Through the use of switch kits, main gears can be installed and left on multiple vehicles allowing the user to move the MDU3. Note: Certain CNH vehicle models require the installation of spacer rings between the main gear and the steering wheel column. See Appendix A for details. Figure 2-1 Completed Main Gear Installation 12 OnTrac2+ GPS Assisted Steering System

17 MDU3 Installation Overview Install The Main Gear around the Steering Column Note: The installation of the main gear on the steering wheel does NOT require removing the steering wheel from the vehicle. 1. Remove 2 hex screws from the Smaller section of the Main Gear as shown in Figure 2-2. Figure 2-2 Main Gear Hex Screws 2. Remove the smaller section by pulling downwards as shown in Figure 2-3. Note: Tolerances are tight; pull directly downwards on smaller section. Figure 2-3 Main Gear Exploded View Installation Manual 13

18 MDU3 Installation Overview 3. Install the larger section under steering wheel around steering column. Install with the gear side on the top, closest to the steering wheel as shown in Figure 2-4. Figure 2-4 Installed Main Gear Note: Weave the gear around the steering wheel spokes if necessary; certain steering columns may be too thick for the gear opening. 4. Reinstall the smaller section using care to push directly upwards on the sector, because it is a very tight fit. Note: To facilitate the fit between the two gear sections, you may apply a drop of oil or apply a thin film of grease to the two alignment pins before mating the gear sections. 5. Reinstall and secure the 2 hex screws. At this point the main gear is assembled around the steering column below the steering wheel as shown in Figure 2-4. The gear is free to move around and must be now clamped to the steering wheel. Note: If you are installing a universal anti-rotation bracket on a CNH vehicle, a CNH fit kit may be required to move the steering away from the instrument panel. Contact your OnTrac2+ dealer for details. Examine Steering Wheel and Column Examine the steering wheel underside to determine if a spacer is necessary. A steering wheel with a soft covering material usually requires installation of a spacer to avoid interference with the MDU3 housing. Install Spacer (If Needed) Install the spacer around the steering column between the steering wheel and the main gear as shown in Figure 2-5. Flex the plastic spacer as needed to clear the steering wheel spokes as shown in Figure 2-6. The large chamfer on the outside diameter of the spacer ring should be facing the main gear as shown in Figure OnTrac2+ GPS Assisted Steering System

19 MDU3 Installation Overview Note: Two spacers with different thicknesses are included in the kit. Select the thinnest spacer that provides sufficient clearance between steering wheel and MDU3. Figure 2-5 Wheel with Spacer Chamfer Alignment Spacer Figure 2-6 Spacer Flexing Install the Clamp Ring The gear is free to move around and must be now clamped to the steering wheel. This procedure will install and center the ring gear for typical 3 spoked, normal shaped steering wheels. Installation Manual 15

20 MDU3 Installation Overview 1. Place the clamp ring on top of the steering wheel and install a minimum of 6 hex screws. Install a screw on each side of every spoke keeping the screws as close to the spokes as possible. At this stage keep the screws fairly loose to allow for centering. See Figure 2-7. Note: Two lengths of screws are provided in the kit to support different thicknesses of steering wheel spokes. Select the shorter of the two screws that still provides full thread engagement. Figure 2-7 Clamp Ring 2. With the main gear clamped loosely, rotate and move the gear until 3 screws touch the spokes evenly. Figure 2-8 shows the main gear rotated counter-clockwise until three of the mounting screws touch the steering wheel spokes evenly. Figure 2-8 Main Gear Centered The red circles indicate which screws are touching the spokes. 3. Check the installation by rotating the steering wheel and watching for off-center movement of the main gear. Repeat the centering process as necessary. 4. Tighten the screws with an Allen key. Torque to 6 lbf-in (0.7 Nm). Tighten the screws in a cross-pattern (as opposed to tightening each screw in a clockwise or counter-clockwise order). 16 OnTrac2+ GPS Assisted Steering System

CNH Fit Kit Installation Procedure The installation steps are listed below: 1. Install the Mechanical Drive Unit. 2. Install the Column Bracket. 3. Install the Anti-rotation Pin. 4. Install the Shift Lever. Install the Mechanical Drive Unit 1. Install the MDU3 onto the steering column. See MDU3 Installation on page 11. Note: For the CNH fit kit, we recommend the MDU3 orientation shown in Figure 8-1. Figure 8-1 Recommended MDU3 Orientation 44 OnTrac2+ GPS Assisted Steering System

49 CNH Fit Kit Installation Procedure Note: Do not use the plastic spacer ring provided with the main OnTrac2+ GPS Assisted Steering System installation kit. Note: If there is interference between the steering wheel spokes and the main gear, proceed with step 2 before securing the main gear to the clamp ring. 2. Remove the peel-off paper from the inner surface of the shims and place one shim between each steering wheel spoke and the main gear. See Figure 8-2.

50 CNH Fit Kit Installation Procedure Install the Column Bracket 1. Install the column bracket onto the vehicle s steering column as shown in Figure 8-3 and Figure 8-4. The elements of the column bracket surround the steering column to prevent the Mechanical Drive Unit from rotating while the system operates. Note: You may have to push down the rubber boot on some specific steering columns to install the column bracket correctly. See Figure 8-4.

51 CNH Fit Kit Installation Procedure 2. Loosen the two fifth wheel slider bolts. You will need to adjust the height of this element later. Refer to Install the Anti-rotation Pin on page 47 for details. 3. Align the two column bracket s nuts with the muffler clamp holes to fasten the bracket s elements together. Note: If the U-bolt option is not appropriate for your vehicle, install the straight-bolt option provided with this kit. Refer to Install the Mechanical Drive Unit on page 44 for details. Install the Anti-rotation Pin The anti-rotation pin is part of the Mechanical Drive Unit (MDU3). It prevents the MDU3 from rotating around the steering column when the OnTrac2+ GPS Assisted Steering System operates. We strongly recommend the use of Loctite 242 (or equivalent) on the anti-rotation pin threads. Note: Loctite 242 not supplied by the manufacturer. 1. The anti-rotation pin can be set at three different locations on the MDU3. Choose the location for the anti-rotation pin that best fits your vehicle steering column configuration. See Figure Fix the Mechanical Drive Unit anti-rotation pin to the flange bearing hole as shown in Figure Adjust the height of the fifth wheel slider so it matches the height of the anti-rotation pin. 4. Align the anti-rotation pin to the flange bearing hole and adjust the fifth wheel slider. Installation Manual 47
