Rotate the pin. The pin should be pointing upward to the 12 o'clock position. Refer to Illustration 2.

Push the mounting pin fully back into the frame.

Check the shimming of the axle end float within the frame. Add additional washers to the axle if necessary, in order to obtain a maximum gap of 0.8 mm (0.03 inch). Ensure that the washers are equally positioned on each side of the axle.
Note: If the pin must be removed, make sure that the pin is installed pointing in the upward position.

Remove the existing boss for the retaining bolt by using a grinder.
