REPAIR HELP TRUING PROCEDURE The procedure described here emphasizes lateral true, which most affects the caler brake. The idea is to get the wheels true enough to avoid hitting the brake pads. The other aspects of truing such as radial, centering and tension are ant. For the novice mechanic, it is best to begin with lateral true in order for the brakes to work properly. The image below is a “mechanic’s eye” view of the rim. The spoke nples labeled A, C, and E are on the left side of the rim and come from the left side flange. Spoke nples B, D, and F are on the right and come from the right side flange. Left side spokes tend to pull the rim toward the left. Their pulling is offset by the pull of spokes on the right. Each nple effects relatively wide area of the rim. For example, spoke C will pulls mainly adjacent to its location, but will also effect the rim up to and even past A and F. Tightening nple C increases spoke tension and moves that section of rim to the left. Tightening nple D will tend to move the rim to the right. Loosening nple C will also tend to move the rim to the right, because on the constant pull of D. In order to see rim movement, a steady pointer is useful as a reference. A wheel-truing stand allows easier and more accurate work. It is also poible to use anything that can hold the wheel steady as a truing stand, such as the frame. A pointer can be created by using the brake pads. Radial truing and rim centering are typically not an iue when only minor corrections are made. It can help to remove the tire while truing. Remove wheel from bike and remove tire. (NOTE: for lateral truing, the tire can remain in place.) Mount wheel in truing stand, with right side of the wheel on the right side of the stand. Lubricate the threads of the spokes and where the nple exits rim.

Bring calers up to rim level. Generally, place caler ts close to outer end of braking surface. Spin wheel. Adjust caler close to rim. Keep moving caler until either side begins to lightly se rim. Only a light s is desired, bring caler slightly away if sing heavily. Stop wheel where rim and indicator are closest, at the point of the se. Rotate rim back and forth past caler and find center of rim deviation. If the rim deviation is moving toward the indicator, this section of rim needs to move away from caler.

A. IF RIM TOUCHES LEFT SIDE CALER, FIND CLOSEST NPLE TO CENTER DEVIATION COMING FROM RIGHT SIDE OF HUB FLANGE.

B. IF RIM TOUCHES RIGHT SIDE CALER, FIND CLOSEST NPLE TO CENTER DEVIATION COMING FROM LEFT SIDE OF HUB FLANGE. Tighten nple 1/2 turn. Move wheel back and forth in this area and check deviation again. Spin wheel and locate another side-to-side deviation using indicator. Again slow and stop the rim where rim approaches indicator. Locate closest nple opposite to center of deviation tighten nple. If nple appears especially tight, loosen spoke on same side as rub on indicator. Repeat until wheel is true. Wheel is adequately true if it wobbles le than 1/16” (1.0mm). Clean rim braking surface with a soent such as rubbing alcohol or a window cleaner. RADIAL TRUING The wheel rim may appear to move in and out toward the center. Another way to view it is up and down. This radial aspect of the wheel can be affected by spoke tension. Sections of rim can be moved toward the hub by tightening spokes. Alternatively, sections of rim can move slightly outward by loosening spokes. It is typically best to work using pairs of spokes. By working with adjacent left-right spokes there is le of a tendency for the wheel to become laterally out of true.

Remove wheel from bike and mount in a truing stand. Bring caler close to lower outside edge of rim. Spin rim and bring calers slowly closer to rim until there is a very light rub. Stop rim a light rub. Move rim back and forth through rub and locate center of deviation. This section of rim is relatively further from the hub than the rest of the rim. It needs to move closer to hub. Tighten the two spokes in the middle of the rub. Tighten each the same amount, beginning with 1/2 turn. Move the rim back and forth through the selected area. Repeat tightening if neceary. Spin the rim and move the calers slightly closer to the rim. Correct rub by tightening a left-right pair at the center of the rub. After making three radial corrections, stop and double check lateral true. Correct lateral true as needed. After making several radial corrections by tightening, the rim may show only areas moving toward the hub. It is neceary to loosen these area to make the rim rounder. Spin the rim and move caler for a light continuous se. The area not sing are called low spots, or ds, and need to move away from the hub to be corrected. Isolate the center of the worst low spot Loosen two spoke on either side of the center of the low spot. Spokes should be adjacent left side-right side pairs. Repeat procedure on other low spots. Wheel is adequately trued for round when the deviation from the low spot to the highest spot is about 1/32 of an inch (about 0.5mm) NOTE: If the wheel rim has been damaged and deformed from impact, such as during riding or even hping, it may not be poible to correct the rim to a tight tolerance.
