Hydraulic Maintenance
IMPORTANT
Lower the Drawbar Seeder to the ground, and relieve
hydraulic pressure before attempting to service any
hydraulic component.
WARNING
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of
cardboard, rather than hands to search for
suspected leaks. Wear protective gloves and
safety glasses or goggles when working with
Hydraulic System.
1. Check the tractor hydraulic fluid level per Tractor
owner's manual and after any leakage. Check fluid
level with the Hydraulic Cylinders in the extended
position.
2. If a Hydraulic Cylinder leaks, disassemble the parts to
determine the cause of the leak. Any time a Hydraulic
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. Do not attempt to perform any
service work under the implement without first
installing the Transport Locks. See Figure 3-6.
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 3-7.
Front and Rear Roller
Adjustment
NOTE
Failure to position the Clamp Band Socket Head Bolt
(Clamp Band open section) over the Roller Drum weld
seam will cause Clamp Band to loosen and slide.
After an initial run of 5-10 hours, check the Front and
Rear Roller Assemblies to ensure that the Wheels are
tight to one another and that the Clamp Bands are tight. If
not, slide the Roller Wheels tight together and adjust the
9K998-2306
TABLE OF CONTENTS
Roller Clamp Bands per Roller Adjustment Procedure.
Tighten the Clamp Band Socket Head Bolt (Clamp Band
open section) over Roller Drum weld seam to 75 Ft-Lbs.
Thereafter check Front and Rear Roller Assemblies
every 50-100 hours.
Roller Adjustment Procedure
1. Adjust the Front Roller Wheels first. Loosen Clamp
Bands and slide the Roller Wheels snug against each
other, centering the entire assembly under the
Deflector.
2. Position the Clamp Band Socket Head Bolt (Clamp
Band open section) over the weld seam on the Roller
Drum. See Figure 5-3.
3. Slide the Clamp Band against the End Wheel on each
end of the Roller and tighten the Clamp Band Bolt to
75 Ft-Lbs.
4. Adjust the Rear Roller Wheels in the same manner as
you adjusted the Front Roller Wheels except, start at
the center of the Rear Roller and align the peaks of
the Rear Roller Wheels with the valleys of the Front
Roller Wheels as best as possible. This will provide
the best alignment of worn Roller Wheels and
maximize seed germination.
