1. Check to make sure that the brake plate seal is in
good condition, then stretch onto the brake plate
bushing (Fig. 206).
3. Loosely secure the brake plate, complete with brake
pad, to the brake lever and brake hub as shown in
Figure 207. Note that the bolt should go through
the brake plate rst. Secure with a nylon locknut
but do not tighten at this time. This will allow proper
alignment of the idler pulley later.
2. Hook the control link into the slot on the brake lever.
Place the spring and bushing onto the brake rod,
then slip the bushing and brake rod through the
hole provided in the brake lever. Finally, install the
bushing hub and anged head self-tapping screw
with the washer through the brake lever.

4. Install an idler hub into each side of the idler pulley
bearing, then slip the belt onto the idler pulley. Slip
the entire assembly between the brake plate and
brake lever. Secure the carriage bolt and nylon
locknut as shown in Figure 207.
5. Tighten the idler pulley bolt. Make sure that the idler
pulley spins freely.
