Caster, Camber, Tow-Wheel Alignment

What is a caster-Camber-Tow-Wheel alignment

First of all, I will explain for those who do not know casters, cambers, and towins. The casters show how the wheel is associated with a vertical kingpin or ball joint. It can be true vertical or -o-degree, positive, or negative. Example: The front wheel of the bicycle has positive casters. Notice that the wheel extends forward from the axis of rotation. Therefore, the steering can return straight when you take your hand off the handlebars. You can do the same with vehicles on positive casters. This adjustment is for handling or driving methods and requires a camber gauge for adjustment and a specific hand wrench.

Camber indicates the position of the wheel with respect to the vehicle. For example, from top to bottom (negative), from top to bottom (positive). The recommended settings are negative 1 to positive 1, -0 degrees straight up and down, or true vertical. In extreme cases with either method, the middle or outer edges of the tire may wear and scallops may form. This adjustment is for tire wear and, in some cases, handling. In addition, certain tools such as the upper control arm wrench and the Tomcat camber adjustment tool may be useful.

After the casters and camber are set, we go tow. This is also due to tire wear and probably some handling. Towing is the adjustment relationship between the left front wheel and the right front wheel. If the front tires are slightly facing each other, it is towing. If they are separated from each other, it will be towed. Before making this adjustment, you need to set the steering center. This is the relationship between the steering wheel and the left front wheel. Set the steering wheel straight forward (center) and pull the left wheel slightly or about 3/16 inch. This can be done using strings. It is pulled out from around the left rear wheel, pulled forward with the rear wheel as a guide, and a straight line is drawn on the left front wheel. Therefore, allowing the string indicates where the left front wheel is towed or towed. You need to adjust the left wheel first and the right foot wheel to the left wheel so that the toe-in is about 1/4 inch. There are traction adjustment tools such as traction adjustment bars and tie rod spreaders. , And tie rod kit. This will help you do this alignment.

A single shim or adjustment to move the rear of the control arm outward may give the wheel the proper settings if you understand what happens in both settings (casters and camber) at the same time. .. In addition to that knowledge or understanding, proper hand tools and some experience are all that really need. Well, maybe a good coach will come in handy. However, returning to the movement made by adding a single shim to the back of the upper control arm (the shims have different thicknesses), there are fewer negative casters and more positive camber. I hope this helps. Any questions?Rem Void
