Kyosho PNGS0819 Steel Pinion Gear (19T/0.8M/?5.0)  [KY-PNGS0819]

Steel motor pinion for Inferno series

This steel pinion is an RC-scale replacement part intended for use on Kyosho Inferno models that accept a 0.8M pinion. The listing identifies the part as Kyosho PNGS0819 with 19 teeth and a 0.8M pitch, and it is presented as a direct spare for compatible Inferno setups.

Compatibility references in source material include Inferno MP10e and MP10Te models and MP11e in category context, and the part is shown alongside IF403B and IFW639-58/59/60 spur options where a 0.8M pinion is used. Confirm exact model fitment and shaft/bore dimensions before installation, since pinion fit depends on motor shaft diameter and set screw alignment.

For setup and tuning the 19T count plays a direct role in final drive ratio, offering a balance between acceleration and top-end speed on typical electric RC tracks. When changing pinion size check mesh clearance with the spur, verify hex screw torque, and inspect nearby ball bearings for wear to maintain drivetrain reliability.
