CTAA8.3 Fuel Injection Pump (BYC, RSV Governor) — part number 5270403 is a genuine Cummins part, supplied at £495 by G Service Power. It is brand new, held in UK stock and dispatched next day, worldwide.
Genuine Cummins fuel injection pump, part number 5270403, made by BYC (Beijing ASIMCO Tianwei) — the pump plate reads BYC 5270403, pump number 10 404 566 071, type CPES6P120D120RS, factory number 15G06269, and the Cummins box label reads PUMP, INJECTION BOSCH, 21 kg, August 2015. An in-line injection pump meters diesel for each cylinder in turn and delivers it at injection pressure to the injectors; the RSV mechanical variable-speed governor (BYC 10 421 535 315) holds whatever speed the control lever selects — the build for industrial and generator-set engines, not electronically governed ones. CPES6P120D120RS is a Bosch P7100-type six-cylinder pump with 12 mm plungers by the Bosch designation. Cummins still lists 5270403 as a current part with no supersession. Parts suppliers list 5270403 and its sibling calibration 5270404 for the Dongfeng Cummins 6CTAA8.3-C260, the 260 hp construction rating Cummins builds with a BYC P7100 pump and RSV governor; one pump list also gives it for the 6CTAA8.3-C240. Injection pumps are calibration-specific, so match the number on your existing pump or quote your ESN and CPL. Supplied with port caps and drive cover fitted, in the original Cummins box; no drive gear, lines or injectors. Condition: brand new, unused, never fitted; box scuffed. One available at £495 plus VAT. Please confirm fitment against your engine serial number before ordering. In UK stock — call +44 7951 632187 or message on WhatsApp for shipping and availability.
