Standard Pedestal Mount With Dropdown Plate - CPT AUTOPILOT CPT Installation Manual

Standard Pedestal Mount with Dropdown Plate

The dropdown plate lowers the motor box below the pedestal base
without the base obstructing the pedestal bracket.
Install Motor Box onto Pedestal Bracket and Dropdown Plate
1. Fasten the slotted motor box mounting bracket to the bottom of
the Dropdown Plate using any needed shims and the four
#10 screws.
If a shim is needed for aligning the belt with the wheel, the
thickness is based on the clearance distance between your spokes
and pedestal (measured 5ʺ out from the center of your wheel).
2. Fasten the Dropdown Plate to the Pedestal Bracket using four
#10 screws.
3. Fasten the motor box to the slotted mounting bracket using the
clamp lever, washers and knurled thumbnut. Lock the clamping
lever when the slotted bracket is in the middle of its adjustment
range—centered in the slots.
Hang assembly from belt and hose-clamp to pedestal
Place the drive pulley of the motor box in the belt allowing the box and bracket assembly to hang in the belt and rest snug
against the pedestal while you support it. Do not tighten the hose clamps yet.
Align belt with wheel and tighten hose-clamps
1. Attach the adhesive foam pads to the hose-clamps, not the pedestal. Pass the hose-clamps through the slots from the
inside of the bracket (start from the side with the two holes), around the pedestal and loosely tighten.
2.
Adjust the clearance from the pedestal:
·
If using the Deep Pedestal Bracket, the belt should align with the wheel when the edge of the stainless bracket is
2 ½ ʺ (6.4mm) from most pedestals using any required shims; see clearance chart below.
·
If using the Shallow Pedestal Bracket, the belt should align with the wheel when the edge of the stainless
bracket is 1ʺ (2.5mm) from most pedestals using any required shims; see clearance chart below.
3.
Temporarily tighten the hose-clamps enough to hold the assembly in position.
4.
Check for alignment: hold a yardstick or straight-edge against the back of the wheel adapter; it should be fairly
parallel with the belt when viewed from the side (clutch engaged; pushed in). Also look from above the wheel and
from the side to be sure the motor box is square with the wheel from all directions and not at an angle. If the belt is
not parallel you can squeeze the stainless bracket deeper or shallower on the pedestal as needed, or add or remove a
shim. If in doubt or your wheel is not uniform, favor the motor box being closer to the pedestal (rather than farther).
The slight belt slant will pull the clutch in which will help keep the clutch engaged.

Mounted to outer face
The dropdown plate may be mounted against
either the inner or outer face of the pedestal
bracket. It may be necessary to mount against the
inner face to get correct clearance when mounting
without a shim.
