STEMCO Qwik Kit King Pin Repairs - Manual

REMOVAL
• Use established procedures for teardown. It is not
necessary to remove the steering knuckle from the truck
to install a STEMCO Kaiser QWIK KIT™.
STEERING KNUCKLE AND AXLE
PREPARATION
• Clean spindle bores and axle eyes then wipe dry.
• Remove any burrs from spindle bores and axle eyes
using a brake hone or similar device.
INSTALLING BUSHING LIP SEALS
• Handle with care, lip seals are easily damaged.
• Using a bushing driver or similar device, drive the seal
into the bore, leaving the seal flush with the axle side
of each spindle.
• Be sure to position the seal so the lip is pointing
towards the axle eye. (see figure #3)
INSTALLING SPIRAL STEEL BUSHINGS
• Place the tip of the bushing
at a slight angle to the bore.
With a push-in, clockwise
twisting action, the bushing
will enter the bore. Continue
with the twisting action as
far as the hand grip will
permit. (see figure #1)
• Grip bushing wall with a "T"
wrench or pliers about 1"
from the tip. Continue the
clockwise rotation as far as
possible. (see figure #2)
• Tap bushing into the bore
until slightly below flush
using a brass mallet.
CHECK BEFORE ASSEMBLY
• Wipe the bushing clean. Insert the king pin into just the
upper bushing, then into just the bottom bushing. In
both cases the pin should be a slip fit. Then insert the
pin into both bushings simultaneously and again the
pin should be a slip fit. If at any time during this test the
pin becomes tight, remove the bushing or bushings
and use a brake hone to thoroughly clean the bores
again. If upon reinstallation the pin is still tight, call
technical service.
BEARING INSTALLATION
• Pre-pack bearing with grease.
• Opening on bearings outside diameter should point
down. (see figure #3)
• Place needed shims under upper spindle bore.
• Position king pin through upper bushing and through
needed shims. Be sure TOP on pin is parallel to axle for
proper lock flat alignment.
• Place spindle, shims and pin onto axle, allow pin into
axle bore about 2".
• Tap bearing into place. A properly fit
bearing will require a slight tap fit with
out damaging the bearing case.
• If bearing is too tight or too loose, adjust
number of shims being used.
•Once bearing fit
is correct allow
pin to slip into
lower bushing.
• Position lock flats on pin so
they line up with lock holes.
• Pound lock pins into place, for lock
pins with threads apply 25-30 ft. lbs of torque
END PLATE OR END PLUG INSTALLATION
• Install end plates or end plugs, use proper seal under
plates
• Install grease fitting into end plate or end plug
GREASING
• Apply grease until it can be seen between axle and
spindle. Then turn spindle and grease again repeating
the process 5 times
CHECK INSTALLATION
• Once greased the spindle should turn easily from side
to side.
• There should be very little up and down movement.
