This Optibelt RB belt is a Poly-V (multi-rib) belt in the PK profile with a length of 1690 mm. The profile and the length are the two values that matter most when you are selecting a serpentine belt for a drive.
The PK profile identifies the rib pitch and the number of ribs, so the belt seats correctly in the pulley grooves. The 1690 mm length is the effective length around the drive path. Match both values to the belt you are replacing; a belt with the same profile but a different length will not tension correctly, and a different profile will not fit the grooves.
The same size is also listed under Gates PK 1690, so you can compare the marking on your old belt with either listing. If the marking on the back of the belt is worn or unreadable, measure the length and count the ribs, then send those numbers with your equipment details.
We carry the Optibelt RB PK 1690 and quote by part number. Send the part number by WhatsApp or email and the team will confirm the right belt for your drive.
