Technical Specifications

Key Features

• Complete assembly. Engine block, cylinder head, turbocharger and aftercooler fitted, supplied as one unit to shorten installation time.
• 133 kW rating confirmed on the test bench. Each engine is run and checked for power output, oil pressure and coolant circulation before packing.
• Configuration matched before shipment. Flywheel housing, starter and alternator position, fan drive and exhaust outlet are confirmed against your machine, so the engine does not arrive as a near fit.
• Parts support. We also supply cylinder heads, turbochargers, water pumps, gasket sets and injectors for the same engine family, so follow-up service parts ship from one supplier.
• Factory direct supply. Sourced and inspected in Guangdong, with stock available for urgent breakdown orders.

Fitment Notes

Please confirm your machine model, serial number and the engine number on the existing nameplate before ordering – the same 5.9 litre engine family is built in several configurations for different machines, with differences in flywheel housing, governor, emissions set-up and accessory drive. Send us photos of the engine nameplate and the machine, and our team will confirm the configuration within 24 hours.

FAQ by Market

Q1: North America & Europe – what do I need to send before you quote?
Send photos of the engine nameplate, the machine model and serial number, and the flywheel housing side of the engine. We confirm the configuration and power rating within 24 hours, and can supply dimension drawings for approval before shipment.

Q2: European Union – what documents come with the shipment?
Each order ships with commercial invoice, packing list and a technical datasheet for customs clearance. Tell us if your market requires additional documents for engines and we will confirm what we can provide for your order.

Q3: Middle East & Africa – how does the engine handle heat and dust?
For high ambient temperature and dust, we recommend the correct coolant mix, a clean air filter element and a radiator flush before installation. Ask us for the oil grade and service interval recommendation for your climate, and we can quote a filter kit with the engine.

Q4: Southeast & South Asia – what is the minimum order and how do we talk price?
Minimum order is 1 unit and the price is negotiable – it depends on quantity, shipping mode and whether you consolidate the engine with other parts in one shipment. Send your target quantity and we will quote accordingly.

Q5: Russia & CIS – can it start in low temperature?
Yes, with the correct oil grade and a working pre-heat system. Tell us your winter ambient temperature and we will recommend the oil grade and cold-start procedure, and can quote a low-temperature coolant and heater option on request.

Q6: South America & Australia – lead time and after-sales?
Delivery is normally 15–30 days after order confirmation, and warranty terms and claim procedure are agreed with your sales contact before shipment, including how to submit photos or video of the engine running for assessment.
