If the hydraulic fittings are to be removed from the manifold:
1. Mark the fitting orientation for assembly purposes.
2. Remove the fittings from the manifold and discard the O-rings.
3. Lubricate and install new O-rings to the fittings.
4. Align and install the fittings into the manifold and tighten the fittings to the
