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

TT-01 spur gear replacement

This 42 pitch 62T spur gear is molded in Delrin for use on Tamiya TT-01 drivetrains, supplied as an aftermarket replacement for hobbyists seeking a durable, low-friction option. It is intended for 42 pitch systems commonly fitted to TT-01 kits and TT-01 based layouts.

Delrin (acetal) is selected for its dimensional stability and low surface friction, which helps reduce drivetrain drag and improves tooth engagement compared with some standard plastics. Use this material where consistent mesh and gentle tooth contact are important during tuning and maintenance.

Installation notes: confirm the spur is 42 pitch and 62T to match your pinion and gearbox, set gear mesh with a thin shim or standard mesh method, then rotate the drivetrain to check for any binding. Also inspect bearings and shaft play to avoid premature wear on the new gear.

Tuning role: this spur gear supports stable tooth engagement under load and lets you fine tune gear ratios by pairing it with compatible pinions to adjust acceleration and top speed for practice laps or casual track runs.
