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 in...

INSTALLATION 1. CLUTCH INSTALLATION Great care must be exercised to ensure proper offset & angular alignment between shafts to prevent premature friction disc failure. A. SHAFT PREPARATION & MOUNTING Mach III Clutch products are bored to fit a precision plug gauge for the specified bore size and should slide fit the mating shaft. Make certain that the shaft is free of burrs or nicks. It may be necessary to file or sand the shaft to ensure a slide fit. Never hammer the clutch onto the shaft. Hammering on the clutch may cause evident damage or subtle injury that will shorten the wear life of the...

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 pressure should not exceed 80 PSI. B. CONTAMINATION The friction material (pads) contained within this product will absorb oil, water, chemicals, and other contaminants. Depending on the type of contamination, clutch may either seize...

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. FRICTION DISC & SPRING REPLACEMENT (1) Remove clutch from shaft and place in vertical position with drive disc end facing upward. (2) Remove retainer ring, drive discs, springs and friction discs. (3) Drive discs should be clean, dry and free of burrs or nicks. (4) Reassemble drive & friction disc section according to reference drawing...

C. 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 more...
