available, an ordinary coarse threaded tap of the proper size can be threaded into the
bushing, and with a bar whose
diameter is slightly less than the diameter of the hole and 1 inch longer
than the distance through the
steering knuckle, drive out
the tap and bushing.
To install new bushing, round
edges with a file; place in proper position with respect to knuckle to
align oil holes, noting that the oil
hole is nearer one end than
the other. Press into place with a vise or arbor press, taking care to start
bushing straight into the hole.
Do not hammer on bushing or
otherwise deform it.
After the bushings are in place,
they should be carefully reamed to
size, using a reamer long enough to reach through both bushings at
once, or preferably a reamer having a
long pilot bar which will just
pass through the opposite bushing while one is being reamed, the cutting flutes
also being long enough to finish both bushings together. Fig.
NOTE—When oversize kingpins are
installed it is necessary to ream the steering knuckle bushings first
with the reamer used for fitting a standard size kingpin, and then with
the special oversize reamer to fit the .010" or .020" oversize
kingpin, to provide .002" clearance between the kingpin and
