This 12T motor gear is a purpose-designed aftermarket replacement for Kyosho Mini-Z Overland vehicles, identified as DMOL012T. Offered in Delrin or a titanium-infused Delrin variant, the design focuses on consistent tooth profile, low friction engagement and reproducible wear behaviour for small-scale motor geartrains.
Use case: replace worn pinions or test material effects during setup and tuning. The component interfaces the motor shaft to the gearbox and directly influences engagement smoothness, noise signature and load response.
Installation notes: remove the motor per the vehicle service instructions, remove the existing 12T gear and install DMOL012T maintaining original orientation. Verify gear mesh and axial clearance against the spur gear before final clamping, and reuse OEM fasteners where compatible. Typical hobby hex drivers are sufficient for installation.
Tuning role: material selection alters the mechanical damping and wear progression; Delrin typically reduces run-in noise while the titanium-infused option modifies wear rate under repeated load cycles. Maintain gearbox cleanliness and inspect gear teeth regularly for burrs or damage to preserve drivetrain reliability.
