Vinyl Coated Cloth
To clean the seats, use lukewarm, not hot or
cold water, and any mild soap, such as castile.
Work up thin suds on a piece of cheesecloth and
rub upholstery briskly. Remove suds with a damp
cheesecloth, using no soap, and finish by rubbing
with a dry cloth. Do not use furniture polishes,
oils, varnishes or ammonia.
Woven Nylon Fabric
Soap and water, regardless of the basic type
of soap, is not recommended for cleaning nylon
fabrics of the type used on these vehicles.
1. Carefully brush all loose particles of dirt
and soil.
2. Immerse small cloth in volatile type clean­
ing solution, wring out thoroughly, open cloth and
allow medium evaporation.
Do not use too much cleaning fluid; some in­
terior trim assemblies are padded with rubber,
and volatile cleaners are generally solvents for
rubber. The application of too much cleaner may
destroy these rubber pads or cause the rubber it­
self to penetrate the upholstery fabric and soil it.
3. Place cloth on soiled spot, do not rub, apply
slight tapping pressure, several times. This will
pick up particles which are too embedded to be re­
moved in the brushing operation. This operation
should be repeated several times - in each instance
using a clean area of cloth.
4. Immerse a new cloth in cleaner, wring out
thoroughly, open and allow to evaporate until bare­
ly damp. Apply increased pressure and rub soiled
area in a backward and forward motion. The clean­
ing cloth should be reversed several times in this
operation.
5. Immerse third cloth, wring out, allow evap­
oration and apply to both the soiled and the area
surrounding same, using a light, brisk motion.
6. Repeat brushing operation.
7. If a cleaning ring should form, the entire
area of the assembly which is being cleaned should
be thoroughly brushed and gone over lightly with
the solvent.

(F U L L - W ID T H TYPE)
If right-hand and left-hand seat adjusters do
not release simultaneously, lengthen or shorten
adjuster lock rod underneath the seat assembly.
A stud adjustment nut and wing nut at ends of
seat-back frame (fig. 4) provide a means of chang­
ing tilt of seat-back. To change tilt of seat-back,
loosen each wing nut and turn adjustment nuts
above seat-back frame brackets an equal amount
to raise or lower seat-back. Tighten wing nuts to
secure desired position.
SEAT TRACK REPLACEMENT
N O T E : The seat track assemblies are more
readily replaced after seat assembly is removed
from cab.
1. Remove four screws which attach each
track assembly to seat cushion. Lift seat assembly
from cab.
2. If only one track assembly is to be remov­
ed, disconnect lock rod between tracks, then re­
move four bolts which attach each track to cab
floor panel. Remove track assembly.
3. Reverse the above procedure to install
track assembly.
