Toro ProCore Processor Service Manual page 53

Removal (Fig. 19)
1. Have ProCore Processor attached to tow vehicle
and park both machines on a level surface. Secure lift
axle to frame with hitch pin and lynch pin to prevent lift
axle from shifting.
2. Engage vehicle parking brake, stop engine and re-
move key from the ignition switch. Make sure that Pro-
Core Processor engine is off. Chock wheels to prevent
movement of either machine.
3. Loosen straps that secure fuel tank to machine
frame (see Fuel Tank Removal in the Service and Re-
pairs section of Chapter 3 -- Engine). Shift tank position
toward right side of machine to allow access to lift cylin-
der pivot pins, fittings and hydraulic hoses.
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.
4. Relieve hydraulic system pressure.
5. Label hydraulic hose positions for assembly pur-
poses.
6. Disconnect hydraulic hoses from hydraulic fittings on
lift cylinder (Fig. 20). Locate and discard O--ring from be-
tween hoses and fittings. Allow hoses to drain into a suit-
able container.
7. Plug disconnected hoses and fittings to prevent con-
tamination.
8. Remove shoulder bolts (item 8) that are used to re-
tain lift cylinder pivot pins (item 6) to machine frame.
9. Support lift cylinder and slide pivot pins from the lift
cylinder and machine frame.
10.Remove lift cylinder from the machine.
11. If needed, remove fittings and O--rings from the lift
cylinder (Fig. 20). Discard O--rings.
12.Inspect bushing in axle and frame (item 13) for wear
or damage. Replace bushing if necessary. If bushing re-
placement is necessary, position bushing as follows:
A. Bushing in frame position should be installed so
bushing split is orientated toward front of frame.
B. Bushing in lift axle position should be installed so
bushing split is orientated toward lift axle.
ProCore Processor
Installation (Fig. 19)
1. If removed, install fittings with new O--rings into lift
cylinder ports (see Hydraulic Fitting Installation in the
General Information section of this chapter).
2. Position lift cylinder to the machine mounting points.
Make sure the lift 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 lift cylinder mounting holes with frame mounts.
Install pivot pins. Secure pivot pins to frame with shoul-
der bolts.
4. Remove plugs from disconnected hoses and fittings.
5. Connect hydraulic hoses with new O--rings to hy-
draulic fittings on lift cylinder. Tighten hose connections
(see Hydraulic Hose and Tube Installation in the Gener-
al Information section).
6. Return fuel tank to correct position and secure to
frame with straps and fasteners (see Fuel Tank Installa-
tion in the Service and Repairs section of Chapter 3 --
Engine).
7. Lubricate grease fittings on lift cylinder pivot pins.
8. Operate machine functions slowly until air is out of
Core Processor hydraulic system.
9. Check oil level in tow vehicle hydraulic reservoir and
add correct oil if necessary.
