Drive Link Stretch Check

1. Make sure that the driven sprocket support (609) and both sprockets (516, 506) are fully seated.
2. Pull the drive link (507) toward the case at the indicated location.
3. Measure the distance between the case and the drive link:
^ If the measurement is 3.2 mm (1/8 inch) or greater, reuse the drive link.
^ If the measurement is less than 3.2 mm (1/8 inch), replace the drive link.
