INSTALL THE OPERATOR
1. Install the operator using the installation manual.
2. Remove the 50B12 output sprocket from the operator and install the new
50B20 sprocket on the operator. The 50B12 sprocket will be installed on
the extension shaft.
INSTALL EXTENSION SHAFT
3. Determine the length of the extension shaft to be used and cut it to this
length. Install the 48B14 sprocket provided on the end of the shaft by
drilling a 1/4" hole through the sprocket and shaft and pinning with the
1/4" by 1-1/2" roll pin provided. Be sure that the shaft does not extend
past the end of the sprocket and that the teeth of the sprocket are at the
end of the shaft (Figure 2).
4. Couple the shaft to the front idler assembly by butting the two 14 tooth
sprockets together and coupling them with the #40 chain and master link
(Figure 1).
5. Install the new bearing assemblies on the extension shaft. One of the
bearings should be at the operator end of the shaft as close to the 50B12
sprocket as possible to prevent shaft flex. Install the second bearing at
the mid point of the shaft. Be sure to properly pad out the bearings so
that the shaft is parallel to the header.
6. Install the 50B12 on the extension shaft, connect the chain between the
operator and the shaft.
7. Complete the operator installation with the proper operator manual.

NOTES:
1. Smaller sprocket (50B12) is mounted on the extension shaft.
2. Larger sprocket (50B20) is mounted to the operator where the (50B12)
sprocket was removed.
3. Bearing assembly should be mounted as close to the (50B12) sprocket as
possible to prevent shaft flex.
4. Refer to owner's manual for instructions on reversing operator direction.
