Replacing Camber Inserts Figure, Rear Wheels

REAR WHEELS

PROCEDURE 4

2.Measure the distance between the center lines at the rear and front of the rear wheels at approximately 12- inches from the ground/floor (FIGURE 3).

NOTE: For optimum accuracy, perform STEP 2 with the wheelchair occupied.

3.Determine the difference between the two (2) mea- surements. If the difference between the two (2) measurements is GREATER than 1/2-inch (0 + 1/ 4-inch for maximum rollability), one (1) of two (2) conditions exists:

a.If the back centerline measurement of the rear wheels is SMALLER than the front centerline measurement of the rear wheels, a TOE-OUT condition exists (FIGURE 3).

b.If the back centerline measurement of the rear wheels is LARGER than the front centerline measurement of the rear wheels, a TOE-IN con- dition exists (FIGURE 3).

4.If the difference between the measurements is greater than 1/2-inch, correct the toe-in/toe-out condition. Re- fer to ADJUSTING TOE-IN/TOE-OUT in this proce- dure of the manual.

FIGURE 3 - DETERMINING/ADJUSTING TOE IN/TOE OUT

Adjusting Toe In/Toe Out

1.Loosen, but do not remove the socket screws and clamps that secure camber inserts to the camber bar.

2.Slowly rotate the camber insert until the rear wheels are approximately in a straight line.

3.Securely tighten the socket screws and clamps that secure the camber inserts to the camber bar.

4.Measure the distance between the center lines at the rear and front of the rear wheels at approximately 12- inches from the ground/floor. Refer to DETERMIN- ING TOE IN/TOE OUT in this procedure of the manual.

5.Repeat STEPS 1-4 until the toe in/toe out measure- ment is less than 1/2-inch (0 + 1/4-inch for maximum rollability).

REPLACING CAMBER INSERTS (FIGURE 4)

1.Loosen, but do not remove the socket screws and clamps that secure the camber inserts to the camber bar.

2.Remove the existing camber insert from the camber bar.

3.Install the new camber insert into the camber bar.

4.Adjust the toe in/toe out of the wheelchair. Refer to DETERMINING/ADJUSTING TOE IN/TOE OUT in this procedure of the manual.
