Unverified details (1)
Factory page lists U18 and U20 with shared/combined specifications; the U18 product page and older factory brochure differ on track/weight and rated-power observations. A factory manual index names both U18 and U20, but their current direct download links returned 404. The factory filter/wear parts routes are inquiry pages rather than a public illustrated parts book. Match serial and installed configuration before parts/service.
Confirm the machine plate, market, build year and fitted engine before using a parts or service reference.

Relationship labels keep confirmed rebadges separate from shared components and lookalike search leads. Verify the model plate, market and serial before ordering parts.
No source-backed direct model relationship is recorded yet.
Yuchai U18 has its own searchable manufacturer record. No evidence establishes a UME10T rebadge, shared OEM platform or whole-machine/parts interchange.
Evidence scope: Compact-excavator discovery lead only; check model, market, serial, engine, track gauge, undercarriage and attachment dimensions.
Whole-machine interchangeability is not established.

How to use this model file
Source names, publishers, editions and check dates stay on the page so you can judge the evidence without jumping between product sites. A relationship is only treated as a rebadge when the underlying sources explicitly support that scope.
