Beijing XLHJ International Trading Company Ltd supplies genuine parts for Caterpillar off-highway and mining trucks

Beijing XLHJ International Trading Company Ltd supplies genuine parts for Caterpillar off-highway and mining trucks of the 777, 785, 789, 793, 794, 796, 797 and 798 families. We select and supply parts by machine serial number and the Cat parts catalog. This approach eliminates part-number errors and downtime caused by an incompatible component.

Models we support

Nominal payload and power depend on the generation and configuration of each machine, so the model name alone is not enough to identify the right part.

Why we select parts by serial number

Within a single model, Cat has built machines with different engines, power ratings, transmissions, tires and bodies. For example, the 785G was offered with two engine power ratings, the 789D with the 3516C and 3516B engines, the 793D comes in five arrangements for different operating conditions, and the 793F is built on a different engine family (C175, while the 793B–D use 3516 engines). A part that fits one version may not fit another.

The serial number identifies the exact machine configuration. Our engineer uses it to find the part in the Cat catalog and confirm the part number before you order.

Main assemblies we supply

We focus on the assemblies and components that determine whether the truck keeps running:

• Engine and fuel system: turbochargers, fuel pumps, injectors, cylinder heads, liner and piston groups, crankshafts, overhaul kits.
• Transmission and torque converter: mechanical transmission components, planetary gear sets (the 794 AC, 796 AC and 798 AC use an electric drive instead: generator, AC traction motors, power electronics, retarding grids).
• Rear axle and final drives: differentials, planetary reduction units, wheel-end assemblies.
• Brake system: discs, pistons, pumps and valves.
• Suspension and steering: suspension cylinders, steering cylinders.
• Hydraulics: pumps, body-hoist cylinders, control valves.
• Electronics and sensors: engine and transmission control units, sensors, harnesses.
• Cooling system: radiators, fan drives.

These are the main groups that account for most orders. If your item is not listed, send us a request and we will check it against the catalog.

Stock availability and lead times

We keep a large range of fast-moving items for these models in stock, and they ship in the shortest possible time. It is not possible to stock the entire Cat parts range, so some items are supplied to order. For such items, the lead time must be confirmed; we provide it once the part number is verified.

To avoid downtime, order with planned maintenance in mind, and submit requests for critical assemblies in advance.
