Before a belt like this goes on, check the drive itself. Look at the sheave grooves for wear, buildup or damage, confirm the pulleys turn freely and are aligned, and check that the shafts and bearings have no play. A worn or misaligned sheave will shorten the life of any new timing belt, so correct anything you find before fitting.
The belt is identified by the code on its back: 50 AT10K13 / 11400 AFX. Read that marking rather than working from memory, because the profile, length and pitch all have to match the drive. If the old belt is worn or the marking is unreadable, measure the drive and send us what you have.
For a quote, send the full part number, the quantity you need, and the drive details or a photo of the old belt marking. If you are unsure whether this AT10 profile and 11400 mm length suit your application, our team can review the details and confirm the right belt or suggest an equivalent.
