Mini-Z Overland 12T Delrin Pinion Upgrade DMOL012T by GPM  [DMOL012T]

Delrin 12T motor pinion with titanium option

This 12T motor gear is a straightforward aftermarket swap for Kyosho Mini-Z Overland vehicles, identified as DMOL012T. Choose between plain Delrin or a titanium-infused Delrin version to match desired friction and wear behaviour in small electric drivetrains.

Use case: replace a worn pinion or experiment with drivetrain feel while tuning for traction and noise. The part interfaces the motor pinion with the gearbox and can change engagement smoothness and audible characteristics at scale.

Installation notes: remove the motor using your Mini-Z Overland disassembly steps, slide off the old 12T gear and install DMOL012T in the same alignment. Confirm mesh and axial play against the spur gear before securing the motor, and reuse the original screws. No specialised tools are needed beyond standard hex drivers.

Tuning role: material swaps alter how the gearbox behaves under load; Delrin tends to quiet run-in noise while titanium-infused Delrin provides a firmer wear profile. Inspect teeth after running and keep the gearbox free from grit to extend service life.
