XCMG 3-Ton Loader Gearbox Bracket – PN 252700220 / 350K.2.4 | OEM Transmission Mount Support

The XCMG PN 252700220​ (drawing 350K.2.4) is the gearbox bracket​ in XCMG wheel loaders — public-channel data lists it under loader transmission spares, while one low-authority channel narrows it to the 3-ton loader​ family— confirm the exact machine against the BOM. Its job is to securely fix the gearbox to the frame, taking on three duties: support, positioning and vibration isolation​ — carrying the gearbox's own weight plus part of the powertrain load, while cushioning engine-transmission driveline vibration through elastic mounts to reduce transmission into the frame and cab. XCMG heavy-machinery patents show this class of bracket typically consists of a first bracket connected to the frame, a second bracket connected to the gearbox, and an intermediate connecting/elastic element, with the support face often angled to boost vertical isolation and horizontal-load resistance.
