Mini-Z Overland 12T Motor Pinion Delrin/Titanium DMOL012T by GPM  [DMOL012T]

12T Delrin and titanium-infused pinion for Mini-Z Overland

This 12T motor gear is a direct aftermarket replacement designed for the Kyosho Mini-Z Overland series, part number DMOL012T. It is available in standard Delrin or a titanium-infused Delrin option to suit small electric motor drivetrains where low friction and predictable wear matter.

Use case: fit this gear when replacing a worn 12T pinion or when testing different drivetrain characteristics during tuning. The pinion sits between the motor shaft and the gearbox, affecting engagement smoothness and the scaled noise profile.

Installation notes: follow your Mini-Z Overland service routine to remove the motor, slide the original 12T gear off the shaft, then install the DMOL012T in the same orientation. Verify gear mesh and endplay with the spur gear before final tightening, and reuse the motor fasteners. Only common hobby hex drivers are needed for this basic swap.

Tuning role: selecting Delrin or titanium-delrin changes run-in noise and wear patterns; Delrin often reduces squeal while the titanium-infused variant gives a different wear characteristic under load. Keep the gearbox clean and check the teeth for nicks or burrs after running to maintain longevity.
