Downloaded from www.Manualslib.com manuals search engine WHEELS AND TIRES 3F-3
Replacement Wheels
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated
bolt holes, if lug nuts won’t stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in “How to Measure
Wheel Runout” may cause objectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may
affect wheel and bearing life, brake cooling, speedometer / odom-
eter calibration, ground clearance to the body and chassis.
How To Measure Wheel Runout
To measure the wheel runout, it is necessary to use accurate dial
indicator. The tire may be on or off the wheel. The wheel should
be installed to the wheel balancer of the like for proper measure-
ment.Take measurements of both lateral runout (1) and radial
runout (2) at both inside and outside of the rim flange. With dial
indicator set in place securely, turn the wheel one full revolution
slowly and record every reading of the indicator.
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
Lateral runout limit
“a” : 1.20 mm (0.047 in.)
Radial runout limit
“b” : 1.20 mm (0.047 in.)
Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
: M12 x 1.25

into flange yoke.
5) Using round bar of 22 – 24 mm (0.87 in. – 0.94 in.) in diame-
ter and hammer, tap bearing races into shaft or flange yoke
until circlips can be installed in its groove on yoke bores.
6) Install 4 circlips in each groove on shaft and flange yoke
bores.
