INSTALLATION INSTRUCTIONS

NOTE: Use the Model "T"

owner’s manual for trolley installation, where appropriate, with

the following exceptions:

TRACK ASSEMBLY

1. Assemble the track by installing the track spacers (Figure 1).

2. Determine which side of the door the operator will be mounted. Install the idler assembly at the header end of the track with the coupler sprocket toward where the operator will be installed.

3. Install a track spacer in the idler assembly, this keeps the track properly spaced.

4. Slide the slider assembly into the track with the take-up bolt towards the open end.

5. At the open end of track install the idler assembly that is normally the front idler on a trolley operator.

6. Install the chain, use the take-up bolt to adjust the chain tension to allow about 3" sag in the center (remove links if necessary).

7. Install the track and brace appropriately.

To prevent possible SERIOUS INJURY or DEATH, disconnect electric power to operator BEFORE installing.

ALL electrical connections MUST be made by a qualified

individual.

WARNING

Connect the Shaft From the Front Idler Assembly to the Extension Shaft by Coupling Two 48B12 Sprockets Together With #40 Chain and Masterlink.

INSTALL THE OPERATOR

1. Install the operator using the appropriate installation manual.

2. Remove the 50B12 output sprocket from the operator and install the new 50B35 sprocket on the operator. The 50B12 sprocket will be installed on the extension shaft.

INSTALL EXTENSION SHAFT

1. 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).

2. 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).

3. 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.

4. Install the 50B12 on the extension shaft, connect the chain between the operator and the shaft.

5. Complete the operator installation with the proper operator manual.

NOTES:

1. Smaller sprocket (50B12) is mounted on the extension shaft.

2. Larger sprocket (50B35) 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 reversing limits.
