The Optibelt SPA 1957 RP is a narrow wedge V-belt from the Red Power 3 S=C Plus series. If you are replacing a worn belt, the first step is to confirm the profile and the length against the belt you are removing. This page gives you the exact figures so you can match it correctly.
The belt is an SPA profile with a 1957 mm length. Its top width is 12.7 mm, its height is 10 mm, and its angle is 40 degrees. These are the values to compare with the marking on the back of the old belt and with your drive documentation. A belt that is too long, too short, or of the wrong profile will not sit correctly in the pulley grooves.
When you check the old belt, read the profile and length directly from its back. If the marking is worn or missing, measure the outside length and the top width, then compare them with the figures above. The SPA profile is a narrow wedge section, so it should not be confused with a classical V-belt of similar width. If you are unsure, send a photo of the old belt and the drive setup.
