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

Spur replacement for TT-01 drivetrains

This 42 pitch, 62T Delrin spur gear is supplied as an aftermarket replacement compatible with Tamiya TT-01 platforms, intended for builders who need a low-friction, dimensionally stable gear for drivetrain tuning. It is suitable for standard 42 pitch arrangements found on TT-01 kits and related chassis.

Delrin (acetal) is used for its consistent shape retention and low surface friction, helping to cut drivetrain drag and deliver smoother tooth engagement versus some common plastics. Choose it when accurate mesh and gentle tooth contact are required for setup changes or routine servicing.

Fitment tips: verify the spur pitch and tooth count match your pinion and gearbox, establish the correct mesh using a thin shim or conventional method, then spin the drivetrain and check for binding. Inspect bearings and gearbox for excessive play to avoid early tooth wear.

Tuning application: this spur aids steady tooth engagement under load and supports fine tuning of gear ratios alongside matching pinions to balance acceleration and top speed for track outings or practice sessions.
