indoors. Remove all clamping cylinders
from the clamp ring and fill each cylinder
with Mobilarma 522 or equivalent. Drain
each cylinder and plug port with a metal
SAE O-ring plug. Coat all unpainted
surfaces with CRC Industries SP 400
(corrosion inhibitor) or equivalent. Place
cylinders in a crate with plug facing up and
store indoors. Remove the clamp ring and
coat any unpainted surfaces on the
adjustment ring and clamp ring with CRC
Industries SP 400 (corrosion inhibitor) or
equivalent. Reinstall clamp ring without
clamping cylinders. Cover the threads of the
adjustment ring and clamp ring with a
liberal amount of lithium based grease NLGI
No. 1 containing a minimum of 3%
molybdenum disulfide. Remove the
adjustment cap seal and place in a heat
sealed plastic bag along with an
appropriately sized bag of desiccant.
Desiccant can be purchased in various sizes
based on the volume of the packaged area,
the length of storage time and the conditions
in which the package is stored. Desiccant
bags are available from most packaging and
shipping companies.
4. Tramp Release Cylinder Assemblies —
Remove the nut and cone and coat parts with
CRC Industries SP 400 (corrosion inhibitor)
or equivalent. Check the precharge on the
accumulator to insure it is between 5 and
15 psi. Remove the mounting bracket from
the bottom of the cylinder and place the
cylinder on its side with the boss facing
upward. Remove the O-ring plug from the
port just above the accumulator and fill the
cylinder with Mobilarma 522 or equivalent.
Do not remove the plugs from the two side
ports. Filling the cylinder this way will
allow oil to enter the accumulator. When the
cylinder and accumulator are full install an
SAE O-ring plug in the port. Approximate
volume of oil required per cylinder and
accumulator is 15 liters (4 gallons). Coat the
unpainted surfaces on the outside of the
cylinder assembly with CRC Industries
SP 400 (corrosion inhibitor) or equivalent.
Replace the mounting bracket and place the
assembly in a crate on its side with the
accumulator facing up. Store the crate
indoors.
5. Eccentric Assembly — Remove the
counterweight and gear from the eccentric
assembly. Coat all surfaces with CRC
Industries SP 400 (corrosion inhibitor) or
equivalent. Because these parts are in the
normal flow path of the lubricating oil when
the Crusher is running, it is recommended
that these parts be stored indoors or are
covered by a tarpaulin if stored outdoors.
6. Head Assembly — Apply a coating of at
least 4 mils (0.10 mm [0.004 inches])
(2 coats) of CRC Industries SP 400
(corrosion inhibitor) or equivalent to the
head ball, the bore of the upper and lower
head bushings, machined surfaces of the
head above the head ball (if the Crusher uses
a clutch style antispin device some
additional disassembly may be required) and
all areas of the head adjacent to the T-seal.
7. Bowl and Hopper Assembly — Remove the
hopper and adjustment cap from the bowl to
expose the wedges and hardware used for
mounting the bowl liner. Coat all hardware
and unpainted surfaces with CRC Industries
SP 400 (corrosion inhibitor) or equivalent.
There is no need to coat the surfaces of the
bowl liner. Clean the threads of the bowl and
recoat with CRC Industries SP 400
(corrosion inhibitor) or equivalent. Cover
the threads of the bowl with a liberal amount
of lithium based grease NLGI No. 1
containing a minimum of 3% molybdenum
disulfide. Apply a coating of Mobilarma 522
or equivalent to the fasteners and remount
the adjustment cap to the bowl. The
assembly can now be stored outside exposed
to the elements. To reduce corrosion due to
exposure the bowl and hopper assembly can
be covered with a sheet of 8 mil. black
polyethylene to prevent water from seeping
into the Crusher. The covering must be
supported with bracing and positioned to
shed any water away from the component.
8. Hydraulic Power Unit — Remove the fill
plug from the top of the reservoir and drain
any existing oil from the tank. Remove the
top of the filter inside the cabinet. Start
filling the filter housing with Mobilarma
