- 4) Remove and discard the hose connected between the supply air tube and 144-0526 Pressure Regulator.
- 5) Remove the pressure regulators from the OMD support bracket (dispose of the larger pressure regulator but keep the smaller 144-0526 Pressure Regulator for reuse). Inspect 144-0526 Pressure Regulator for corrosion and replace as needed.
- 6) Remove the oil collection box. The oil collection box will not be reused.
- 7) Remove bolts supporting the manifolds.
- 8) Loosen the 192-1405 Nut on each of the suction tubes and carefully remove both manifolds. The 192-1406 Ferrules will not be able to be removed and will not be reused along with the nut and manifolds.

- 10) Carefully loosen the connections between the suction funnels and the block. Rotate each as shown in Image1.6.1 with the opening of the suction funnel at either the 4 O'clock position or the 8 O'clock position. The suction funnel openings will be pointed away from the main bearing webs. Tighten to 35+/-5 N.m.
