Due to the severe duty application of off-highway
vehicles, the cure times listed by the adhesive
manufacturer should be doubled before a truck is
moved. If the cure time is not doubled, vibration
or movement from a moving truck will weaken
the adhesive bond before it cures, and the glass
may fall off the cab.
If another adhesive manufacturer is used, be cer-
tain to follow that manufacturer's instructions for
use, including the use of any primers, and double
the allowances for proper curing time.

Replacement Procedure
The first concern with all glass replacement is
SAFETY! Wear heavy protective gloves and
safety eyeglass goggles when working with
glass.
1. Using chosen cut-out tool, slice into existing
urethane adhesive and remove window.
2. Carefully clean and remove all broken glass
chips from any remaining window adhesive.
The surface should be smooth and even. Use
only clean water.
NOTE: Removal of all old adhesive is not required;
just enough to provide an even bedding base.
3. Using a long knife, cut remaining urethane from
vehicle, leaving a bed 2-4 mm thick. If existing
urethane is loose or otherwise unsound, com-
pletely remove. Leave the installation bumpers
in place, if possible. Clean metal with Sika Akti-
vator, allow ten minutes to dry. Then paint on a
thin coat of Sika Primer 206G+P and allow ten
minutes to dry.
4. Using only the new side window(s) which are to
be bonded in place, center the new glass over
opening in the cab. Using a permanent marker,
mark on the cab skin along all the edges of the
new glass that is to be installed. All edges must
be marked on the cab in order to apply the
adhesive in the proper location.
5. Using Sika Primer 206G+P, touch up any bright
metal scratches on the metal frame of vehicle.
Do not prime existing urethane bed. Allow to dry
for ten minutes.
