Disassemble the Core Power Assembly of Tire Changers: Motor & Reducer Assembly Craftsmanship Determines 10-Year Service

Motor and reducer are recognized as the "heart" of tire changers, yet most equipment manufacturers simplify assembly procedures to cut costs, leading to gear jumping, motor stuffy noise and power attenuation after short-term use.

Roadbaker implements standardized assembly processes for power assemblies on all tire changer models including V9120, V7110 and GT525 series. Special tooling is used to steadily lift the reducer during installation to avoid knocking that causes hidden cracks on the aluminum shell. The offset of the central shaft after assembly must be less than 1mm.

When installing the drive motor, all fastening screws are tightened with a fixed torque of 40N·m to ensure full fastening without loose gaps. After assembly, the power unit undergoes simulated working cycle tests: forward rotation, reverse rotation and shutdown repeated 20 times continuously. Only units with no abnormal gear collision and no dull motor sound can pass inspection.

All series adopt rear-tilting main column design, supporting maximum 24/26-inch wheel hubs, equipped with central shaft locking device to prevent hub scratches. The pneumatic flipping mounting head cancels manual crowbar operation, effectively avoiding rim damage.

Strict power assembly inspection can eliminate hidden dangers such as insufficient tire peeling force and turntable stalling. Roadbaker’s 20 years of production experience focuses on refining every assembly detail, making each tire changer stable and durable for long-term workshop high-intensity operation.
