Checking Windshield Opening
If it is suspected that the windshield opening has been
distorted through collision damage, or if the vehicle has a
history of windshield "strain breaks", the windshield
opening should be checked as follows:
1. Remove windshield, rubber seal and all foreign ma­
terial from windshield frame.
2. Place a new windshield glass in opening without
rubber seal.
3. Install checking blocks, Special Tool J - 9316, equally
spaced around perimeter of opening. Blocks may be
installed by inserting them between glass and metal
from outside of cab with the two notches toward in­
side of cab. Blocks are then rotated 1/2 turn so that
wide notch engages glass and narrow notch engages
pinchweld.

Installation

then examine opening flanges for irregular surface
which could cause glass breakage. Straighten flanges
if necessary.
2. Reposition rubber seal on flange. Raise new glass

stalled so that drain holes are at the bottom.

BODY VENTILATION

Outside air enters cab through a vent (fig. 97) directly
in front of driver and through the outside air heating sys­
tem. Air entry is made through a louvered, removable
panel, located in center of front end just above grille
opening. Air flows through plenum chamber between
outer and inner cab paneling and is dispersed to heater
or vent outlet as desired.
Figure 98 illustrates construction of fresh air ventilat­
ing assembly. For ease of operation, the spring, rod and
tube shown in View "A" should be lubricated with machine
or light motor oil whenever vehicle is lubricated.
