Set the flat outer edge of the V belt on a flat surface.

How to use v-belt rule. Ring on the plunger is even with the top of the wood. You should always use a Belt Tension Tool and refer to the manufacturers specs for each belt. Place the plunger end of the tension gauge on the top of the belt.

General Rules of Tensioning 1. Enables all three alignment conditions to be monitored. Reduce the center distance if there is too much force.

Theres no rule. If the v-belt breaks the engine accessories will stop working immediately. Draw a mark on the flat surface with a pencil to designate the starting point of the measurement.

V Belt Tension Methods. Inch of deflection for a V-belt. For Use With 3L 4L 5L A B 3V and 5V V-Belts up to 100 in.

They can make a big difference in belt life. Generally a single V-profile in the center of the belt is sufficient For thin belts with low transverse rigidity and also for wide belts two guiding profiles should be used and positioned as near to the belt edges as possible. Now for reality you dont have one A good Rule of Thumb seek approximately.

05022018 Compare this force with the value given in the V-belt tensioning table. Holding the tension gauge vertical to the belt press down until the bottom of the O.

Both V-profiles and flat profiles can be used in these cases. Keep belts free from foreign material which may cause slip. For example for a 100 span the deflection would be 10064 or approximately 1.

If the force is below the recommended value increase the drive center distance to provide greater belt tension. After the pulleys have been aligned it is very important to tension the belts to manufacturers recommendations. It will give the belts 50 to 100 longer life.

Includes Aluminum Slide Adjustment Wall Mounting Holes. Tension carefully using the instructions furnished. Never use a lever to install the belt it may lead to breakage of tensile cords of the belt.

Belts are NOT measured by diameter nor folding the belt in half. Roll the V belt along the flat surface until the paint mark rolls back to the flat surface. Use of a lever invariably develops permanent twisting of belts leading.

The correct tension on a V-Belt. 01092000 When designing V-belt or synchronous belt drives for demanding applications be sure to use service factors. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions.

Over tensioning shortens belt and bearing life. Never use belt dressing to correct slipping belts. Rolling or prying a belt on a drive gives one of two results both lead to shortened belt life.

After seating the belts in the groove and adjusting center distance so as to take up slack in the belts further increase the tension until only a slight bow on the slack. Slippage of used belts Always use a set with all new belts and same brand. An additional option is to wrap a small diameter stringrope around the belt then measure the length of the string.

Always consult an owners guide for the proper tension range. Check tension frequently during the first 24-48 hours of run-in operation. Incorrect belt tension as well as pulley misalignment adversely affects belt drive reliability and efficiency.

Multi-Rib Series V-belt tensioning adjustment can be made using a tension gauge or other type spring scale using the following pro-cedure. Rotate the V belt to place the paint mark against the flat surface.
