Automatic Band Brake Assembly and Installation
If assembling from new, or if the air motor and upright have been removed for service, the easiest way to assemble the automatic band
brake is to install everything except the cylinder assembly onto the upright and then mount the upright to the winch drum. The cylinder
assembly can be installed after the air motor is in place. The assembly and installation of the band brake follows these same basic steps.
Cylinder Assembly
1.
Lubricate and install the two small ‘O’ rings (110 and 109)
onto the cylinder rod (108), and insert the cylinder rod into the
piston (123).
2.
Install the retainer ring (111) that holds the cylinder rod on the
piston, and position the large ‘O’ ring (122) in the groove
around the piston.
3.
Thoroughly coat the cylinder rod, the ‘O’ rings, and the inside
of the cylinder with Lubriplate Mo-Lith No. 2 (or equivalent)
grease.
WARNING
Use care when removing or
installing the end cover on the
cylinder. Use a sturdy press with
at least 13 cm (5 inches) of travel, or use the threaded rod
method. Failure to exercise caution can cause mechani-
cal damage and/or injury.

4.
Insert the piston and cylinder rod assembly into the cylinder,
and drop the washer (128) into the open end of the piston.

5.
Set the cylinder (with the large open end upwards) in a sturdy
press. Place the two springs (124 and 127) on top of the washer
in the piston, set the large retainer ring (126) over the end
cover, and position the end cover over the springs. Carefully
press the cover into position on the cylinder.
NOTICE
The threaded rod method can be
used in the absence of a press.
Refer to cylinder disassembly
instructions.
6.
Press the end cover (125) down until the retainer ring groove is
exposed, and install the retainer ring (126).
Make sure the retainer ring is fully
seated into its groove.
7.
Remove the cylinder from the press. The cylinder assembly is
complete.
