Drive Chain: Service and Repair

REMOVE OR DISCONNECT
Valve body cover.

Inspect
1. Midway between the sprockets and at right angles to the drive link, push the slack strand (bottom strand) of the drive link until all slack is removed and mark with crayon on the bottom side of the drive link.
2. Push up in the same manner and put a second mark on the case, making sure that both marks are made from the point on the drive link.

Measure
- The distance between the two marks. If the distance exceeds 22.2 mm (7/8 in.), replace the drive link.
- Make sure the three machined surfaces as indicated are flush with the machined surface of the case, if not when drive link measurement will be inaccurate.
