OTC's Belt Tension Gauge is designed to allow you to properly check belt tension on drive belts. Correct tension ensures maximum belt and bearing life. Easy to read dual scale reads 30-180 lbs. (2.5-15 ft. lbs.) and 130-800 Newtons. High-grade materials ensure quality performance over the lifetime of the tool. BELT DRIVE PREVENTIVE MAINTENANCE AND SAFETY MANUAL tensile strength or certified/test tensile strength requirements, be advised that because Check belt tension and adjust as needed . 11. Recheck sheave or sprocket alignment . 12. 6 Drive tension procedure - the tension procedure is attached - see appendix V Tensioning methods for V-belts. For manual calcu-lation of accurate tensions for each drive, please see appendix VI Calculating belt tension. This covers the standard procedure for each type of the various tension tools now available, to suit all V-belt types. For a V-belt drive using four individual 3V belts enter "1" for the belt width ("Width" key) . The Sonic Tension Meter will display the static belt tension per individual belt . When measuring the belt tension in the V-belt drive, make sure the V-belts do not interfere with each other while vibrating . Safety ?rst - read and understand this manual before operating the SKF Belt Frequency Meter. Never use your SKF Belt Frequency Meter on moving belts. Switch off and isolate any belt drive system prior to taking tension measurements or attempting any other installation work. Do not drop the meter or subject either the meter or (see diagram below). The BROWNING ® belt tension checker, shown at left, is ideal for this procedure. 5. Check the tension at least twice during the first day of operation, and periodically thereafter. Be sure — use the inexpensive BROWNING® Belt Tension Checker See Form 5453 for more detail. How to increase Belt Life Keep sheaves and belts Do not use belt dressing: this deteriorates the belt, causing early failure. Tensioning Procedure: 1. Measure belt span. (See D
