The engine side of Kyotechs' catalogue has two levels: complete engine assemblies (the official catalogue lists them for Hyundai and Kubota machines, among others) and the component parts below. The documented extract concentrates on the rotating and top-end hardware that engine rebuilders order most — crankshafts above all — plus the sensors that feed the controller. Engine parts are matched to the engine model named in each row, which may serve several machine brands.

Assemblies and the Repair Route
Where an engine is beyond component repair, the documented assemblies include the Hyundai S4K R140-7 assembly (11N3-00010), the Hyundai R210-9S assembly (11Q7-01010) and Kubota V3300 and V2403BM assemblies. And where the engine is worth saving, the engine repair solution starts with diagnostics — five diagnostic platforms are documented there — before any parts are sold. Fuel system components have their own pages: fuel injectors and turbochargers.
- Engine model and serial number from the engine nameplate — not just the machine model.
- Part number for the component, or the assembly number for a complete engine.
- What the rebuild actually needs: a crankshaft order often travels with bearings and seals; say if you want the mating parts checked too.
Delivery and preparation times are confirmed for your order in the enquiry reply, in writing and before payment: the reply states the times, the packing and the shipping method that apply to your exact part number. Times are confirmed per order rather than published as a general figure, because they follow the listing, the quantity and the destination.
Frequently Asked Questions
Why is the engine model more important than the machine model?
The same machine can carry different engines across markets and years, and one engine serves many machines. The engine nameplate settles questions the machine badge cannot.
Do you sell complete engines?
Engine assemblies are documented listings — Hyundai and Kubota assemblies appear in the extract, and Isuzu engine assemblies are documented Alibaba listings. Each is confirmed by assembly number in the enquiry reply.
Do the parts carry a warranty?
Warranty terms are confirmed in writing for each order before payment. Kyotechs' own FAQ states that most parts are backed by a warranty against manufacturing defects; ask for the term that applies to your listing when you enquire.
Matching Engine Parts to the Engine, Not the Badge
The listings above repeat one lesson in several forms: two crankshafts are recorded against Isuzu and Hino engines fitted in Hitachi machines, and one sensor serves five Caterpillar models. Engine parts follow the engine. When you enquire, the engine nameplate — model, serial number, and any arrangement number — is worth more than a photograph of the machine. If the plate is missing, casting numbers on the old component are the fallback, and the reply will work from those. Rebuilds also travel in sets: a crankshaft typically needs bearings and seals, a head needs its gasket set — say if you want the mating parts checked and quoted with the main component.
