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. Bend over cotter pin legs to secure nut and
clear grease cap.
6. Nut should be free to move with only restraint
being the cotter pin.
7. Inspect Leaf Springs and Retaining Bolts/Nuts.
RECEIVER--SEPARATOR SYSTEMS
WARNING
High pressure air can cause serious injury or
death from hot oil and flying parts. Always relieve
pressure before removing caps, plugs, covers or
other parts from pressurized air system.
* Open service valve and manual blowdown valve at
end of machine.
* Ensure pressure is relieved, with BOTH:
-- Discharge air pressure gauge reads zero
(0).
-- No air discharging from service valve or
manual blowdown valve.
* When draining oil, use valve at 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 com-
pressed 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.
The life of the oil separator element is dependent upon
the operating environment (soot, dust, etc.) and
should be replaced every twelve months or 2000
hours. To replace the element proceed as follows:
* Ensure the tank pressure is zero.
* Disconnect the hose from the scavenge tube.
* Remove scavenge tube from tank cover.
* Disconnect service line from cover.
* Remove (20) cover mounting screws.
* Remove cover, element and inner shell.
* Remove any gasket material left on cover or tank.
* Install new gasket, inner shell and new element.
NOTICE
Do not remove staples from the elementgasket.
The staples provides continuity between the mat-
ing components.
