DP48 spur function and installation pointers

The 82-tooth DCS spur is intended for DP48-style applications and supplied as a direct replacement for spur assemblies. It is useful for restoring proper mesh, swapping gear ratios, or replacing a fatigued spur in RC touring drivetrains.

Installation follows standard DP48 gearbox procedures: set centre mesh, verify pinion backlash, and fasten the spur using the original retention method. Conduct a measured run-in and check that the assembly rotates smoothly under load before finalising setup.

Tuning guidance: changing to an 82T spur alters gear ratios and can shift the balance between acceleration and top speed depending on motor and pinion choices. After any spur change, recheck alignment, bearing condition, and layshaft freedom to prevent premature wear.

  • Tip: After fitting, rotate the drivetrain by hand to ensure free movement, then test at low throttle to confirm clearance.
  • Tip: Combine the 82T spur with compatible pinion counts to achieve the gearing you need without overstressing the motor.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What checks should I do before fitting the spur?

Confirm spur hub fit, measure centre spacing, and inspect the pinion and bearings. Ensuring these items are correct makes installation straightforward.

Can I use this with high-power brushless motors?

Yes, but check that your chosen pinion and final ratio do not exceed motor limits and that bearings and shafts are in good condition to handle increased loads.

How do I tune gearing with an 82T spur?

Adjust pinion tooth count to alter final ratio. Smaller pinions raise top speed while larger pinions improve acceleration; try incremental changes and test lap performance.
