Delrin spur gear option for TT01 drivetrains

This Delrin 42-pitch 61-tooth spur gear, referenced as DTT4261T, is offered as an aftermarket replacement for TAMIYA TT01 transmissions. It is intended for routine spares, maintenance swaps, or simple gearing changes to tune performance.

Confirm your chassis uses 42-pitch gears before fitting and set pinion mesh carefully to avoid backlash or binding. Recheck the spur hub and related bearings when servicing to ensure correct fitment and longevity.

A 61T spur changes final drive characteristics, often trading a bit of top speed for improved acceleration. Delrin is chosen for its lower friction and quieter running compared with some other materials.

Do I need special tools to fit this spur?

No special tools are required beyond standard gearbox disassembly tools; ensure correct torque on the spur hub and verify mesh afterward.

Is shim adjustment necessary?

Yes, shimming the pinion or adjusting the spur position may be needed to achieve a light, consistent mesh with no binding.

How often should I inspect the teeth?

Inspect teeth and mating pinion periodically, especially after heavy runs or impacts, to catch wear or damage early.
