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

Aftermarket 42 pitch spur for TT-01

This Delrin 62T spur gear is produced as an aftermarket option for Tamiya TT-01 drivetrains, aimed at modelers wanting a tougher, lower-friction replacement. It fits standard 42 pitch configurations used in TT-01 kits and similar derivative layouts.

Delrin, an acetal polymer, is chosen for steady dimensions and a low-friction surface that can reduce drivetrain drag and promote smoother tooth engagement compared with some generic plastics. It is recommended where consistent gear mesh and gentle contact are needed during setup or ratio testing.

Installation guidance: confirm the gear pitch and tooth count match your pinion and gearbox, set an accurate mesh with a thin shim or the usual mesh method, and test-rotate the drivetrain to check for binding. Inspect bearings and gearbox tolerances to prevent premature wear of the new spur.

Use case: the spur helps preserve stable engagement under load and lets you fine tune acceleration and top speed by pairing it with matching pinions for track or practice sessions.
