glass lifters (see
Service Tools
).
b

approximately 1 to 2 mm on the upright face of the cab
frame aperture, as shown at
J
.
6
Apply a coat of 'Black Primer 206J' to the paintwork if:
a
Paintwork was damaged or scratched during the
glass/sealant removal procedures.
b
The old sealant was inadvertently cut back to the
cab frame during the glass/sealant removal
procedures.
Preparing the Cab Frame Aperture
1
If damp or wet, dry the aperture area using a hot air gun
(sourced locally).

Use 'Active Wipe 205' to thoroughly clean and 'prime'
the trimmed sealant. Use a lint free cloth to apply the
'Active Wipe 205', allow 5 minutes flash off (drying)
time.
Note:
Do not use any other type of cleaning fluids, otherwise
they may be absorbed into the old sealant and ultimately
prevent the new glass from bonding.
