Kyosho PNGS0818 - Steel Pinion Gear 18T 0.8M for Inferno MP Series MP11e  [KY-PNGS0818]

Steel pinion for MP11e

This steel pinion is an RC-scale replacement part intended for electric touring chassis in the Inferno MP Series MP11e lineup. The item matches the 18-tooth count and 0.8M pitch indicated in the product code, and is manufactured in steel for wear resistance where a durable motor pinion is required.

Use this pinion when replacing a worn motor pinion or when changing tooth count to tune acceleration versus top speed; a single pinion swap alters final drive ratio and should be matched with the existing spur (large) gear and proper gear mesh. Before use confirm shaft fit and set mesh clearance to avoid premature wear on both pinion and spur.

Installation notes: remove the motor from the chassis to access the pinion, verify the motor shaft diameter and secure mounting, tighten set screws evenly, and rotate the gear to check for runout and binding. After installation perform a controlled bench run to verify smooth engagement before track use.

The PNGS0818 steel pinion serves as a durable replacement part for MP11e motor drives and as a straightforward tuning option for adjusting gear ratios on electric RC models.
