(2) 235-3963 Clamp Assembly (Upper half) (2a) Bolt (2b) Hard washer (2c) Lock washer (2d) Nut
Once you have properly installed the tube assembly, tighten both bolts (4) to secure the bottom half of clamp assembly (2). Repeat for the other clamp assembly (4). Install the upper half of clamp assembly (2) by using two bolts (2a) and two hard washers (2b) through the upper clamp assembly, and two lock washers (2c) and two nuts (2d) on the lower clamp assembly. Repeat for the other clamp assembly. Refer to Illustration 8.
