Tamiya TT-01 42 Pitch 62T Delrin Spur Gear DTT4262T by GPM  [DTT4262T]

Technical replacement spur for TT-01

This 42 pitch, 62T spur is produced in Delrin for Tamiya TT-01 drivetrains as a precision aftermarket replacement, intended for hobbyists and tuners seeking consistent mesh and reduced friction. The design matches common 42 pitch layouts used on TT-01 kits and similar configurations.

Delrin (acetal) is selected for dimensional stability and low surface friction, supporting smoother tooth engagement and reduced drivetrain drag when bearings and shafts are within tolerance. Use this spur when precise mesh and repeatable setup changes are required.

Fitment and setup recommendations: confirm 42 pitch compatibility and correct tooth count, set gear mesh with the standard shim or feeler method, then rotate the drivetrain fully to identify any binding points. Verify bearing clearance and gearbox tolerances to protect gear teeth and ensure long service life.

Tuning note: the 62T Delrin spur aids steady tooth engagement under load and enables fine adjustments to acceleration and top speed when paired with appropriate pinions during track setup or practice sessions.
