An orifice is placed beneath the hydraulic fittings in the control
manifold LS (OR1), C3 (OR3), C2 (OR5) and C5 (OR7) ports. If any
of these fittings are removed from manifold, make sure to remove
the orifice, note its orientation and label its position for assembly
purposes.
9. If hydraulic fittings are to be removed from manifold, mark fitting orientation to
allow correct assembly. Remove fittings from manifold and discard O−rings.

on fittings.
When installing the orifice in manifold port C3 (OR3), C2 (OR5)
and C5 (OR7), make sure that orifice is in the correct port,
oriented correctly and flat in the base of the port cavity. Manifold
damage is possible if the orifice is cocked in the cavity.
