B. New Internal Assembly Installation
1. Orient both the finished assembly with respect to the housing and the main power shaft inside
the bottom of the housing in a horizontal line as shown in Figure 10.
ORIENT POWER SHAFT TANG
2. Orient the shaft clevis on the bottom of the motor to match that of the main power shaft.
3. While pressing the motor bracket arm against the lever switches, place the two #4-40 mount-
ing screws in the bottom bracket mounting holes, threads pointing down. Using a flat head
screw starter, install the screws.
4. Drop in the assembly directly over the main power shaft using the lower bracket guide posts
as centering guides. Lightly maneuver the switch assembly until the motor clevis is mated
with the main shaft tang. When this occurs, the assembly should sit flush on the bottom hous-
ing mounting holes and posts. The assembly should be stable in a flat position with respect to
the housing. A physical check can be performed to confirm proper shaft coupling. While hold-
ing the assembly secure about the housing, exercise the paddle shaft to observe the rotational
motion getting translated to the assembly. If the motor bracket does not rotate smoothly about
the switch bracket when the shaft is manually turned, then the coupling is incorrect. Remove
the assembly from the housing and reposition until it is properly coupled. Note: DO NOT
TIGHTEN THE LOWER MOUNTING SCREWS IF THE SHAFT IS NOT PROPERLY COU-
PLED. THE ASSEMBLY WILL BE DAMAGED AND WILL NOT OPERATE AS DESIGNED.
