• EXPANDING DIAMETER- The gas engine pulley crank shaft sleeve adapter adapts the larger wheel hole to the smaller axle and works together with the gas engine crankshaft to expand the crankshaft diameter for installing pulleys, gearboxes, etc.
• STEEL MATERIAL- The gas engine pulley adapter is made of high-quality cold-rolled steel, with CNC machining and rolling, making it very sturdy.
• SIZE- The crank shaft sleeve adapter has a sleeve inside diameter: 5/8", sleeve outside diameter 3/4", sleeve length: about 3", sleeve keyway slot: 3/16".
• APPLICABLE- Use shafts of different diameters to change the motor, and use different speeds or belts to change the pulley. Reduced the necessity of purchasing new motors or pulleys to maintain existing components and speed/power requirements.
• EASY TO INSTALL- The installation process of the shaft adapter is relatively simple and does not require complex operating skills. Its reasonable design and compact structure make the installation process more efficient and fast.
