How we supply these parts

Parts for the Caterpillar articulated dump truck range: 725, 725C, 730, 730C, 735, 740, 740B, 745 and their earlier equivalents. We cover driveline and transmission internals, torque converters, differentials, drive shafts, wet brakes and brake discs, hoist and steering cylinders, suspension and oscillation joints, body liners and tailgates, plus the full engine, cooling, electrical and cab fittings.

Application & fitment

Fitment is confirmed from your machine model and serial range before anything is quoted.

Sourcing & grades

Genuine, OEM-equivalent and premium aftermarket quoted side by side — you choose.

Delivery & export

Air freight, express and sea freight with crating, weights and documents prepared by our export desk.

Quality control

Incoming inspection and dimensional checks against the original part number, photo confirmation before dispatch.

Kits & combined orders

Complete assembly kits and mixed orders with other machines to cut freight per unit.

After-sales

Fitment support, replacement on confirmed quality issues and paperwork for warranty claims.

Fitment and sourcing notes

Articulated trucks run in mud, gradients and continuous haul cycles, so the consumable list matters: brake discs, brake packs, drive shaft joints, suspension bushes, hoist cylinder seal kits, hoist valves, filters and cab glass. We quote these as scheduled kits so you can plan maintenance around production.

Provide the model, serial number prefix and the part number or photo of the worn component, and we will confirm availability with grade options and freight.

FAQ

Do you supply complete brake kits for the 740B?
Yes. Front and rear wet brake disc and plate sets, seals and piston kits are quoted as complete axle-end kits.
How do you handle parts for older D-series articulated trucks?
D250E, D300E, D350E and D400E parts are cross-referenced to their current Caterpillar equivalent number where the part has been superseded.
Can you supply body liners cut to size?
Body liner plates can be supplied to original dimensions, or cut and formed to a drawing if you provide a template.
What is the typical lead time?
Brake, filter and seal items usually ship same-day from stock; transmission and driveline components take 2–5 working days to confirm and dispatch.
Can you supply driveline parts in kit form for planned shutdowns?
Yes — we build shutdown kits around your maintenance schedule so every part arrives at one time in one shipment.
