With a hammer disengage the lug
that locks the ends of the rim together.
Then apply the rim tool, which is included
in the tool equipment. This is
done by hooking the U-shaped member
over the lug next to the valve stem, and
inserting the bolt through the holes in
the lug on the other side of the split in
the rim.
GENERAL INFORMATION 105
Caution in Adjusting Wheel Bearings
The adjustment of wheel bearings or the removal of the wheels should
not be attempted by one unfamiliar with work of this nature. It is recommended
that the car be taken to a Cadillac service station if possible. In
any event great care must be exercised in adjusting wheel bearings not to
get them tight. These bearings will revolve even when adjusted very tightly,
but that condition is sure to prove disastrous. They should be adjusted so
that a very slight amount of play or looseness may be discerned.
If, after a bearing has been adjusted to a point that is apparently correct,
the locking device cannot be placed in position without changing the adjustment,
it is far better to loosen the adjustment until it can be secured with the
locking device than to tighten the bearing adjustment.
Pull the handle of the tool up and
over as far as will go, thus drawing the
one end of the rim up over the other.
Figure 57.
The locking tongue can then be
placed back of the rivet as shown, and
will hold the rim in the split position.
The tire can then be forced off the
rim, using the "screw-driver" end of the
brace wrench.
After re-installing the tire, grasp the
handle of the tool, disengage the locking
tongue and allow the rim to return slowly
to position. After removing the tool, be
sure to drive the locking lug back into
place.
Removing tire from rim.
Removing Front Wheel
Figure 58. Front wheel bearings
To remove a front wheel, first jack up the axle until the wheel is free from
the ground and then proceed as follows:
Remove the hub cap by unscrewing it. Remove the cotter pin "E" (Fig.
58). Remove the lock nut "A." Remove the serrated washer "B." Remove
the adjusting nut "C." The wheel may then be removed by pulling it
straight off.
Installing Front Wheel and Adjusting Bearings
Before installing the wheel, make sure the bearings are clean and that they
are packed in a light grease that is free from dirt and grit.
Set the wheel in place on the spindle and adjust the nut "C" (Fig. 58)
very carefully, following the caution above. Install the serrated washer
