The official catalogue lists Undercarriage Parts as one of its fifteen categories, alongside separate categories for Travel Motor & Gearbox and Swing Motor & Gearbox. This page is the index to the powered components Kyotechs documents across those parallel lines: the travel device (final drive) at each sprocket, the travel motors and gearboxes, and the swing motors, gearboxes and bearings. Those components have their own pages with documented part numbers.
What Is Not in the Documented Range
This site does not invent catalogue breadth. Track chains, track shoes, rollers and idlers are not in Kyotechs' documented product extract, so they are not listed here as stocked lines. If you need them, ask in the enquiry — the answer will distinguish what the documented catalogue covers from what can be sourced on request, rather than presenting either as the other. That distinction is the whole point of ordering by documented part number.
Ordering Undercarriage Drive Parts
- Part number and machine model, plus the side (left/right) for travel components.
- The failure mode — no drive, noise, leakage, play — which separates motor, gearbox and bearing faults.
- Gear oil evidence: metallic debris on the magnetic plug is decisive information for a final drive quote.
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 you sell track chains and rollers?
They are not in the documented catalogue extract this site is built from, so they are not presented as stocked lines. Ask by part number and the reply will state plainly whether the item can be supplied.
Which undercarriage parts fail most often?
In the documented range, final drives — usually through gear-oil neglect — and swing components. The family pages describe the failure patterns and the checks that separate them.
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.
Undercarriage Economics
Undercarriage work is where machine value concentrates: the drive components in the documented range are the parts that stop a machine earning when they fail, and they fail on maintenance more than on hours. Gear oil discipline in final drives, grease discipline in swing bearings, and early attention to leaks are worth more than any single purchase. When a drive component does fail, the buying discipline of this site applies in full — part number, side, failure evidence — because undercarriage freight is heavy and a wrong unit is expensive in both directions. The family pages linked above carry the documented listings and the failure patterns for each component.
Measurement beats opinion in this category as well. Remaining gear tooth profile on a final drive's sprocket interface, play in a swing bearing measured with a dial gauge, and oil condition from a drain sample are all numbers that can travel in an enquiry and be answered against the documented listings. Buyers who build the habit of measuring before ordering find that undercarriage quotes get faster and more accurate with every machine they maintain.
