ENDURO SENDERO TRAIL TRUCK Aftermarket 87T Spur Gear Hardened Steel #45 - ES087TS by GPM  [ES087TS]

Scale spur gear for ENDURO SENDERO

This 87T spur gear serves as a direct-fit replacement for the ENDURO SENDERO TRAIL TRUCK drivetrain and is supplied as a single part to mount beside the motor gear. It is aimed at replacing damaged or worn spurs to restore steady torque transfer for trail running.

Material and role: using hardened steel #45 increases toughness and extends wear life relative to stock plastic components, while maintaining the original tooth count and overall gearing characteristics.

Installation and tuning notes: install onto the standard spur shaft and verify correct mesh with the motor pinion (摩打齒). Inspect the contact pattern across the teeth and adjust shims to reduce backlash where needed. Ensure secure mounting to avoid slippage during use.
