Doosan machines in the extract are the DX generation — DX225 through DX520 — and the demand pattern is travel and swing: the components that carry ground pressure and rotation wear first. The swing bearing page documents the DX225 slewing ring that pairs with the DX225 swing motors below, and the final drive and travel motor pages carry the full drive-line context.

Notes for Doosan Buyers
- Suffix letters matter. Several listings differ only in the final letter (00048 / 00048A / 00048B) — quote the number character-for-character.
- Motor or drive? Two rows above are combined or alternative assemblies; the reply states which unit the number covers before you pay.
- Swing pairs. If the DX225 needs both motor and bearing work, say so — the two are quoted together with the pinion checked between 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
Are these parts made by Doosan?
No — and this page does not pretend otherwise. Kyotechs is an independent aftermarket supplier; the parts listed are compatible with Doosan machines. Each listing states its own specification and condition, and the enquiry reply confirms exactly what will ship.
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.
Doosan Range Notes
The Doosan extract is a study in why full numbers matter. The DX300 travel listings alone carry three closely related number groups (00048, 00048A, 00048B, plus 170402-00009) recorded against overlapping model lists — DX300, DX300LC, DX300LCA, DH300. These are not clerical duplicates: suffixes separate production variants, and fitting the wrong variant is a freight-expensive mistake. Quote the number character-for-character from the unit's plate; if the plate is worn, the machine's serial number and a photograph of the unit's ports and mounting are the fallback identifiers the reply will work from. The same care applies to the DX500 final drive, whose listing carries four recorded numbers for one assembly.
Freight planning is worth a sentence on this brand page: travel and final-drive assemblies are among the heaviest lines in the catalogue, and Doosan's larger models carry the heaviest of them. The enquiry reply includes packing and shipping options as standard (export packing is the documented default), and buyers consolidating several heavy lines into one shipment should say so in the first message — consolidated freight on documented listings is where a multi-line Doosan order recovers real money.
