Tires
Recommended tire sizes are 480/45R17 and should be
inflated to 73 PSI.
When Re-Installing the 3/4-16 Flange Nuts tighten to 50
foot-pounds using the sequence in Figure 4-1. Then
tighten to full torque of 220 ft-lbs.

Wheel Hub Bearing
Maintenance
Wheel bearing maintenance should be performed at the
beginning of every season of use. Check the wheel
bearings periodically for excessive end play. If needed,
adjust or replace them using the following procedure:
1. Place the frame on blocks or stands sufficient to lift
the tire clear of the ground.
2. Remove the tire.
3. Remove the hub cap, cotter pin, slotted nut and
washer.
4. Remove the hub. Clean and inspect the bearings and
hub cavity. Replace any worn or defective parts.
5. Repack the bearings using a high-quality wheel
bearing grease.
6. Slide the triple-lip seal onto the spindle. Do not install
the seal into the hub.
NOTE
The triple-lip seals should point away from the hub to keep
contaminants out and allow grease to pass.
7. Slide the inner bearing cone and hub onto the spindle.
8. Install the outer bearing cone, washer and slotted nut.
9. Tighten the slotted nut while rotating the hub until
there is a slight resistance to wheel rotation. Then,
back the slotted nut off one notch, until the wheel
rotates freely without end play.
10. Slide the triple lip seal to the hub and install the seal
in the hub
11. Install a new cotter pin and re-install the hub cap.

Hydraulic Maintenance
IMPORTANT
Unfold, lower the unit to the ground, and relieve
hydraulic pressure before attempting to service any
hydraulic component.
1. Check the hydraulic fluid level per tractor owner's
manual and after any leakage. Check hydraulic fluid
level when the shanks are raised, wings are folded
and machine is raised for transport.
NOTE
Note when machine is lowered, wings unfolded and
shanks lowered for field operation the machine requires
approximately 1-1/2 more gallons of hydraulic fluid.
2. If a cylinder or valve leaks, disassemble the parts to
determine the cause of the leak. Any time a cylinder
is opened up, or whenever any seal replacement is
necessary, it is advisable to clean all parts and
replace all seals. Seal kits are available from your
Brillion dealer.
3. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
4. Transport locks are provided to hold the implement in
a raised position. See Figures 3-5 and 3-6. Do not
attempt to perform any service work under the
implement without first installing the transport locks.
Before servicing any hydraulic component, lower the
implement to the ground and relieve all system
pressure. If a hydraulic component is disconnected,
repaired, or replaced, it will be necessary to purge the
system of air before operation. See "Hydraulic Lift
System" on page 3-3 and "Hydraulic Fold
System" on page 3-3 on how to purge the hydraulic
systems.
Ensure that the hoses and fittings are properly assembled
at the Fold/Down Pressure Valve, See Figures 2-21 and
2-22.
