8 GROB INC. Installation and Maintenance for Vari-Drive Motor Pulley #186 Installation Caution: Make sure Line Switch is on OFF. 1 Check motor shaft and key. 2 Before placing key on shaft, make sure pulley slides freely. Use a fine grade of emery cloth to remove any burrs or rust. Oil motor shaft for easy future removal of pulley. DO NOT FORCE PULLEY ON SHAFT. 3 Mount Pulley on motor shaft. Position its proper alignment to the driven pulley by using a straight edge bar or rule as shown below. Driven Pulley Straight edge bar or rule Note: Alignment must be accurate to avoid undue belt vibration or wear 4 When the alignment is correct, tighten the two self locking set screws. 5 REPLACING BELT: Turn speed crank to move motor towards gear box until it stops. 6 Use a wooden wedge to spread the sheaves apart far enough to permit belt to go on both pulleys. Remove wedge and rotate pulley until belt is tight. DO NOT PRY THE BELT ON. 7 The belt should run level between the faces of the sheaves. If one side rides high with belt on an angle, investigate immediately. Belt alignment may be the cause, or a defective belt. (over)

9 MAINTENANCE 1 The face of the disc and belt should be kept clean and free from grease or other liquids. 2 IMPORTANT: The pulley should be run through its speed range after each several hours of operation in order to lubricate all working surfaces. 3 LUBRICATION: The lubricant to be used should be a premium lithium based grease. Grease pulley after approximately 40 hours of operation. CAUTION: DO NOT OVER GREASE. One or two cubic inches of grease is sufficient. Too much grease could spread to belt.
