Center Joint (Swivel)
DISASSEMBLY
Refer to the assembly drawing of the swivel joint for component references (Figure 1).
1.
Clean off the exterior of the swivel joint after it has been removed.
2.
Scribe or otherwise mark a line across the cover and the body of the center joint, to allow reassembly
in the same configuration.
3.
Unbolt the three 8 mm fasteners holding the cover. Use a vise or v-block to hold the assembly in
place.
4.
Remove the cover, withdraw the spindle.
5.
If the spindle doesn’t separate easily when cover and fastener bolts are removed, use a wooden
block and hammer to drive it out of the housing.
6.
O-rings and seals should be replaced whenever the assembly is being overhauled or rebuilt. For
repair procedures or emergency teardown, use a thin but rounded-tip, smooth-edge scraper or
spatula to remove O-rings or seals, to avoid causing damage to those that must be reused.
NOTE:
The O-ring (10E) shown in the assembly drawing (above the swivel joint stem lower seals)
should not be overlooked. It is tucked behind the top slip ring, doubled up inside the same
groove in the body of the Center Joint.
7.
Before reassembling the center swivel, visually inspect ball bearing surfaces for visible signs of wear,
damage or discoloration and replace any worn component.
Check clearance between the spindle and thrust plate. Replace any component that shows more
than 0.5 mm (0.020") of visible wear.
Clearance between the spindle and body of the center swivel must be tight. Replace or repair either
component if there is more than 0.1 mm (0.0039") of measurable wear.
REASSEMBLY
1.
Pre-lubricate O-rings with hydraulic oil, white grease or petroleum jelly.
2.
Thoroughly clean all other component surfaces of dirt or grease prior to reassembly.
3.
Reverse disassembly steps for reassembly.
IMPORTANT
Do not unbolt the center joint from the lower car body until an adequate number of piping block-
off plates are available, for disconnected piping lines. Be sure that system pressure has been
vented - including the hydraulic accumulator and tank reserve pressure - before disassembly is
started.
CAUTION!
Apply a very light film of white grease or petroleum jelly to the lower rim of the spindle and
inner surface of the center swivel body. Apply slow, even-handed pressure, using both
hands, to slowly push the spindle into the body. Seals may be damaged if the spindle is
pushed in too quickly.
