Instructions and Specifications INTRODUCTION This manual provides instructions 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 adaptation. 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 System 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. CAUTION: 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.

! 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). 3 A
REMOVAL OF EXISTING COMPONENTS Park combine in 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 a 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. For convenience, remove the shaker shield and straw spreader. Disconnect steering tie-rod assembly from wheel ends. Retain all slotted nuts and cotter pins for later use. 2144, 2166 GRAIN & RICE & 2188 COMBINES WITH 92-120" AXLE CENTER SECTIONS ONLY Disconnect hydraulic hoses from steering cylinder and place aside for later connection. Plug hoses and cap cylinder ports. NOTE: Before disconnecting hoses, mark hoses and connectors to aid in correct connection later. If hose connections are switched, rear drive wheel will steer opposite steering wheel. ALL COMBINES Disconnect steering cylinder from wheel end and axle steering bracket. Retain slotted nuts & cotter pins for later use. If combine is equipped with sta-bars, remove sta-bar brackets located on axle center section. Remove all stub axle mounting bolts. Remove stub axles. Retain all mounting bolts for later use. Wheels and tires MAY be removed separately or left attached to stub axles. 2166 RICE & 2188 COMBINES USING MUD HOG AXLE CENTER SECTION Remove collar retaining the existing axle center section to the pivot support. Remove existing axle center section and thrust washers. Reinstall one thrust washer onto pivot tube of Mud Hog center section and slide tube and center section assembly into pivot support. Use one additional thrust washer at end of pivot tube. Reinstall retaining collar and check the endplay of the center section. Follow instructions on following page for adjusting endplay. 4
ADJUSTING AXLE CENTER SECTION ENDPLAY NOTE: On those combines which require installation of Mud Hog sta-bars, the axle center section MUST be free to move forward and backwards. Pull axle center section rearward tight against retaining collar. At the rear there MUST be a 1/4" gap - MINIMUM- for 2144, 2166 & 2188 combine center sections. See Figure 1. 2144, 2166 & 2188 Figure 1 If there is NOT a 1/4" gap, remove thrust washers as required until a 1/4" gap - MINIMUM - is obtained. See Figure 2. 2144, 2166 & 2188 Figure 2 5
ADJUSTING STEERING AXLE PIVOT SUPPORT Because of the large tires in the MUD HOG kit, certain rear tread center/axle pivot support combinations may result in rear tire interference with sheet metal, straw spreaders and guards, or rear fenders. Follow these steps: 1. Measure the frame height from the ground (see diagram above) with machine level. 2. Determine rear tire size and find corresponding static loaded tire rolling radius from table A. Subtract measured frame height from tire rolling radius. Using the resulting difference, go to table B to determine proper pivot support position. Table A Static Loaded Rolling Rear Tire Size Radius 14.9 x 24 R1 22.5 16.9 x 24 R1 24.3 16.9 x 24 R20 24.8 16.9 x 26 R1 24.1 16.9 x 26 R20 25.8 18.4 x 26 R1 25.7 18.4 x 26 R20 26.2 Table B Frame Height Subtracted From Rolling Radius Pivot Support Position With CI Center Section With MH Center Section #4 0 1.75 or less #3 0 to 2.00 1.75 to 4.00 #2 2.00 to 4.25 4.00 to 6.25 #1 greater than 4.25 greater than 6.25 Example: If the rear tire size if 16.9 x 26 R1, use table A to determine rolling radius of 24.1". Subtracting determined frame height of 22" from the rolling radius gives a result of 2.1". Using this result, go to table B. The result 2.1" falls in the range of 2.00 to 4.25. This range corresponds with pivot support position #2. Adjust the pivot support to this position. *Some combinations of tread center and pivot support positions may cause tire interference at rear of combines during extreme axle oscillation and steering. Further adjustments may be necessary. Refer to CASE INTERNATIONAL "OPERATOR'S MANUAL" in the section titled "WHEELS, TIRES, AND STEERING" for further instructions on adjustment of the steering axle pivot support. 6
