Mini-Z Overland 12 Tooth Motor Gear Delrin/Titanium DMOL012T by GPM  [DMOL012T]

12 Tooth Delrin motor gear with titanium-enhanced variant

This 12T motor gear serves as an aftermarket replacement for Kyosho Mini-Z Overland models and is listed as DMOL012T. Available in standard Delrin or a titanium-enhanced Delrin option, it is aimed at minimising friction and delivering predictable wear in small electric geartrains.

Use case: install to replace a tired pinion or to try different drivetrain responses during setup. The gear engages the motor pinion with the gearbox and affects both mechanical feel and scaled running noise.

Installation notes: follow your Mini-Z Overland motor removal steps, remove the original 12T gear, then slide on DMOL012T in the same position. Check gear mesh and axial play against the spur before tightening the motor, and retain the original mounting screws. Standard hobby hex drivers cover the task.

Tuning role: choosing different materials changes how the drivetrain handles load; Delrin is typically quieter on start-up while the titanium-enhanced variant shows altered wear behaviour. Regularly clean the gearbox and check for tooth damage after track use to maintain performance.
