Adjustment Preparation

1. Drive the vehicle on a hoist or an alignment machine. Ensure that the vehicle is at curb load level and the wheels are on a flat surface. Loosen the valve adjuster set-screw.
2. With a piece of rubber or vacuum hose or plastic tubing 3/8" outside diameter x 1/4 inch inside diameter, cut a piece .64" +/- .1" (16.3 mm +/- 0.3 mm). Slice the tubing lengthwise. See Fig 1 .
3. Place this length of tubing or hose on the valve operating rod. Make sure the adjuster sleeve is resting on the lower mounting bracket. Tighten the setscrew to specification. The dimension will position the valve for normal operation. Remove the tube or hose.
