ANTI-ROTATION ARM MOUNTING INSTRUCTIONS Mach III through-shaft mounted clutches and clutch-brake combinations require installation of an anti-rotation arm (also known as a reaction arm) which is discussed later...

INSTALLATION 1. INSTALLING A SPROCKET OR PULLEY Mach III units are typically shipped from the factory with the required sprocket or pulley preinstalled. This section pertains only to those who need to install or replace a pulley or sprocket in the field. Please use the links on page one of this document to obtain the detail sheet for your unit. This sheet will include the pilot diameter and other dimensions needed to machine the sprocket or pulley. Bore the sprocket or pulley for clearance (slide fit) over pilot and drill standard clearance holes for the number and type of screws on...

E. FINAL INSPECTION & TESTING Check alignment of the sprocket or pulley. Cycle the clutch with the machine off to check for air leaks and to ensure proper engagement and release. After a short run, check set screws and alignment. OPERATION A. AIR PRESSURE Torque output of this model is proportional to air pressure applied. Refer to the Product Detail Sheet for specifics regarding torque capacity. To achieve the longest possible bearing life, the air pressure supplied to the unit should be regulated to the minimum amount necessary to attain the required torque output. The maximum operating...

REPAIR KIT INSTALLATION PROCEDURE TOOLS REQUIRED Hex Wrench Set Rubber Mallet or similar soft face hammer Retainer (snap) Ring Pliers Scraper COMPOUNDS REQUIRED Grease O-ring Lubricant Loctite® #609 Retaining Compound Anti-Seize Lubricant (for re-installation) A. DISASSEMBLY (1) Remove clutch from shaft and place in vertical position with cylinder end facing upward. (2) Remove retainer ring from drive hub. (3) Remove air cylinder with bearing from drive hub. The air cylinder bearing is a slide fit on the drive hub and is affixed to the drive hub with a thin coating of Loctite®. You may need...

D. REASSEMBLY (1) Place the piston/bearing/cone sub-assembly over drive hub making sure the screw head in the cone is inserted in the corresponding hole milled in the drive disc. This prevents the cone from skidding on the drive disc. (2) Replace the inner retainer ring on the drive hub. (3) Inspect the inside diameter of the bearing in the air cylinder. If Loctite® residue is present, gently scrape and ensure that the surface is clean. (4) Apply a thin coat of Loctite® #609 retainer compound to the inside diameter of the bearing (applying excessive Loctite® will make future disassembly...
