grease No. 2 grade should be
added to bearings if they are dry,
although new bearings are norm-
ally pre-lubricated as received
from the source.
Place the assembly in position
with Power Ram J-6180 and Pump
J-6207 as shown in Figure 6-103.
Position the bearing straight over
the hole in the yoke. Carefully
pull up the spider so that the
spider journal enters the loose
bearing. With the pump, force the
bearing into the yoke continuing
to hold the spider up in this bear-
ing. Failure to do this could
cause the bearing needles to be-
come dislodged if the journal is
engaged incorrectly.
When the bearing is correctly po-
sitioned in the yoke, turn the as-
sembly over. Again place the
bearing over the hole in the yoke.
Carefully slide the spider parti-
ally out of the previously seated
bearing and start it carefully into
the bearing being installed. This
is to prevent the needles from the
bearing from burring the edge of
the spider journal if forced over
this journal other than straight.
Even slight burring of the journal
can cause premature failure.

Snap Rings
While pressing bearings into po-
sition, move the spider back and
forth to make certain that the
spider journals engage the bear-
ings squarely to avoid damage
and binding. If binding exists,
remove the bearings and spider
and examine for dislodged rollers
or damaged journals.
3. Observing the previous pre-
cautions, install the balance of
the bearings necessary to com-
plete the assembly, and install
snap rings.
4. Strike the yoke with a hammer
to f u l l y seat the snap rings
against the yoke. Turn the spider
to make certain that it is free.
See Figure 6-104.
b. Assembly of the
Ball Stud Seat
Examine the ball stud and ball
stud seats for scores or wear.
Worn seats can be replaced by
using a replacement kit, Gr.
5.442. Since the ball stud is an
integral part of the splined yoke,
any scoring of this part requires
the replacement of this splined
yoke. This assembly is also
available in kit form, Gr. 5.442.
1. Clean out the seat cavity thor-
oughly, then pack with Multi-
purpose Grease EP No. 1 Grade.
