Inferno-Compatible 0.8M Steel Pinion 19T - Kyosho PNGS0819  [KY-PNGS0819]

Heavy-duty 0.8M pinion for Inferno chassis

This steel pinion serves as an RC-scale replacement designed for Kyosho Inferno models that accept 0.8M pinions. The item is listed as Kyosho PNGS0819, specified with 19 teeth and a 0.8M pitch, intended as a direct spare for compatible Inferno configurations.

Source compatibility notes reference Inferno MP10e and MP10Te and reference the MP11e in the same product family; the part is shown in context with IF403B and IFW639-58/59/60 spur options where a 0.8M pinion is standard. Always double-check motor shaft bore and set screw alignment before committing to fitment.

In tuning terms the 19-tooth count impacts the final driven ratio, delivering a compromise between low-end response and top-end velocity on electric RC circuits. When swapping pinions verify gear mesh with the spur, torque the hex/set screw correctly, and inspect adjacent ball bearings for any wear signs.
