4. Installation
4.1. RING GEARS
1. Jack up and block the frame. Make sure it sits level.
2. Remove
the wheels.
3. Deflate tires and break the bead so the tire will not melt during the welding
process.
4. Buff or grind off paint where ring gears will be welded in place.
5. With the wheel rim lying flat, insert ring gear into the inside of each rim. Use a
rubber mallet to ensure the ring gears are square to the inside of each rim
(Figure 4.4).
Important: To ensure ring gears are installed square, place a straight edge on each gear
and measure the distance to the tire rim in 2 places. Then, rotate the straight
edge 90° and measure again. If measurements are the same, then ring gear is
square inside the rim. Use a rubber mallet to level the ring gear if necessary.
6. Tighten the 4 set screws in rotation to lock the ring gear evenly into place on
each rim.
7. With ring gears now in correct position, weld 1” at each set screw (Figure
4.4).
4.2. WHEEL DRIVES
1. Remove the wheel hubs from the spindle (Figure 4.1).
2. Slide an axle cap assembly over each of the two spindles.
Note: Removing the hydraulic motor from the axle cap assembly will make the welding
process easier.
3. Measure 1-1/4” from each of the 4” x 4” spindle backing plates to the inside of
the axle caps (Figure 4.1).
Note: It may be necessary to grind down the gussets on the spindle slightly to obtain
the 1-1/4” measurement.
4. Put a level on the end of each axle cap and tack it in place. Ensure axle caps
are square with frame.
5. Install the rest of the over-center assemblies.
Warning: Before continuing, ensure you have read and understand the relevant information
