LIGHT DUTY
TRUCK
(Series 10-35)
SHOP MANUAL
These vehicles contain some parts dimensioned in the metric
system as well as in the customary system. Som e fasteners are
metric and are very close in dimension to familiar customary
fasteners in the inch system. It is important to note that, during
any vehicle maintenance procedures, replacement fasteners must
have the same measurements and strength as those removed,
whether metric or customary. (Numbers on the heads of metric
bolts and on surfaces of metric nuts indicate their strength.
Customary bolts use radial lines for this purpose, while most
customary nuts do not have strength markings.) 'Mismatched or
incorrect fasteners can result in vehicle damage or malfunction, or
possibly personal injury. Therefore, fasteners removed from the
vehicle should be saved for re-use in the same locations whenever
possible. Where the fasteners are not satisfactory for re-use, care
should be taken to select a replacement that matches the original.
For information and assistance, see your dealer.
