BARFIELD JOINT CONSTRUCTION AND OPERATION
The major parts of the Barfield joint are the outer race (integral with wheel spindle, to which the wheel
disc is splined), inner race (splined to the live axle shaft), six steel balls disposed between the two races,
and cage (holding the steel balls in a single row lying in a plane).
Spindle shaft
IInner raceSteel ball
The balls are fitted in two groups of raceways; one group is on the outer race and the other group on the
inner race. Each ball is in its own raceways as if it were locked between the two races in the direction of
rotation. The outer race with its wheel spindle is capable of angling and, when it so angles with respect to
the axis of axle shaft, the row of steel balls angles just half as much, that is, the plane including this row
tilts by an angle equal to one-half of the spindle angle. This relationship is illustrated in Fig. 17-1-4.

Barfield Joint
To be checked on this joint is its axial play,
which shows up when a push-and-pull motion is
given to live axle shaft and wheel spindle held in
both hands, as shown in figure. There should be
no play at all but a play of up to 1.5 mm (0.06
in.) is permissible. If play exceeds service limit,
replace it.
\/
Leaf Spring Bushes
Inspect for wear and breakage. If found defec-
tive, replace.
Front Wheel Bearing
Check front wheel bearing rollers for damage.
If anything is found wrong, replace bearing with
a new one.
