3. Loosen and vertically align (center) the door
jamb bolt with this mark and tighten it firmly
enough to hold it in place but still allow some
slippage.
4. Carefully try to close the door (4) and determine
if this has helped the "springing" problem. If the
door latches but not firmly enough, follow proce-
dures listed previously in "Step A". If the door
latch does not catch, move the bolt outwards
and try again. When corrected, follow adjust-
ment procedures listed in "Step A" to ensure a
good seal. By design, if both seals are in good
condition, proper adjustment of the outside seal
will ensure good contact on the inside seal to
prevent dust and moisture from entering the
cab.
