The Optibelt A 39 is a classical V-belt with an A profile and a length of 1041 mm. When you need a replacement, the marking on the back of the old belt is the fastest way to confirm you are ordering the same size. This belt is part of the VB / HVAC Power series and is identified by its top width of 13 mm, height of 8 mm, and 40-degree angle.
Start by reading the old belt. Look for the part number and profile on the back; a marking such as A 39 tells you the profile is A and the length is 1041 mm. If the printing is worn, measure the top width and height to confirm the profile. The A 39 has a top width of 13 mm and a height of 8 mm, with a 40-degree angle.
The same size is also listed under Stark as A 39. If your drive uses multiple belts, replace them as a set so the load stays even across all grooves. Inspect the sheaves for wear, alignment, and debris before installing the new belt, and check the tension after the first run-in period.
