The Optibelt Alpha Torque XL K 120 is a timing belt with an XL profile and a length of 304.8 mm. This page gives maintenance, engineering and purchasing teams the exact identification data for the belt.

For a timing belt, the profile and the length are the two figures that decide whether the belt will sit correctly on the pulleys and keep the drive timed. The XL profile defines the tooth form and pitch family, and 304.8 mm is the datum length. Both values are stated directly in the belt marking, so they are what you compare against the old belt or the drive specification.

When you request a quote, send the part number XL K 120 and confirm the profile and length you need. If the belt on the drive carries the same profile and length, the Optibelt Alpha Torque XL K 120 is the reference to quote. We carry Optibelt belts and can help confirm the right belt or suggest an equivalent.

Inspect the drive before ordering: check pulley teeth for wear, look for oil or debris in the teeth, and verify that the belt path is aligned. Replacing a timing belt is the moment to confirm the profile and length again, since a belt that is close but not exact will not run correctly.
