Fitment compatibility, stock status, and international shipping terms are confirmed for every order.
How do you guarantee that all engines and spare parts are 100% genuine?
We supply 100% genuine original equipment and replacement parts. Prior to balance payment and shipment, we provide high-resolution warehouse photos and videos of the original factory packaging, hologram security labels, part markings, and engine serial numbers for your verification.
How can I check stock availability and delivery lead time?
Stock status and dispatch lead time depend on the specific part number or engine configuration and your destination port. Exact availability and shipping schedules are confirmed in our commercial quotation.
What details do you need to verify spare part fitment?
Please provide the exact factory part number (P/N). If you do not have the part number, send a clear photo of the engine nameplate and the engine serial number (S/N) so our engineers can cross-reference it in CAT SIS or Perkins SPI.
Do you supply individual consumers or only B2B industrial clients?
We specialize in B2B export supply for industrial projects, mining and construction fleets, power plants, and equipment maintenance companies worldwide. Please include your company details when submitting an RFQ.
Can you replace an existing engine with an equivalent assembly?
Yes, subject to engineering verification. Before quoting a replacement engine, our team checks flywheel housing SAE size, cooling system arrangement, mounting footprint, and electronic control interface.
