Alignment Instructions for Roadmaster Tow Dolly RM-2000-1
Question:
Im not sure of the year of the tow dolly as I purchased it second hand however the tires are wearing to the inside. Is there any way to do an alignment to correct this problem?

Tire wear on the inside tread of both tires would not necessarily be caused by any alignment problems. It could also indicate that the dolly was likely overloaded which could mean that there are parts that are damaged and need to be replaced. Inspect the parts as you go through the instructions below.
There are alignment instructions though depending on the tow dolly you have. For # RM-2050-1 follow these instructions:
1. First make certain the steering pin (Figure 1) is in place.
2. With the coupler 18 inches off the ground, jack up the axle just enough to allow you to put blocks under it. Now remove the wheels and fenders.
3. Next you’ll need two 24-inch long bars. Each bar may be a level, a square or any straight piece of iron bar. Clamp each of these bars tight to the face of each hub, centering them with the spindle.
4. As illustrated in Figure 2, first measure Line AD. Next measure Line BC. If these dimensions are equal, your hubs are square with the dolly, and you are ready to proceed with the toe-in adjustment (below).
5. If the dimensions are not equal, loosen the lock nuts on the end of Tube A and Tube B (Figure 1). Then, remove the six bolts in the center rod.
6. Rotate Tube A and Tube B as necessary to make Line AD the same length as Line BC. When these measurements are equal, the hubs are square with the dolly.
Then follow these instructions for Toe-In adjustment:
1. The dolly is designed to operate with 0" - 1/16" toe-in.
2. To adjust the toe-in, turn Tube A and Tube B (Figure 1) equally until Line AC (Figure 2) is between 0" and 1/16" less than Line BD (Figure 2).
3. Re-insert the six bolts, washers, nuts, etc. to the center rod.
4. Re-tighten the lock nut at the end of each tie rod.
5. Now re-measure to ensure that the measurements have not changed.
6. Re-assemble the wheels and fenders.
7. Torque all bolts according to the Bolt torque chart (Figure 3). Tighten lug nuts as shown on the Torque pattern for wheel lug nuts chart (Figure 4).
