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

Delrin/Titanium 12T motor gear

This 12T motor gear is a direct aftermarket replacement designed for the Kyosho Mini-Z Overland series, supplied by GPM under part number DMOL012T. It is offered as a Delrin or Titanium Delrin variant to suit hobby-scale electric drivetrains where low friction and predictable wear behaviour matter.

Use case: install when replacing a worn pinion or when experimenting with drivetrain feel during tuning sessions. The component acts at the interface between the motor pinion and the rest of the gearbox, influencing engagement smoothness and audible noise at scale.

Installation notes: remove the motor following your Mini-Z Overland service procedure, slide the original 12T gear off the motor shaft, and fit the GPM replacement in the same orientation. Check mesh and endplay with the spur gear before finalizing, and secure the motor assembly using the original fasteners. No special tools beyond common hobby hex drivers are required for basic swap-outs.

Tuning role: swapping material types can alter how the drivetrain behaves under load; Delrin variants typically reduce squeal and run-in noise, while the Titanium Delrin option is chosen where slightly different wear characteristics are preferred. Keep the gearbox clean and inspect the gear for nicks or burrs after track sessions to preserve longevity.
