NOTE: Be sure to mark an index point on the case and spool to insure proper
reassembly.
INSPECTION AND SEAL REPLACEMENT
1.
The “case” bore should be thoroughly washed with solvent or diesel fuel and
inspected for signs of “scoring” or deep scratches. This type of damage is generally
caused by the presence of foreign material in the hydraulic system. No satisfactory
method of repairing this type of damage can be conducted in the field.
2.
The “spool” should be carefully washed in solvent or diesel fuel. The seals and “O”
rings should not be removed from the spool unless they show signs of wear or
damage. NOTE: If the seal is removed for any reason, it should be replaced since
removal will almost always damage it beyond use.
When installing a new seal and ring, it must be “walked” into place past other seals and oil
grooves and then into its own groove in the same manner that the bead of a tire is “walked”
into the wheel rim. The spool should be well oiled to aid in this assembly. Best results can
be achieved if the spool, with the seals mounted on the end, is allowed to sit overnight.
This gives the seals a chance to adjust to normal size.
REASSEMBLY
1.
The top and bottom “O” rings and back-up washers can be replaced without removing
the spool. Removing the top cover exposes the top “O” ring. The spool will drop out of
the case, exposing the bottom “O” ring.
UPON REASSEMBLY, INSTALL THE UPPER “O” RING AND BACK-UP RING
AFTER THE SPOOL IS IN THE CASE. THIS WILL PREVENT ANY DAMAGE
WHICH MIGHT RESULT FROM SLIDING PAST PORT OPENINGS.
2.
The rotary manifold should be reassembled using a generous coat of oil on the case
ID and spool OD. Generally, reassembly is most successful by placing the case in a
vertical position and inserting the spool into the case. Each seal and wear ring should
be compressed by hand to initially enter the case bore. With the spool fully inserted
into the case, the assembly may be “up-ended” to replace the end plate.
3.
Ports should be properly protected, capped, and, preferably, oil filled without pressure.
NOTE: If the rotary manifold is oil filled and plugged, ample air space should be
allowed for the expansion of oil due to temperature changes.
IT IS IMPORTANT THAT THE SPOOL FLOATS FREELY WITH THE CASE TO
PREVENT WEAR AND LEAKAGE. THE SPOOL IS HELD STATIONARY WITH
RESPECT TO THE LOWER BY A RESTRAINING BRACKET DESIGNED TO
ALLOW FOR SOME ECCENTRICITY. THE ROTARY MANIFOLD SHOULD BE
SHIMMED AT THE MOUNTING EARS AS NECESSARY TO INSURE
CONCENTRIC ROTATION. ROTATE THE MACHINE WHILE VISUALLY
CHECKING THE ALIGNMENT. THE BRACKET MUST NOT BIND DURING
ROTATION.
