Belt Tension Gauge. Motion Pro. Style : Belt Tension. Designed to work with all belt drive models with a 10 lb specification. New L shaped pad fits all belt sizes. Compact design. Graduated scale for easy reference.
Nice tool. Fit and finish are good, easy to use, and helped me set my Night Train belt to the correct tension, which I had much looser than needed based simply on "feel".
The o-ring on the larger diameter that marks the graduations should be stiffer so that it remains horizontal. I replaced it. Other than that it works great and takes the guess work out of adjusting my belt.
This little tool takes ALL the guesswork out of setting the tension on your belt. Easily apply 10lbs of force to belt and measure how much deflection you have. No more going “by feel” for me. (Which wasn’t even close BTW) highly recommended!!
The product will do what it is meant to do but don't know how long you will be able to see indexing label because they are cheap stickers. Don't get oil on them it will get behind the stickers and they will end up moving
