LIGHT DUTY
(SERIES 10-35)
CHASSIS SERVICE
MANUAL
These vehicles contains some parts dimensioned in the metric
system as w ell as in the customary system. Some fasteners are
m etric and are very close in dimension to familiar customary fast­
eners in the inch system. It is im portant to note that, during any
vehicle maintenance procedures, replacement fasteners must
have the same measurements and strength as those removed,
w hether m etric or customary. (Numbers on the heads o f 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.
