GPM Racing Steel Large Bevel Gear - 2pcs (For TT02 / Tt02b) for Tamiya TT02 (TT2100/G3)

Precision steel bevel for TT02 gearboxes

This is a hardened steel large bevel gear sold as a two piece set for installation in Tamiya TT02 and TT02B 1/10 scale gearboxes. The design is intended as an aftermarket replacement where increased wear resistance is required without altering basic gearbox geometry.

Within the TT02 gearbox the large bevel gear transmits torque from the pinion and spur train into the differential assembly and wheels; selecting steel alters contact characteristics and service life. During installation follow TT02 service procedures, verify accurate mesh with the mating pinion, assess bearing condition, and apply appropriate lubricant to both the differential and gear faces prior to operation.

Use this set for scheduled maintenance or measured durability upgrades, and address any worn bearings or misalignment to avoid accelerated wear on plastic mating parts when introducing steel components.

What checks should I perform before fitting TT2100/G3?

Confirm bearing play is minimal, inspect pinion and spur for wear, and ensure housing faces are clean. Proper base condition is important before fitting hardened steel to avoid accelerated wear.

Recommended lubrication and mesh practice?

Set a precise mesh with the pinion, use a thin layer of suitable gear grease on mating faces, and select diff oil that suits your driving style. Regular inspections after initial runs will confirm correct seating and longevity. Write Product Review Please sign in your account before you can write any review. Sign In Close
