Additional information

This interlock washer, part number 727970, installs between fastened components to help maintain proper spacing and support secure assembly. Correct placement helps prevent loosening and uneven wear during operation.

If components loosen over time, shift out of position, or show wear around the fastener area, a worn or missing washer may be the cause. Flattening, cracking, or deformation can reduce its ability to hold parts securely.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Position the washer correctly before tightening fasteners, and tighten hardware evenly so components remain aligned.
