An excavator's hydraulic system is a chain: pump, control valve, motors and cylinders, sealed at every joint. Kyotechs' catalogue is organised the same way, and its Alibaba store groups the range under pump, travel motor, travel gearbox, swing motor, swing gearbox, control valve, hydraulic cylinder, slewing bearing, solenoid valve, repair parts and seals. The family pages below mirror that structure, each with the documented part numbers on record.

Hydraulic parts are also where the repair service earns its keep: pumps, travel motors, swing motors and main control valves are the four component groups named in the hydraulic repair solution, which refits, rebuilds and tests units instead of only replacing them.
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
I know the failed function but not the part. Can you help identify it?
Yes — describe the symptom and the machine model. One weak function usually isolates the valve, motor or cylinder involved, and the reply will name the documented listings that fit before you commit to a number.
Are hydraulic parts sold new or used?
Both appear in the documented catalogue; every listing states its condition. Rebuilt units from the repair service are tested before dispatch and supplied with a test video.
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.
How the Families Connect
Buyers often arrive with a symptom, not a family name. Weak travel on one side lives in the travel motor or final drive; a drifting boom lives in the control valve or the cylinder seals; slow swing lives in the swing motor or its brake. The index above is arranged so each symptom has a page: start from the function that fails, read the family's documented listings, and use the linked pages to check the neighbouring component before ordering. Hydraulic faults punish parts-swapping — two components in the same chain wear together, and replacing the wrong one buys the same fault twice. The family pages are written to separate those cases, and the repair service exists for the components where inspection must come before any sale.
