Rear Wheel Rubs on the Side Frame

Cause 1: Your RoughRider will pull to one side if the axle bolt is loose. If the axle bolt is loose in

the axle block, the weight of the rider on the seat will cause the wheels to lean in at the top. If they

lean far enough, the wheel might rub against the side frame, friction will act like a brake on the

wheel and cause your RoughRider to turn toward that side.

Frame is Misaligned

If one of the side frames leans inward while you are riding the chair, the chair may turn away from

that side. The side frame of the chair leans inward when the ends of the seat tube on the same side

of the chair are bent inward.

Solution: This repair requires two people. Clamp the square tube (cross tube) in a vise . Slide two

long (50-80cm) strong, thick- walled tubes over the ends of the bent seat tube until they are both

touching the square tube. At the same time, both people should carefully push (or pull) in the

opposite direction that the seat tube bent. Continue until the seat tube is straight. Hammering the

ends of the seat tube outward can correct the problem. If the side frame bends inward again, get a

good welder to re-align the entire X-brace and reinforce both seat tubes by welding in reinforcing

rods under the seat tube.

Reinforcement Welded

Under Seat Tube

Solution: Tighten the axle bolt. Replace any missing washers or

nuts. If the hole in the axle socket ha

loose, move your wheels to a different axle position.

Cause 2: The wheel is bent. If the wheel rim is bent, you can usually fix

it by adjusting the spokes.

Solution: Adjust and tighten the spokes as shown in Spokes section. If

the wheel rim is bent a lot, you must straighten it before adjusting the

spokes.

Cause 3: The axle block is bent relative to the frame.

Solution: Re-align axle block as shown in Rear Axle is Out of Alignment section.
