AGT's live shop uses QDL-H12 for two different products: a drive sprocket and a grease track-tensioner assembly. — Use the product URL, component description and drawing/measurements as well as the code. This observation is not a claim that either item fits these exact models.
Unverified details (2)
  • No evidence establishing UHI/Rhinoceros/Hightop OEM identity.
  • Manual includes mixed-engine boilerplate; verify service instructions against fitted engine.

Confirm the machine plate, market, build year and fitted engine before using a parts or service reference.
