These locking clamps replace a standard quick release clamp already assembled to a windshield or used for assembling a windshield being installed for the first time.
1. Remove the windshield and place face down on a clean, soft surface with the mount brackets facing upward.
2. Remove the clamp and hardware from packaging. The locking clamp should be unlocked at time of installation. Note that the upper clamps can be identified by extensions that point upwards.
3. See Figure 1. Assemble the clamp assemblies and hardware stacks.
The cupped side of the Belleville (cone) washers must face each other and sandwich the windshield mount brackets at each mount point. Failure to orient washers correctly can reduce windshield's ability to break away in a collision, which could result in death or serious injury. (00422b)
4. One clamp at a time, with the clamp facing upward and inboard of the windshield bracket (2), tighten the shoulder bolts (1) enough to hold the clamp orientation to the windshield during mounting of the windshield to the motorcycle. The bolts will be fully tightened later.
5. Make sure all four clamps are in the open position, then bring the windshield (with the clamp side away from you) to the front of the motorcycle.
6. Continue with the installation using the instruction sheet.
