The Stark BX 42 is a cogged classical V-belt with a BX profile. When replacing a belt, the most reliable approach is to read the marking on the back of the old belt and match it exactly. This page covers what to check so you order the right belt the first time.
Start by locating the belt you need to replace. Clean the back of the belt and look for the profile and size marking. If it reads BX 42, this Stark belt matches that callout. The BX profile is a classical V-belt cross-section, and the cogged construction is visible as the notches on the underside. Confirm the profile letters and the size number before ordering.
If the old belt is worn, damaged, or the marking is unreadable, measure the outside length and compare it to the BX 42 listing. Do not rely on a belt that looks similar; a different profile or size can sit incorrectly in the pulley groove. The same size is also listed under Optibelt BX 42 and Dayco BX 42, so you may see those brand names on the shelf.
For a quote, send the part number BX 42, the quantity, and a photo of the old belt marking if you have one. Our team can confirm the BX profile and the 42 size, and help you verify it against your drive. If you are unsure, include the drive make and model or the pulley dimensions so we can cross-check.
