The Dayco BP78 is a classical wrapped V-belt with a B profile and a length of 2057.4 mm. Before you fit it, inspect the drive and sheaves so the new belt runs correctly and lasts.
Check sheave grooves for wear, rust, or embedded debris. Worn grooves let the belt sit too deep, reducing grip and causing slip. Confirm the sheave groove angle matches the 40-degree belt angle and that the B profile (17 mm top width, 11 mm height) seats properly.
Align the sheaves and check the shafts for runout. Misalignment or a bent shaft will wear the belt edges and shorten its life. With the correct length of 2057.4 mm, you can set the center distance and take up tension without forcing the belt over the sheaves.
If the drive uses multiple belts, replace all of them as a set from the same production run. This keeps lengths consistent and avoids uneven load sharing. Send the part number BP78 by WhatsApp or email to request a quote.
