Slot.It PI6512E Press-on 12T 6.5mm Ergal SW/AW Pinion Gear is designed for use with Slot.It crown sidewinder and anglewinder driven gears. The term "ergal" is a trade name for 7075 aluminum alloy. This pinion gear has 12 teeth (12T), a diameter of 6.5mm and is compatible with motors having a 2mm diameter shaft commonly used by 1/32 slot car racers. Slot.It 6.5mm pinion gears are generally designed for use with Slot.It sidewinder and anglewinder gears; however, there are always exceptions. For more information about compatible pinion / driven gear combinations and available gear ratios, please click the link below. Slot.It Gear Ratio Chart Caution: Slot.It pinion gears are designed to be "pressed" onto the motor shaft. They should only be installed / removed using a pinion puller or pinion press designed specifically for that purpose. Using other tools/methods will likely result in a damaged pinion, a damaged motor or both. Our favorite tool for this purpose is a combination puller / press made by Slot.It (see "Related Products" below). Individual pinion pullers and pinion presses are also available. Package contains one (1) pinion gear. Formerly part number SIPI6512e
