Installation
1. If the weatherstrip material previously removed
is broken, weathered, or damaged in any way,
use new rubber weatherstrip material.
NOTE: Using a non-oily rubber lubricant on the
weatherstrip material and cab opening will make the
following installation easier:
a. Install the weatherstrip around the opening in
the cab for the glass. Start with one end of
the weatherstrip at the center, lower part of
the window opening and press the weather-
strip over the edge of the opening.
b. Continue installing weatherstrip while going
all the around the opening. When the ends of
the weatherstrip meet at the starting point at
the lower, center area of the window open-
ing, there must be 0.5 in. (12.7 mm) of over-
lapping material.
NOTE: The ends of the weatherstrip material need to
be square-cut to assure a proper fit.
c. Lift both ends so that they meet squarely,
then while holding ends together, force them
back over the lip of the opening.
2. Lubricate the groove of the weatherstrip where
the glass is to be seated.
a. Lower the glass into the groove along the
bottom of the opening.
b. Two people should be used for glass installa-
tion. Have one person on the outside of the
cab and push in on glass against opening,
while the person inside uses a soft flat tool
(plastic knife) and goes around the glass to
work the weatherstrip over the edge of the
glass.

3. After the glass is in place, go around the weath-
erstrip and push in on the locking lip (2, Figure
2-18 or 2-19) to secure the glass in the weather-
strip.
4. If windshield was being replaced, lower wind-
shield wiper arms/blades back to the glass.
