The Stark B 42 is a classical V-belt with a B profile. Its cross-section measures 17 mm at the top, 11 mm in height, and a 40-degree angle. This page helps you confirm it matches the belt you are replacing.
Start by reading the marking on the back of the old belt. A B 42 marking points to this profile and size. If the old belt is worn or the marking is gone, measure the top width and height with a caliper and compare to 17 mm and 11 mm. The 40-degree angle is the standard V shape for this profile.
The same size is also listed under Optibelt B 42, so you can use that as a reference when checking your replacement. For a quote, send the part number B 42, the brand Stark, and the quantity you need. If you are unsure, send a photo of the old belt's marking and the drive it runs on.
Inspect the drive before installing a new belt. Check sheave grooves for wear and alignment, and confirm the belt sits correctly in the groove. If multiple belts run together, replace them as a set to keep tension even. The Stark B 42 is a classical V-belt, not a narrow wedge or cogged belt.
