MIDDLE SHAFT PULLEY HTD-8M-51 PRIMARY DRIVE PULLEY FOR LBX AND SEGWAY
Middle shaft pulley HTD-8M-51, also known as the primary or jackshaft drive pulley for the Surron Light Bee (LBX) and equivalent Segway models, is a robust HTD-8M timing pulley designed with 51 teeth and compatible with the standard 8?mm pitch belt system used in these e-bikes.
Features
- Compatible with HTD 8M timing belts—features the high-torque drive (HTD) tooth profile for precise, efficient power transmission and reduced backlash
- OEM-style primary drive pulley for the Surron LBX and Segway jackshaft/motor assembly
- Visible wear or sharp edges on this pulley may indicate replacement is due—worn belts can reflect pulley deterioration
- Likely constructed from aluminium or steel with a spoked or web-design structure, similar to other HTD-8M pulleys used in varied industrial applications
Specifications
- Tooth pitch: 8?mm (HTD-8M profile)
- Number of teeth: 51 (as indicated by “51” in the part designation).
- Constructed potentially in a spoked or web-style design, like typical HTD-8M pulleys—with possible flange depending on exact OEM design
- Material: Typically steel or aluminium (common for timing pulleys, though OEM exact spec not confirmed)
- Bore/fixing: Likely pilot-bore or taper-lock configuration suitable for fitting onto the motor jackshaft—specific dimensions not publicly specified but consistent with industrial HTD-8M form factors
Vehicle Fitments
- Surron LBX (Light Bee)
- Equivalent Segway electric dirt bike models
