Tamiya TT01 42 Pitch Delrin Spur Gear by GPM DTT4262T  [DTT4262T]

Spur gear for TT-01 drivetrains

This Delrin 42 pitch 62T spur gear is an RC-scale replacement part produced for the Tamiya TT01 platform by GPM, offered as an option for hobbyists who need a durable, low-friction gear for drivetrain tuning. The part is intended to work with 42 pitch systems commonly used on TT-01 kits and similar TT-01-derived layouts.

Delrin (acetal) is chosen for its dimensional stability and low surface friction, which can help reduce drivetrain drag and contribute to smoother gear engagement compared with some standard plastics. Use it where consistent gear mesh and gentle tooth contact matter, such as during setup changes, gear ratio experiments, or routine maintenance.

Installation notes: verify the gear pitch and tooth count match your existing pinion and gearbox, set a correct gear mesh using a thin shim or a standard mesh technique, and check for binding across the rotation range after installing. Inspect surrounding bearings and the gearbox for play to avoid premature wear on the new spur gear.

Practical tuning role: this spur gear is a hop-up that helps maintain stable tooth engagement under load and supports fine-tuning of gear ratios when paired with compatible pinion gears, helping you dial-in acceleration and top speed for track or practice sessions.
