Assembly
1. Mark and tag all hoses.
2. Remove all hoses from Rotary Manifold.
3. Remove Rotary Manifold from the machine.
NOTE: Provide a clean work area for this operation, and observe clean assembly practices.
Seals and O-rings are highly sensitive to contamination that may not be visible to the naked
eye.
NOTE: Torque all hardware and fittings to torques
listed on pages 3-22 and 3-23 unless otherwise
specified.
1. Lubricate all seals with clean hydraulic oil prior to
assembly.
2. Install new seals on body and housing.
3. Carefully slide body into housing.

Disassembly
Installation
1. Remove Retaining Rings from each end of
Rotary Manifold.
2. Carefully slide body out of housing.
3. Remove seal kit components (O-rings, seals, and
retaining rings).
4. Thoroughly clean all parts with solvent. Rinse the
inside of the tube and allow to drain. A high pressure rinse and wipe with a lint free rag is preferable.
5. Inspect the body and housing for scratches, pits,
or polishing. Check seal grooves and sealing surfaces. Scratches or pits deep enough to catch the
fingernail are unacceptable, replace the manifold.
1. Installation is reverse of removal.
2. Replenish hydraulic fluid in tank.
3. Run hydraulic system for several minutes to
remove air from hydraulic lines. Cycle cylinders
