The Optibelt MXL 728 ZR is a timing belt with an MXL profile and a length of 184.91 mm. When replacing a belt, the most reliable approach is to match the profile and length to the belt you are removing.
To confirm this is the correct belt, read the marking on the back of the old belt. Look for the profile (MXL) and the length (184.91 mm). If the marking is worn or unreadable, measure the belt: profile is determined by tooth shape and pitch, while length is the datum length in millimeters. The MXL 728 ZR is the specific combination of MXL profile and 184.91 mm length.
Because timing belts are often replaced as part of a drive refresh, check the condition of the pulleys and tensioners at the same time. If the old belt is damaged or has been running for a long time, replacing related components can prevent premature failure of the new belt. If you need help confirming the right belt, send the part number and any photos of the old belt to our team.
