The Optibelt A 158 is a classical V-belt in the Red Power series, built to the A profile with a 4064 mm length. When you are replacing a worn belt, the marking on the back of the old one is the fastest way to confirm you have the right part. This page covers what to check before you order.

Start by reading the back of the belt you are removing. The A profile tells you the cross-section: 13 mm top width, 8 mm height and a 40 degree angle. The 158 designation corresponds to the 4064 mm length. If the old belt is worn or the marking has rubbed off, measure the outside length and compare it to 4064 mm, and check the cross-section against the 13 mm by 8 mm dimensions.

The same size is also listed under Stark as A 158, so if you are working from a different brand's number, that is the equivalent to look for. This is a classical V-belt, not a narrow wedge or cogged profile, so it is matched on the A profile and the 4064 mm length together, not on either one alone.

For a quote, send the part number A 158 and the brand Optibelt, along with the profile and length if you have them. If you are unsure whether this is the correct belt, send a photo of the marking on the old belt and the drive it runs on, and the team can confirm the match or suggest an equivalent.
