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 at the lower center
of the cab opening and press the weatherstrip
over the edge of the opening (3 & 4, Figure
2-18).
b. Continue installing weatherstrip while going all
the around the opening. When the ends of the
weatherstrip meet at the starting lower center
of the cab opening, there must be 0.5 in. of
overlapping 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 (1 & 4, Figure 2-18).
Note: Two persons should be used for the
following installation:
b. Have one person on the outside of the cab 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 to secure the
glass in the weatherstrip (2, Figure 2-18).
4. If windshield was being replaced, lower wind-
shield wiper arms/blades back to the glass.
