Z2A / Z2R Drill Powered Pulley REPAIR PARTS

As the US, CA, AU, and NZ distributor of the Z2A and Z2-R, we offer full repair support for units purchased from HowNOT2. Most of the parts that wear on this device are easily replaceable by you and available to buy on this page.

Input Shaft

The input shaft is designed as a wear component and should be replaced every 20,000 meters of use to ensure minimal wear on the internal gears throughout the device’s service life.

Drill Adapter

The drill adapter houses a one way clutch which transmits motion in the counter-clockwise direction, but spins freely in the clockwise direction. This keeps the device from being damaged if the drill runs in the wrong direction. It is not common, but the clutch can wear down which would correspond with a loss of power transmitted through the device. This component can be replaced in about 5 minutes as shown in the video below. 

This product is a consumable. The manufacturer provides a one year limited warranty for defects in the materials and production process of the product.

The warranty does not cover damage to the product caused by wear, deformation, corrosion, oxidation, self-modification or repair, incorrect operation, improper storage and transportation, and other usage than for which it was designed. The input shaft components are wear parts and are not covered by the warranty.
