Cylinder Disassembly
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.
1. Place the cylinder assembly in a press, and press down on the
end cover (125). Using a screwdriver, locate the chamfer on
one end of the retainer ring (126), and remove the retainer ring.
Slowly release the press allowing the springs to push the cover
away from the cylinder.
NOTICE
Before pressing down on the end
cover, operate the press so that it
can retract approximately 13 cm
(5 inches) when the springs extend to their uncompressed
state.
(Dwg. MHP0924)
2. If a press is not readily available, there is an alternative method
of disassembling the cylinder assembly. Thread a piece of 3/8
NC threaded rod approximately 36 cm (14 inches) long, fully
into the tapped hole in the cylinder rod (inside the cylinder).
Make sure the threaded rod is fully engaged. Slip a flat washer
over the threaded rod, and then thread a nut all the way down
to the cover. Tighten the nut until the cover moves far enough
to uncover the retainer ring, and remove the ring. Use a 12 mm
(approximately 7/16 wrench) to prevent the cylinder rod from
turning, and remove the nut from the threaded rod. Spring
pressure will push the cover away from the cylinder, allowing
complete disassembly.
WARNING
Use care when removing or
installing the end cover on the
cylinder. Make sure that the
threaded rod is fully engaged in the cylinder rod. If the
threaded rod starts turning while removing the cover,
double nut it or otherwise hold it and prevent it from
threading out of the cylinder rod. Failure to exercise
caution can cause mechanical damage and/or injury.
(Dwg. MHP0981)
3. Remove the springs (124 and 127) from the cylinder, and take
out the piston (123) and cylinder rod (108).
4. Remove the washer (128) inside the piston, take off the
retainer ring that holds the cylinder rod to the piston, and
remove the cylinder rod. This completes the disassembly of the
band brake and cylinder assembly.
