The Optibelt PJ 660 RB is a Poly-V (multi-rib) belt with a PJ profile and a 660 mm length. Before you fit it, inspect the drive and the sheaves so the new belt runs on a sound system. The same size is also listed under Gates PJ 660.
Start with the sheaves. Check the grooves for wear, embedded debris, and burrs, since a ribbed belt seats directly in the groove profile. Confirm the sheaves are aligned and that each one turns freely without play. Any groove damage will shorten the life of the replacement belt.
Next, check the rest of the drive. Look at the tensioner and idler pulleys for smooth rotation and correct alignment. Clean the grooves before fitting the Optibelt PJ 660 RB, and route the belt so every rib sits fully in its groove. Keep the belt free of oil and grease.
To request a quote, send the part number Optibelt PJ 660 RB by WhatsApp or email. If you are unsure of the profile or length, send a photo of the marking on the back of the old belt and the team will confirm the right belt or suggest an equivalent.
