AND RETRACTING
VAN BODIES
(M447,
M447C,
M749, AND M750)
(Cont).
NOTE
Bottom of side panels are identified by edge containing deflector strip and seal.
(4)
Position side panels,
in numbered
order, leaning against opened
lower side doors with bottom of
side panels facing down.
WARNING
Clean up ail excess solutions or compounds from extrusions and side panels. Failure to
do so could result in slippery surfaces which could result in injury to personnel.
NOTE
If silicone
compound
is not readily
available,
a solution
of soapy
water
may be
substituted.
(5)
Apply silicone
compound
(Item 12, Appendix
E) to rubber seals of side panels to ease installation.
(6)
While facing ends of opened side doors, raise first panel into position.
Leave about 1 in. (2.54 cm)
between
body post and side panel so pin on lower body door will enter clearance
hole at bottom of side panel.
(7)
Tilt top of side panel inward until it contacts
rubber seals along end of upper side door.
(8)
Push upward and inward on side panel until side paneI is seated along top and bottom.
(9)
Slide side panel toward body post until pin in lower door engages
hole in bottom of side panel.
CAUTION
Ensure that hexagonal
wrench
is fully engaged
in male lock. DO NOT, under any
circumstances,
force engagement
of male lock into female lock. Tighten locks only
until a moderate
positive
pressure
is obtained.
Any attempts
to pull side panels
together
will only shear teeth of male lock or pull it out of position.
NOTE
If engaging corner locks is difficult, grasp edge of upper side door and pull downward
while locks are engaged.
This causes weight of side panel to be partially transferred
from lower to upper door through counterbalance
system. This in turn causes upper
door to deflect down enough to center locks. With clearance
at top and bottom doors
equal, corner locks along sides of doors may be tightened.
(10)
Remove locking wrench from jack storage box. Use wrench to partially engage male lock in mating
case of end panel. Partially engage male locks on body post to mating cases in side panel.
(11)
Male locks near outer ends of upper door and lower door should be partially engaged
in their mating
cases in side panel.
(12)
While facing open van, lift up second side panel and position it as close as possible to previous side
panel.
(13)
Tilt top of side panel inward until side panel contacts
rubber seals along end of upper side door.
(14)
Ensure that pins aline with clearance
holes at bottom of side panel. Push upward and inward until
side panel is seated top and bottom.
(15)
Partially engage locks along upper edge of side panel, then partially engage locks along
previous
side panel and finally along lower edge.
(16)
Loosen and/or tighten locks along previous side panel, until clearance
is X2 in. (2.38 mm) between
two side panels.
