Place a spoonful of grease in the palm of one hand and
take the bearing in the other hand. Push a segment
of the wider end of the bearing down into the outer
edge of the grease pile closest to the thumb. Keep
lifting and pushing the bearing down into the edge of
the grease pile until grease oozes out both from the top
and from between the rollers. Then rotate the bearing
to repeat this operation on the next segment. Keep
doing this until you have the entire bearing completely
filled with grease.
NOTICE
Excessive grease in the hub or grease cap serves
no purpose due to the fact that there is no way to
force the grease into the bearing.
The
manufacturer’s
standard
procedure
is
to
thoroughly pack the inner and outer bearing with
grease and then to apply only a very small amount
of grease into the grease cap.
If bearing adjustment is required or the hub has been
removed for any reason, the following procedure must
be followed to ensure a correct bearing adjustment of
0.001 to .012 free play.
1.
While rotating hub slowly to seat the bearings,
tighten spindle nut to approximately 15 lbs.--ft.
Grasp the tire at the top and bottom and rock,
in and out. There should be no evidence of
looseness (free play) at the bearing.
2.
Loosen nut to remove preload torque. Do not
rotate hub.
3.
Finger tighten nut until just snug. Loosen nut
until the first nut castellation lines up with cotter
pin hole in spindle. Insert cotter pin.
4.
Ensure a definite but minimal amount of free
play by rocking the tire.
5.
Nut should be free to move with only restraint
being the cotter pin.
RECEIVER--SEPARATOR SYSTEMS
WARNING
High pressure air can cause severe injury or death
from hot oil and flying parts. Always relieve
pressure before removing caps, plugs, covers or
other parts from pressurized air system.
S
Open service valve at end of machine.
S
Ensure pressure is relieved, with BOTH:
-- Discharge air pressure gauge reads zero (0).
-- No air discharging from service valve.
When draining oil, remove plug from bottom of
separator tank.
When adding oil, remove and replace (make tight)
plug on side of separator tank.
In the compressor lubricating and cooling system,
separation of the oil from the compressed air takes
place in the receiver--separator tank.
As the
compressed air enters the tank, the change in velocity
and direction drop out most of the oil from the air.
Additional separation takes place in the oil separator
element which is located in the top of the tank.
Any oil accumulation in this separator element is
continuously drained off by means of a scavenge tube
which returns the accumulated oil to the system.
