(2) clevis pins (Item 16) through holes in tubes.
Retain with (2) Hair Pins (Item 17).
2. Open and close hopper door to verify proper
operation.
ADJUSTMENTS
The Ultra Vac QDS was adjusted at the factory to
operate properly. However, there are three basic
adjustments that can be made, should the unit
require them:
1.
Arm Position:
The left and right bellcrank arms
control the timing of the left and right door
opening mechanisms. The ends of these arms
must be positioned equally from the upper frame
tube for proper actuation. Check this distance
with the door closed. If adjustment is necessary,
loosen the allen head clamping screw on the hub
of the right hand arm. Position the arms so
that their ends are the same distance from the
upper frame tube. Tighten the clamping bolt
to hold them in this position. See Figure 9.
2.
Door closing:
The closing of the door is
controlled by the two hinge links (Figure 10 – A).
The length of the hinge links can be changed to
provide complete closing of the door and
reasonable force on the handle to latch or
unlatch the door. Lengthen the links to reduce
the force. Shorten the links to increase the
force. The left and right sides must be
approximately equal. With the door closed, both
links should be slightly tight to minimize rattling.
3.
Door opening:
After adjusting the hinge
links for door closing, the hinge stops
(Figure 10 – B) can be adjusted to obtain
maximum door opening. The stop plates
should be adjusted so that the door link
contacts them when the upper tube of the
door frame is within .25” (6.4
mm) ± .125”
(3.2 mm) from the lower lip of the molded hood.
Both left and right stops must make contact
when the door link arm is at this position.
