ARC-60 REPAIR:
(Refer to FIG.5, Table 4)
Be sure to turn off PTO, lockout unit, allow time for fluid to cool, and
bleed hydraulic pressure, before removing any body panels or hoses
on or connected to ARC-60.
Drain hydraulic fluid from unit by removing the case drain plug (Item
17, FIG.3), once all the fluid has been drained replace and torque
according to Table 1. Do not re-use this fluid. Remove all connections
to the ARC60, these connections will be wet so be sure to have a
catch pan for the fluid that will be spilled. Cap and plug all hoses and
ports to prevent contamination. It is recommended to do any repair
work on a clean surface in a dust free environment.
Most repairs, such as fan, motor, relief and flow control valves, can be
accessed by simply removing the left side panel then removing and
replacing the part. To remove the left side panel (Item 7, FIG.5) you
must remove the front and top panels as well. If more in depth repairs
are necessary, simply remove the three manifold bolts and the two
radiator bolts that fasten the manifold and radiator to the base plate.
The entire internal assembly can then be lifted out of the frame.
Once the ARC-60 is out of its frame you will be able to remove and
replace any of the components. If the repair requires you to remove
the tank mount bracket (Item 24, FIG 4) mark the position of the
bolts on the tank mount bracket so you can reinstall in the same
position. This will ensure that your sight glass and tank caps will
fit concentrically within the case when you put the ARC-60 back
together. When you re-assemble the ARC-60 be sure use blue loc-tite
on all fasteners and torque according to Table 1.
