Yokomo YOKSG-A4884 - DCS 84T Spur Gear (DP48)  [YOKSG-A4884]

DCS 84T Spur Gear for DP48

The Yokomo YOKSG-A4884 DCS 84T spur gear is an RC-scale replacement part intended for DP48 drivetrain configurations. It serves as the large spur in the reduction train and is used where a specific 84-tooth count is required to set the vehicle's final drive ratio.

This component's role is strictly mechanical within the model's gearbox: it interfaces with the motor pinion and other drivetrain elements to define acceleration response and top-speed balance. When swapping spur gears, confirm that the gear seats and shaft alignments match the DP48 layout before final assembly.

Installation notes: mount the spur gear on the designated output shaft, secure any retaining hardware specified by your chassis, and rotate the drivetrain by hand to check for smooth engagement. Adjust gear mesh until rotation is free of binding while avoiding excessive play that can accelerate wear.

Tuning and maintenance: changing to an 84T spur alters the gear ratio compared with smaller or larger spurs, so expect corresponding changes in throttle feel and effective gearing. Regularly inspect tooth profiles for chips or wear, keep mating surfaces clean, and verify compatible pinion dimensions to maintain consistent mesh.
