Removal (Fig. 21)
1. Park ProCore Processor on a level surface. Secure
machine lift axle to frame with hitch pin and lynch pin to
prevent lift axle from shifting. Make sure that ProCore
Processor engine is off. Remove key from the ignition
switch. Chock wheels to prevent movement of machine.
CAUTION
Operate all hydraulic controls to relieve system
pressure and to avoid injury from pressurized
hydraulic oil. See Relieving Hydraulic System
Pressure in the General Information section of
this chapter.
2. Make sure that Core Processor hydraulic system
pressure has been relieved before proceeding with off-
set cylinder removal.
3. Label hydraulic hose positions for assembly pur-
poses.
4. Disconnect hydraulic hoses from hydraulic fittings on
offset cylinder. Locate and discard O--ring from between
hoses and fittings. Allow hoses to drain into a suitable
container.
5. Plug disconnected hoses and fittings to prevent con-
tamination.
6. Remove cap screws, flat washers and flange nuts
that are used to retain cylinder pins (item 2) to machine
frame.
7. Support offset cylinder and slide cylinder pins from
the offset cylinder and machine frame.
8. Remove offset cylinder from the machine.
9. If needed, remove fittings and O--rings from the off-
set cylinder. Discard O--rings.
ProCore Processor
Installation (Fig. 21)
1. If removed, install fittings with new O--rings into offset
cylinder ports (see Hydraulic Fitting Installation in the
General Information section of this chapter).
2. Position offset cylinder to the machine mounting
points. Make sure the offset cylinder fittings face the
front of the machine.
IMPORTANT: When securing pivot pins to frame, do
not overtighten shoulder bolts. There should be
clearance between the shoulder bolt head and pivot
pin.
3. Align offset cylinder mounting holes with frame
mounts. Install pivot pins. Secure pivot pins to frame
with shoulder bolts.
4. Remove plugs from disconnected hoses and fittings.
5. Connect hydraulic hoses with new O--rings to hy-
draulic fittings on offset cylinder. Tighten hose connec-
tions (see Hydraulic Hose and Tube Installation in the
General Information section).
6. Lubricate grease fittings on offset cylinder.
7. Operate machine functions slowly until air is out of
Core Processor hydraulic system.
8. Check oil level in tow vehicle hydraulic reservoir and
add correct oil if necessary.
