Fit and installation notes for Tamiya TT02 70T Delrin spur

This Delrin spur gear is a scale RC replacement intended for the Tamiya TT02 platform and TT02B variant, supplied as 1pcs and specified as 42 pitch, 70T. It is an aftermarket gear for hobby drivetrain use only and is not for real vehicle applications.

Delrin material offers low friction and dimensional stability suited for spur gear use in RC drivetrains. When replacing the stock gear, check existing pinion alignment and ensure the gearbox is clean; confirm gear mesh and bearing condition before running the model. Use common RC practice to set mesh and secure the gear to avoid slippage under load.

For tuning, this 70T spur alters the final drive compared with other common tooth counts used on TT02 setups, so pair it with a suitable pinion to match your motor and ESC. The part is intended as a direct fit for the listed chassis when used with the original gearbox components.

How should I set gear mesh when fitting the 70T spur?

Start with a small layer of paper between pinion and spur, tighten the spur in place, then remove the paper to confirm a slight running clearance. Recheck after a short run as components bed in.

Can I reuse the stock hardware when replacing the spur?

Yes, use the original screws and spacers if they are undamaged. Inspect the mounting screw and set-screw for wear and replace if any rounding or damage is present.

Any quick checks to avoid gear slippage?

Verify the pinion is tight on the motor shaft, ensure bearing play is minimal, and confirm the spur is secured to the gearbox hub with the correct torque on the fixing hardware.
