The belt tensioner has no automatic spring. Check the tension by twisting the belt with your thumb and forefinger, midway along the longest straight run between the two main sprockets.metal oil seals cross reference.
If the belt tension is correct, you should just be able to twist it through 90 degrees. If you can twist it more or less than this, the tension needs to be adjusted.
Slacken the single nut in the slot of the tensioning assembly. Slide the tensioner clockwise to increase the tension, the other way to reduce it.
Tighten the tensioner nut and check the tension again. Readjust if necessary.metal oil seals cross reference.
