and park machines on a level surface with the Processor
fully lowered. Engage vehicle parking brake, stop en-
gine and remove key from the ignition switch. Make sure
that ProCore Processor engine is off. Chock wheels to
prevent movement of either machine.
2. Secure lift axle to frame with hitch pin and lynch pin
to prevent lift axle from shifting.
3. Jack or hoist machine from ground and support with
jack stands (see Operator's Manual and Jacking In-
structions in Chapter 1 -- Safety).
4. Remove both wheel assemblies (see Wheel Remov-
al in this section).
5. Support lift axle to prevent it from shifting.
6. At lower clevis of lift cylinder, remove shoulder bolt
that secures pivot pin to lift cylinder. Slide pivot pin from
lift cylinder and lift axle bracket. Separate lift cylinder cle-
vis from axle bracket.
7. Remove lock nuts (item 12), flat washers (item 10)
and cap screws (item 15) that secure bearing tubes
(item 17) to machine frame.
8. Remove lock nuts (item 12), flat washers (item 10)
and cap screws (item 11) that secure axle blocks (item
9) to machine frame. Remove axle bearings.
9. Lower lift axle and remove from the machine.
10.Remove lynch pin and hitch pin that secures each
bearing tube to lift axle. Slide bearing tubes from lift axle.

Installation (Fig. 39)
NOTE: Bearing tubes should be installed on lift axle
with bracket flange toward end of lift axle tube.
1. Slide bearing tubes onto lift axle. Secure each bear-
ing tube to lift axle with hitch pin and lynch pin.
2. Position lift axle under machine.
3. Raise lift axle and align bearing tubes (item 17) to
machine frame. Install cap screws (item 15), flat wash-
ers (item 10) and lock nuts (item 12) to frame and bear-
ing tubes. Do not fully tighten fasteners at this time.
4. Align axle blocks (item 9) to lift axle and frame. Install
cap screws (item 11), flat washers (item 10) and lock
nuts (item 12) to frame and axle blocks. Do not fully tight-
en fasteners at this time.
5. Center lift axle in axle blocks and bearing tubes.
Tighten fasteners that secure bearing tubes (item 17)
first and then tighten fasteners that secure axle blocks
(item 9). Torque fasteners from 67 to 83 ft- -lb (91 to 112
N- -m).
IMPORTANT: When securing lift cylinder pivot pin
to frame, do not overtighten shoulder bolt. There
should be clearance between the shoulder bolt
head and pivot pin.
6. Install pivot pin to lower lift cylinder clevis and lift axle
bracket. Secure pivot pin to lift cylinder with shoulder
bolt.
Failure to maintain proper lug nut torque could
result in failure or loss of wheel and may result in
personal injury.
7. Install wheel assemblies (see Wheel Installation in
this section).
8. Carefully lower machine to ground. Make sure to
properly torque lug nuts from 70 to 90 ft- -lb (95 to 122
N- -m).
9. Lubricate grease fittings on lift axle pivot points.
10.Remove lynch pin and hitch pin from lift axle before
using ProCore Processor.
