assignments. The air pressure must be sustained.
7 Rotate the ratchet (item 29, Figure 1-5 on page 1-8 ) counterclockwise until one
tooth contacts the pin of the pawl and actuator stem assembly (item 18, Figure
1-4 on page 1-7 ). Secure the ratchet to the 0.25" diameter shaft of the carousel
spindle body (item 24, Figure 1-5 on page 1-8 ) utilizing the #6-32 x 0.125" long
socket set screw (item 12, Figure 1-4 on page 1-7 ).
8 Rotate the stop ratchet (item 31, Figure 1-5 on page 1-8 ) clockwise until it
contacts the stem of the pawl and actuator stem assembly (item 18, Figure 1-4
on page 1-7 ) as shown in Figure 4-2 . Secure the stop ratchet to the 0.25”
diameter shaft of the carousel spindle body (item 24, Figure 1-5 on page 1-8 )
utilizing the #6-32 x 0.125 long socket set screws (item 12, Figure 1-5 on page

page 1-8 ) as shown in Figure 4-3 . Pull the detent against the detent spacing
tool and subsequently against the tooth of the ratchet. Tighten the #2 fastener
(item 5,
Figure 1-5 on page 1-8 ) to secure the detent to the bellow assembly.
