47T M1.0 Spur for ARRMA 1/5 drivetrains

This spare spur is manufactured to match the factory 47T, module 1.0 profile used on ARRMA 1/5 Kraton and Outcast platforms, while employing 20CrMnTi steel to increase wear and fatigue resistance under heavy RC demands. It functions as a direct replacement or an upgrade for enhanced drivetrain longevity in both RTR and EXB setups.

Fitment tips: clean the gearbox before fitting, confirm the motor pinion uses module 1.0 pitch and the correct tooth count, and set backlash during assembly. Keep original shims where practical and avoid overtightening screws to prevent bearing preload and binding.

Setup impact: installing a higher-strength steel spur lowers the risk of premature tooth wear when using powerful brushless motors; it does not change the drive ratio if you keep the same 47T, so focus tuning on pinion sizing and slipper/clutch adjustments.

Will this change how I should set the slipper or clutch?

Switching to a stronger steel spur does not directly alter slipper or clutch settings, but you may find slight changes in load feel; retune the slipper or clutch to match your motor and driving style after installation.

Do I need to alter ESC calibration?

No specific ESC recalibration is required just for the spur swap; however, if you change pinion size or motor power, revisit throttle and brake settings to maintain control.

How precise should gear mesh be set?

Set gear mesh to a small running clearance that removes play without causing binding. Recheck after a short break-in run and adjust shims if required.

Is lubrication recommended?

Light lubrication on the gear teeth is optional; focus on keeping contaminants out of the gearbox and inspecting teeth after gritty conditions.

What signs indicate replacement is needed?

Look for scalloping, chipped teeth, or unusual noise under load; replace the spur if any of these appear to avoid further drivetrain damage.
