For Use With Models J, H and GH
659213-XX AND 6592131-XX
APPLICATION
This modification is available for model J, H and GH operators.
For 1/2 HP and lower side mount operators use #48 drive chain.
For 3/4 HP and higher side mount operators use #41 drive chain.
FUNCTIONS
Provides trolley type operation on wide standard lift doors where
a side mount operator is preferred over a draw bar operator.
NOTE: Use the Model "T" owner’s manual for trolley installation,
where appropriate, with the following exceptions:
TRACK ASSEMBLY
1. Assemble both tracks by installing the track spacers (Figure 2).
2. Install the idler assemblies onto the wall end of the tracks. One
idler assembly is set up with a coupling sprocket on each end,
and the other idler is set up with only one coupling sprocket.
3. Slide the slider assembly into both tracks from the open end.
Be sure that the take-up bolt is facing the open end of the track.
4. Install the idler roller assemblies onto the open end of the
tracks.
5. 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).
6. Determine which side of the door the operator will be mounted
on and install the track with the double idler on that side at the
center of the opening.
7. Install the track assembly with the single idler on the other side
of the center of the opening. Brace the tracks appropriately.
CONNECT TRACKS
1. Determine the length of the shaft needed to couple the two
tracks together and cut the shaft provided to that length. Slide
two bearing assemblies on the end of the shaft.
2. Install a 48B14 sprocket on each end of the shaft using the
(2) 1/4" x 1-1/2" roll pin provided (Figure 1).
3. Use a tape measure to set the slider assemblies the same
distance from the wall.
4. Couple the shaft between the two idler assemblies by butting
the 14 tooth sprockets together and connect with a #40 chain
and master link (Figure 2).
NOTES: 1. Shipped with 1/2 HP and lower side mount operators.
2. Shipped with 3/4 HP and higher side mount
operators.
