The catalogue runs on numbers rather than categories: 671 part numbers across injectors, nozzles, control valves, pumps, sensors, repair kits and service tools, plus 232 numbered tools for common rail, EUI, EUP and HEUI work.

Brand families we quote cover Bosch, Caterpillar, Cummins, Delphi, Denso, Siemens VDO, SsangYong, Zhongdi. Where a part is supplied in a Chinese equivalent, we say so before the order rather than after it.

Zhongdi has spent 14 years on common rail components. Buyers are spread across Asia, the Americas, Europe, Africa and Oceania — Russia, the United States, Brazil, Poland and Australia among them — and a large share of the work comes from customers who keep coming back. The principle behind that is short: integrity first, customer supreme.

How an order runs

Send the OEM number and the engine. We answer with the number we can supply, the brand it comes from and the quantity available. Nothing moves until you confirm that number.

Test benches are quoted separately, with the standard function list and any optional function you need, so the specification is fixed before the machine is built.
