The Yokomo C-CQ0223A spur is a replacement component for HL-150 series platforms that use a slipper drive. It has 85 teeth at a 48 pitch specification and is intended for drivetrain servicing and ratio adjustments on CE-HL150 1/10 4WD RTR trucks.
Fitment and role: tooth count and 48P pitch determine correct engagement with the matching pinion and the slipper mechanism. Confirm pinion pitch and slipper hub clearance before fitting. Use this part to replace worn gears or when changing final drive ratios for different driving conditions.
Installation notes: confirm correct backlash against the mating pinion, inspect the slipper clutch assembly for wear prior to reuse, and ensure the spur is mounted square to the gearbox output to avoid binding. Tighten screws to specified torque and verify smooth rotation at the bearings before first powered tests.
