This 87T spur gear is an RC-scale replacement designed for the ENDURO SENDERO TRAIL TRUCK drivetrain and is supplied as a single spare for the spur position adjacent to the motor gear. It replaces worn or damaged stock spurs to help retain consistent power transfer during scale and trail use.
Material and role: produced from hardened steel #45 for improved toughness and longer wear life compared with common plastic gears, this spur retains original tooth count and gearing while increasing reliability under stress.
Installation and tuning notes: mount on the standard spur shaft and check mesh with the motor pinion (摩打齒), confirm smooth tooth engagement across the face, and apply shims where necessary to manage backlash. Always ensure the gear is fastened securely to prevent drivetrain slippage while running.
Includes: Spur Gear 1pcs
