Lift-Master 65 5209 User Manual

APPLICATION

Manual Hoist Modification for use with model T or GT operators.

• 655209 for 1/3 & 1/2 HP trolley operators with #48 drive chain

• 6552091 for 3/4 & 1 HP trolley operators with #48 drive chain

• 6552092 for GT operators with #41 drive chain

Modification provides hand chain operation for manually
opening/closing the door as follows:

1. A chain wheel is coupled to a cross header shaft which in turn
is coupled to the front idler of the trolley.

2. The front idler pulley is replaced by a #48 sprocket thus
allowing the chain wheel to drive the door arm.

Manual Hoist Modification

Used For Trolley Operators

655209 (1/3 & 1/2 HP trolley operators)

6552091 (3/4 & 1 HP trolley operators)

6552092 (GT operators)

PREPARATION

1. Door size to be indicated at time of order. If the door size
specified is 16 feet or taller a sash chain and key ring package
will also be included with packing list.

2. A cross header shaft is required for installation of this manual
hoist (not provided).

This shaft is available and will be provided if specified at time
of order.
1" cold rolled steel shaft 12 ft. long, for doors up to 20 ft. wide.

1" cold rolled steel shaft 20 ft. long, for doors over 20 ft. wide.

* Used on #41 Drive Chain only.
** Used on #48 Drive Chain only.

PACKING LIST

3. Hand chain length is twice the door height less 3 feet. Ensure
the proper length of chain has been provided.

4. If the manual hoist is being added to pre-installed operator, it
will be necessary to move the operator and track assembly
back (into the garage) approximately 6" to allow for installation
of the new front drive assembly.

1. Disconnect power to operator.

2. Existing Installation: Using proper temporary support for the

operator and track assembly, disassemble the existing front
bracket and idler assembly from the track end (Refer to
owner’s manual if necessary).

New Installation: Assemble the trolley operator according to
the owner’s manual. Use the new front bracket and idler
provided.

3. The chain hoist can be installed on the left or right side of the
door. Determine which side the chain hoist will be mounted on
and install the front idler assembly with the sprocket coupling
facing in the desired direction. Be sure to install a track spacer
at the end of the track.

4. Using the chain and master link provided, lengthen the existing
chain provided with the operator. Add/Remove links as required
for proper tension of the drive chain. Refer to the owner’s
manual for the proper tension value.

5. Position and mount the operator/track assembly as indicated in
the owner's manual.

NOTE: The front bracket will not pivot as shown in the manual so
temporary support of the operator will be required.

6. If you supply your own shaft you will need a length of 1" solid
shaft (ideally cold rolled steel). The approximate length of this
shaft should be one-half the door width plus 2 feet. Determine
the chain hoist location and cut the shaft to the desired length.

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

ALL installations and electrical connections MUST be made by
a qualified individual.

WARNING

WARNING

7. Install the 48B14 sprocket on one end of the shaft, (Figure 2).
Align sprocket flush with end of shaft, drill a 1/4" diameter hole
through sprocket hub and shaft. Secure using 1/4" x 1-3/4"
rollpin. Slide the two shaft support bearings onto the shaft.
Drill and pin the 40 tooth drive sprocket in desired location on
the opposite end of the shaft.

8. Supporting the far end of the shaft, butt together the two
48B14 sprockets and connect using the #41 chain provided.

9. Position the bearings on shaft so that one bearing is at the mid
point and the other as close to the 40 tooth sprocket as
possible. With the shaft level and using suitable hardware,
secure the bearings.

10.Vertically align the hand chain sprocket with the 40 tooth drive

sprocket. With the chain in place, and using suitable hardware,
secure the hoist housing. Align and secure the hand chain
retaining bracket.
