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...

DISASSEMBLY (1) Remove clutch from shaft and place in vertical position with cylinder end facing upward. (2) Apply air pressure to cylinder to relieve pressure from engagement springs. (3) Remove retainer ring from drive hub. (4) Remove air cylinder sub-assembly with bearing from drive hub. The air cylinder bearing is a slide fit...

Reassemble cylinder sub-assembly consisting of the piston, top plate and cone as shown in the diagram using a Loctite® adhesive at the bearing connection while making sure the pins of the piston are aligned with the holes in the cylinder and springs are properly seated in the pockets in the cylinder. In some models there are more spring pockets than springs. In this instance, make sure the springs are symmetrically located in the pockets in the cylinder. Replace inner retainer ring on drive hub. Apply a thin coat of Loctite® #609 retainer compound to the inside diameter of the bearing...
