4 Instructions and Specifications This manual provides instruction for installing the Mud Hog Drive System on hydrostatic machines. Various machine options such as rear axle width and front tire size affect Mud Hog adaption. These differences are specifically referred to in these instructions. Always follow the instructions which refer to the exact option configuration on the machine being converted. A complete pictorial breakdown of all the individual parts in the Mud Hog Drive Systems can be found in the Mud Hog Parts Catalog. Refer to this catalog for proper identification of parts required for service. General The terms right and left in these instructions are the same as the operators right and left hand when positioned in the operator s seat facing forward. IMPORTANT: Cleanliness is essential when installing or servicing hydraulic components. When making hydraulic connections, areas surrounding the connection should be steam cleaned or washed with solvent so that contamination will not enter the system. Always keep hoses and connectors and ports suitably capped or covered to keep contamination out of the system. CAUTIN: Make sure that system pressure is relieved before disconnecting any lines or connections. Pressurized fluid escaping from the system can cause serious personal injury. Torque Specifications Recommended for use with Mud Hog Fasteners Recheck all bolt & nut torque after 1 hour s use and again after first day of use. Periodically check tightness every 100 hours of use thereafter. Note: bolts that require Loctite should not be re-tightened once Loctite has had time to cure. Note; When using original equipment fasteners, adhere to manufacturers recommended specifications. Grade 8 (Class 10.9 metric) Bolts and Grade C Locknuts Size S.A.E.

5 Safety Procedures 1) READ THESE PROCEDURES COMPLETELY. Make sure you fully understand all controls BEFORE operating the system. 2) The safety information given does not replace safety codes, insurance needs, or federal, state, and local laws. 3) Standard safety procedures should be observed and practiced when operating or servicing the Mud Hog system. CAUTION should be practiced at all times. 4) All components MUST be securely and correctly mounted and connected BEFORE operating the system. 5) In the event of any malfunction in the system, the Mud Hog should be shut OFF immediately and not restarted until the machine is correctly serviced. 6) When raising the machine, make sure that a dependable left device is used to adequate capacity. Use suitable jack stands to support machine. Apply PARK or EMERGENCY BRAKE and block the front wheels to prevent the machine from rolling. 7) DANGER Escaping fluid under pressure can have sufficient force to penetrate the skin, causing serious personal injury. Fluid escaping from a small hole can be almost invisible. Use a piece of cardboard or wood rather than your hands, to search for suspected leaks. 8) DO NOT extend the axles beyond the distance stated in the instructions. 9) DO NOT alter axles in ANY manner alterations may reduce strength resulting in possible damage or personal injury. 10) DO NOT alter any component of the Mud Hog system. Unauthorized modification may result in possible damage or personal injury. 11) DANGER Failure to follow proper procedures when mounting a tire on a wheel or rim can produce an explosion which may result in serious bodily injury. DO NOT attempt to mount a tire unless you have the proper equipment and experience to perform the job safely. 12) WARNING Decals MUST be obeyed completely to prevent possible damage or injury. If decals are destroyed, lost damaged or cannot be read, replace immediately. 13) WARNING Any damaged hi-pressure hose should be replaced with a comparable 4-wire braid hose (DO NOT use a 2 or 3-wire braid hose). 4

6 Removal of Existing Components Park combine in a clean working area. Allow adequate room to remove rear axles. Apply"PARK" or" EMERGENCY BRAKE" and block front wheels to prevent combine from rolling. Using suitable lift device, jack or hoist, raise rear of combine so that rear tires are several inches off the ground. Place jack stands securely under combine rear frame. Do NOT support combine under axle center section. The axle center section MUST be free to move during the installation procedure. Disconnect and remove tie-rod ball joints from wheel ends. Remove all wheel end mounting bolts. Remove wheel ends. Wheels and tires MAY be removed separately or left attached to wheel ends. Retain all mounting bolts for later use. NOTE: Always refer to John Deere "TECHNICAL MANUAL" when disassembling any J.D. components. Tread Center Adjustments Available tread center settings are A: 122", B: 130", C: 138", D: 146" and E: 154". Tread settings can be adjusted by sliding stub axles inside of center section. The first figure shows the standard rear axle assembly. The second figure shows the axle in high clearance position. Note: 18.4 x 26 or larger tires may require wider tread settings for proper clearance and steering. See John Deere Manual for further information. 5

7 Mounting Adapter Plates and Wheel Drive Assemblies Permanent Loctite must be used on bolts. Bolts should be thoroughly cleaned before applying Loctite. Use supplied 3/4-16 x 2 1/2 bolts in place of original bolts. NOTE: grade 9 bolts must be used. Torque 3/4-16 bolts to ft.lbs. Do not re-torque bolts that have had Loctite applied once Loctite has had time to cure. NOTE: Mounting pins must be in place before assembling adapter plate to stub axle. Failure to do so will void warranty. Adapter plates are painted and coated with a rust preventative. Any paint, rust preventative or foreign material on mounting surface must be removed prior to assembly to ensure proper clamp load is achieved between wheel drives and JD stub axle mounting surfaces. Excess paint/rust must be removed from JD stub axle endplate. Check flatness of JD endplate prior to installation to ensure proper clamp load is achieved. If endplate is not flat, axle must be replaced prior to Mud Hog installation. John Deere Cast stub axle with 5 bolt pattern is required for this installation. 5 Bolt Stub Axle to Adapter Plate Attachment Service Part Information Torque ¾ x 2 1/4 Bolts to Foot Pounds. Permanent Loctite must be used on bolts. Bolts should be thoroughly cleaned before applying Loctite. Do not re-torque bolts that have had Loctite applied once Loctite has had time to cure.

34 4WD Mud Hog Vinyl Decal Application Instructions To apply your decal, please follow the instructions below: 1. Clean area above rear wheel on ladder side of machine to remove dirt and grime. 2. Without removing the paper backing, position decal on surface exactly where you want it. 3. Once the decal is in position, place a piece of masking tape along the top edge to hold the decal in place. 4. The decal should be sitting on the surface like a flap. Lift up the decal and remove the paper backing. 5. With the backing paper completely removed from the decal & transfer tape, gently lower the decal with the transfer tape back down to the surface and rub it down lightly with your hand. 6. The transfer tape should still be on the side of the decal facing you. This allows you to rub the decal without scratching or damaging the decal. Take a squeegee or credit card and firmly rub the transfer tape and thus the decal until it is firmly adhered to the surface. 7. Finally, peel off the transfer tape and masking tape gently. The decal will adhere to the surface much more aggressively than the transfer tape. The transfer tape should lift easily leaving behind no sticky residue. 8. Your decal installation is complete. If there are bubbles present under the decal that cannot be removed by working them to edge, a small needle or pin can be used to puncture the bubble and remove the air. A small pin hole will not be seen after the air bubble has been worked out.
