Guangzhou Pinxin Engine Expands CAT Genuine Parts Range for Excavator Diesel Engine Rebuilds
Filters, injectors, water pumps, thermostats, piston kits and cooling components consolidated into one supply line for workshops, distributors and rental fleets.
Guangzhou Pinxin Engine Co., Ltd. has broadened its CAT Genuine Parts programme, consolidating the components most often requested during excavator diesel engine rebuilds into a single supply line. Instead of quoting each item separately, the company now builds rebuild packages around the engine family and the machine it sits in, so a workshop can order a complete overhaul set in one enquiry and receive consistently matched parts.
The range covers filtration, fuel delivery, cooling and internal engine parts for the C4.4, C7, C7.1, C9, C9.3, C13, C15, C18, 3304, 3306, 3406, 3508, 3512 and 3516 families. Typical enquiries include the 4P-5500 filter set for 3508, 3512 and 3516 engines, the 1R-0726 oil filter and the 243-6350 air filter in routine service kits, the 236-0962 and 557-7627 fuel injectors for C-9, C7 and C9 rebuilds, the 326-4635 pump head for 320D and 323D machines, the 376-4216 water pump for C13 units, the 377-3016 thermostat for C9.3 engines, and the 574-9895 piston ring kit together with the 391-3732 piston kit for C7.1 overhauls.
Part Numbers in Both Formats
Service documentation from mining, construction and power generation fleets is not consistent, and purchasing systems often store a reference differently from the way it appears on a workshop job card. The same component therefore travels under two spellings, with and without the separator. Pinxin Engine quotes 4P5500 and 4P-5500 for the same filter, 1R0726 and 1R-0726 for the oil filter, 2360962 and 236-0962 for the C-9 injector, 3764216 and 376-4216 for the C13 water pump, and 5749895 and 574-9895 for the C7.1 piston ring kit. The 9Y3333 heat exchanger core for 3304 and 3306 engines, the 5207951 screw bolt for 3512 assemblies and the 2968388 impeller for C12, C15, C18 and 3406E engines are handled in the same way, so an enquiry written in either style reaches the correct part without back-and-forth clarification.

Why Distributors and Repair Groups Work With Pinxin
Rebuild-Level Assembly
Parts are grouped by engine family and machine model, so a single enquiry covers a full overhaul instead of scattered line items.
Both Number Formats
Quotations and packing lists carry part references in hyphenated and unhyphenated style, matching whatever the buyer system stores.
Mixed Model Orders
Fleets running several engine families can consolidate filters, injectors and cooling parts into one order for warehouse restocking.
Workshop-Ready Packing
Components are wrapped and labelled for direct shelf placement, with neutral or buyer-branded packaging available on request.
Supporting Rebuild Programmes Across Mining, Construction and Power Generation
Most demand for this range comes from operators running high-hour equipment where downtime is measured in lost production rather than lost hours. A 320D or 323D excavator working a quarry shift needs the 326-4635 pump head back in service quickly, a 3508 or 3512 generator set needs the 4P-5500 filter set on a predictable interval, and a C13 unit in a rental fleet needs the 376-4216 water pump alongside the matching thermostat. Pinxin Engine builds its stock profile around that reality, holding the fast-moving items in depth and quoting the slower internal engine parts against confirmed engine and arrangement numbers.
- Service and filtration items held in depth for 3508, 3512 and 3516 generator sets.
- Injectors and pump heads quoted against the engine model and arrangement number.
- Cooling parts matched to the machine model for 320D, 323D, 336 and 336E excavators.
Export Markets Served
Enquiries for CAT Genuine Parts currently arrive mainly from Australia, Canada, Chile, Zambia, the Congo, Nigeria, Ghana, Tanzania, Indonesia, Thailand, Malaysia, Zimbabwe, Brazil, South Africa, Saudi Arabia, Mozambique, Peru, Argentina, Vietnam and Kenya. Buyers in these markets typically operate mixed fleets across mining, construction, agriculture and standby power, and they value a supplier who can confirm fitment from a machine model and a part reference rather than from a photograph. Orders are consolidated for container and air shipment so that a single load can cover several engine families at once.
Start an Enquiry
Send the engine model, the machine model and the part reference in whichever format your system uses. The team at Guangzhou Pinxin Engine Co., Ltd. will confirm the matching component and assemble a rebuild package around your fleet.
