7. Remove the lower kingpin bearing and seal
from the suspension yoke by inserting a 7/8" or
smaller flat-headed bar through the upper king-
pin bolt hole so it contacts the lower kingpin
plate. See
Figure 17
. Strike the top of the bar to
drive out the bearing. Do not remove the upper
kingpin bearing from the spindle yoke unless it
has been determined that replacement is nec-
essary. The upper bearing may be driven out by
the bottom of its inside edge using a chisel or
drift.
5.0 CLEANING AND INSPECTION
5.1 CHOICE OF CLEANING METHODS
1. Steam may be used for external cleaning of
completely assembled units. Care must be
taken to ensure that water is kept out of the as-
sembly by tightly closing breather caps and
other openings.
2. Rough parts such as housings, which are too
large to conveniently clean with solvents, may
be immersed in a hot solution tank containing a
mild alkaline solution. Parts cleaned in hot solu-
tion tanks must be rinsed thoroughly to prevent
damage by traces of alkaline material.
3. Parts with ground or polished surfaces, such as
bearings or shafts, should be cleaned with
emulsion cleaners or petroleum solvents. Alka-
line hot solution tanks may damage the ma-
chined surfaces and should be avoided.
5.2 DRYING AND CORROSION
INHIBITION
Soft clean shop towels should be used to dry parts after
cleaning. Compressed air may be used to clean accessi-
ble areas of large parts such as the housing. Bearings
should not be spun dry with compressed air as the lack of
lubrication may cause damage to the mating surfaces.
Dry parts should be immediately coated with a light oil or
a corrosion inhibitor to prevent corrosion damage. Parts
which are to be stored should also be wrapped in heavy
waxed paper.
5.3 INSPECTION
Prior to reassembly, parts which are to be reused must
be carefully inspected for signs of wear or damage. Re-
placement of such parts can prevent costly downtime at a
future date.
All bearing and bushing surfaces including roller bearing
cups and cones should be examined for pitting, wear, or
overheating. Shafts may be nicked and marred or have
damaged threads. Inspect all structural members and
welds closely for any signs of cracking. Parts which show
any sign of damage should be repaired or replaced.
