This Optibelt Alpha Torque timing belt is identified by the part number L K 420. It has an L profile and a length of 1066.8 mm. Use these two dimensions to confirm it matches the belt you are replacing.
The profile defines the tooth shape and pitch that must engage the pulleys. The length determines whether the belt will fit the drive without altering the center distance. Both values are stated on the belt marking and in the part number, so a maintenance or purchasing professional can verify the replacement against the original.
When you request a quote, send the part number L K 420 and confirm the profile and length from the old belt. If the marking is worn, measure the length and check the tooth profile before ordering. MR Industrial Accessories supplies this Optibelt timing belt to customers in the United States, Canada, Mexico and South America.
