Disassembly - Daewoo Solar 225LC-V Shop Manual

DISASSEMBLY

Refer to the assembly drawing of the swivel joint for component references (Figure 1).
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.
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 four 12 mm fasteners holding the cover. Use a vise or v-block to hold the assembly in
place.
4. Remove the cover, withdraw the O-ring and unbolt the fasteners holding the thrust plate, taking care
to support the stem (inner) assembly, so that it will not separate and fall out when bolts are
disconnected.
5. If the stem assembly doesn't separate easily when the thrust plate 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 tear down, 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.
The "backup ring" shown in the assembly drawing (above the swivel joint stem lower
NOTE:
seals) should not be overlooked. It is tucked behind the top slip ring, doubled up inside the
same groove in the body of the stem.
7. Before reassembling the center swivel, inspect ball bearing surfaces for visible signs of wear, damage
or discoloration and replace any worn component.
Check clearance between the cover and thrust plate, and between the stem and thrust plate.
Replace any component that shows more than 0.5 mm (0.020") of visible wear.
Clearance between the stem 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.
