A travel motor fault is usually one-sided: the machine tracks crooked, one side is slow, or drive disappears entirely on one track. Diagnosis starts by swapping the hoses or testing pressures to separate motor from gearbox and both from the pump — the final drive page covers the gearbox assemblies in depth. This page holds the motor and combined listings documented in Kyotechs' catalogue.

Motor, Gearbox or Both?
If the track turns but weakly under load, suspect pressures and the motor. If the track is locked, noisy or leaking gear oil at the sprocket, suspect the gearbox. For the motor, a repair route exists: the hydraulic repair solution names travel motors among the components it refits, rebuilds and tests — a rebuilt motor is bench-tested and supplied with a test video before it goes back on the machine. The gearbox is a separate assembly: it is quoted as a replacement by its documented number (see the final drive listings), not as a repair item.
- Part number from the motor plate, machine model, and which side is affected.
- Whether the sprocket turns at all, and any leakage at the motor or the drive.
- A photo of the motor and its ports if the plate is unreadable — port layout separates look-alike motors.
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
Do travel motors come with the gearbox?
Some documented listings are motor-only, some are gearboxes, and some are combined units — each row above says which. The enquiry reply confirms the scope of the exact number before payment.
Can my old travel motor be rebuilt?
Travel motors are one of the named component groups in the hydraulic repair solution. The process is inspection first, then a rebuild quote — the unit is tested and videoed before return.
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.
Travel Diagnosis: Separating Motor from Drive
Before any travel component is ordered, one test saves more money than any other: swap the main hoses between the two travel motors (or compare pressures side to side). If the fault follows the hoses, the problem is upstream — pump or valve. If it stays with the side, it is in that side's motor or gearbox. Leakage location refines it further: hydraulic oil at the motor points to motor seals; gear oil at the sprocket points to the final drive's floating seal. The documented listings on this page are quoted against that evidence, and the repair service will assess a motor that tests as repairable instead of selling a replacement by default.
