About the product: SHS steel pinion gear has been anodized black to improve wear resistance. The pinion gear works well with i.a. SHS’s own gear sets as long as the shimming is in order. The contact between the motor and the bevel gear is suprisingly important for the gun’s function, power consumptions and especially its noice. That is why it is important to pay attention not just to the wearing of the gear, but the shape of its teeth and angle when shimming the gears. Shimming, what is it? Shimming refers to adjusting the angle of the motor gear and the gearbox gears. It is always good to shim the gears when you change the gears or the bearings, or you install them into a new gearbox shell. In order to adjust the angle of the gears you need shims. You’ll find illustrated instructions for shimming in Tradetech!
