Door and Door Hinge Seal Replacement
1. The door assembly seal has only three mem-
bers to it (sides and top) and is glued on the
door. This seal can be replaced by peeling the
seal away from the door frame. Then use a
suitable cleaner to remove the remaining seal
and glue material.
2. The area where the door seal mounts should be
free of dirt and oil. Spread or spray a glue which
is quick drying and waterproof onto the area
where the seal is to installed.
3. Install the seal so that the corners of the seal fit
up into the corners of the door frame (3, Figure
2-16).
4. The Door Hinge Seal is glued to the hinge. Use
the same procedure as above for this seal (2,
Figure 2-17).
Door Opening Seal Removal
1. Starting at the lower center of the door opening,
pull up on one end of the seal. Seal should pull
loose from the cab opening lip. Pull seal loose
all the way around the opening (1, Figures 2-16
& 2-17).
2. Inspect cab opening lip for damage, dirt, or oil.
Repair or clean cab opening as necessary.
Remove dirt, old sealant etc. Be certain perime-
ter of opening is clean and free of burrs, etc.
Installation
1. Install the seal material around the door opening
in the cab. Start at the bottom center of the cab
opening and work the seal lip over the edge of
the opening. Go all the way around the open-
ing. Be sure that the seal fits tight in corners. A
soft face tool may be used to work the seal up
into the corners.
2. Continue going all the around the opening.
When the ends of the seal meet at the starting
bottom center of the cab opening, it may be
necessary to trim off some of the seal.
NOTE: The ends of the seal material need to be
square-cut to assure a proper fit.
3. Fit both ends so that they meet squarely, then
while holding ends together, push them firmly
into the center of the opening.
