When an excavator loses its engine, the machine stops earning, and the quickest way back into production is usually a complete replacement rather than a strip-down rebuild on the workshop floor. This is a finished diesel engine motor unit for machines built around the four Volvo engine codes listed in the specification table below — the old engine comes out, the replacement goes in. Owners book this kind of swap between jobs so the machine is not standing open in the yard. Repair workshops keep one on the shelf so a customer is not waiting while parts arrive. Distributors hold one for mixed fleets where several engine codes are in daily service. As an excavator parts supplier, we crate each engine ready for installation and send the paperwork your technician needs to check what has arrived before the housing goes back on.

The four engine codes covered here are separate build designations, and one should not be treated as a straight swap for another. Two machines from the same series can leave the factory with different engine arrangements, so the deciding information sits on your own engine rather than on the badge on the counterweight. Start with the engine data plate, which carries the engine model and serial number — those are the two values we match against when your order is prepared. If the plate is missing, corroded or the machine has been re-powered at some point, photographs of the engine bay and of the machine identification plate are the next most reliable reference. Every engine assembly is checked against the machine it is going into before it is crated, and where a listing does not suit your unit we will say so rather than ship something your workshop has to make fit.
Our technical team supports buyers before and after the order. Send us your OEM part number or machine and engine details and we will confirm the correct match for your repair, overhaul or replacement job. If you are unsure what has failed, share the symptoms and our specialists will help with troubleshooting and narrow down the right assembly. We also provide installation and commissioning guidance, and share product documentation on request. With coverage across Komatsu, Caterpillar, Cummins, Isuzu, Hitachi, Sany, Doosan and Kubota machinery, we can help consolidate your parts requirements into one order.
Work through the machine's service manual first: fill with the specified oil and coolant, prime the fuel system before the first crank, and check the filters, pipework and drain plugs for leaks once it fires. Run it at light load and watch oil pressure and temperature before returning the machine to full production.
Change the oil and filters at the first interval your manual lists for a replacement engine, then re-check mounting bolts, hoses and pipework for tightness. During the first weeks, watch coolant level, exhaust colour and oil pressure. After that, the engine follows the same service schedule as the unit it replaced.
It is listed for excavator use. If the machine is a wheel loader, drill rig or generator set that carries one of the four engine codes, send the plate details and we will confirm whether this assembly applies before you commit to an order.
As a diesel engine parts supplier, we provide a machinery test report with each unit and an outgoing inspection video so you can see the engine before it is loaded. Ask for both with your quotation documents so your technician can review them ahead of the delivery.
The parts that are easiest to reach while the engine is out are the ones worth planning: coolant hoses, belts, filters, fresh coolant and oil, plus any tired mounting cushions or cracked pipework. Send the list with your enquiry and we will quote the engine components together with the engine.
Leave it in its crate until the bay is free, keep it under cover and off damp ground, and leave the sealing plugs and caps in place until installation day. If the engine will stand for several months, tell us and we will confirm what your workshop should check before starting it.
