 MOUNTING WHEEL  IN   FIXTURE

Slide wheel on fixture bolt and suspend it by the edge of central hole centering taper detent.

Set nut lever in position RELEASE and push nut against wheel, as far as it will go. Resting

thumb on nut pin (as shown in Fig.15) move lever to the right, to position CLAMP and tighten

nut, preesing the whell against fixture disc.

Fig..15. Tightening nut

in order to remove wheel from fixture, rest index finger on nut pin (as shown in Fig. 16) and

loosen nut by one half turn. It may be then slid off the rod and the wheel may be removed from

fixture.
