Replacing a Mitsuboshi SPA 3150 narrow wedge V-belt starts with matching the marking on the old belt. This belt uses the SPA profile with a 12.7 mm top width, 10 mm height and 40° angle. The same size is also listed under Stark SPA 3150 and Optibelt SPA 3150.
When you pull the worn belt, read the back: it should show SPA 3150. The SPA profile is a narrow wedge section, and the 3150 marking identifies the length. Confirm the top width is 12.7 mm and the height is 10 mm. If the old belt is unreadable, measure the cross-section and compare it to these dimensions.
The 40° angle is part of the SPA profile and must match the pulley groove. A belt with the wrong angle or width will not sit correctly in the sheave. Check the pulleys for wear or debris before installing the replacement. If the drive uses multiple belts, replace them as a set so the load is shared evenly.
