The Stark C 103 is a classical V-belt with a C profile, a 22 mm top width, a 14 mm height, and a 40° angle. To match it to the belt being replaced, read the marking on the old belt and confirm the profile and length before ordering. This page covers what to check so the replacement fits the drive correctly.

Start with the marking on the back of the belt you are replacing. If it reads C 103, this Stark belt matches that profile and length. Also measure the top width and height with a caliper: the C profile measures 22 mm across the top and 14 mm high, with a 40° angle. If the old belt is worn or the marking is gone, use those dimensions and the length from the drive documentation to identify the correct size.

The same size is also listed under Mitsuboshi C 103, Gates C 103, and Optibelt C 103, so you can compare those listings if you are cross-checking a belt from another shelf. When you request a quote, send the part number C 103, the profile C, and the measured top width and height. If you are unsure between two sizes, send a photo of the old belt marking and the drive sheave dimensions.

Inspect the drive before installing a replacement: check sheave grooves for wear, confirm alignment, and verify the belt sits correctly in the groove. If the drive uses multiple belts, replace them as a set so the load is shared evenly. After installation, check tension according to your maintenance practice and recheck after the first run-in period.
