• 7/16" Open End Wrench
1. Remove the rear wheels.
2. Remove the camber tube. See "Replacing the
Camber Tube (Evo)" on page 61.
3. Remove the four Allen Screws (two on each side of
the chair) that secure the adjustable axle plates to
the frame. Carefully note the order in which the
various washers and nuts (and any other parts, such
as anti-tip receptacles) were originally installed on
your chair as you will need to reinstall all of these
parts in the exact same order in Step 5 below. See
Figure 72.
4. Reposition one adjustable axle plate to desired
height, making sure that one hole at either end of
the axle plate aligns with one hole in the frame.
Note that the holes in the frame are spaced in 1"
increments and the holes in the adjustable axle
plate are spaced in 1/2" increments, making the
height adjustable in 1/2" increments. Also note that if
your chair is equipped with armrests and/or anti-tips,
you may need to raise or lower these by the same
amount you raise or lower the adjustable axle plate.
