 -back-up rings (36), (37), (39), (40) and
 -O-rings (35), (38).

 (e)
 Put the bobbins (9),(30) into plastic bags to keep them clean.

 (f)
 Remove the check valve 3093GM and discard the O-ring (23).

 (g)
 Remove the check valve 3094GM as follows:

 (h)
 Remove the coupling half (46) and discard the packing (47).

 (i)
 If necessary, remove the reducer (5) and discard the packing (52).

 (j)

 (k)
 Install the blanking plugs on the open ports of the manifold (7).

 (l)
 Install the blanking plugs on all of the removed components.

 (2)
 Install the removed components on the replacement manifold (7) as follows:

 (a)
 Remove the blanking plugs from the manifold (7) and the components.

 (b)
 Lubricate the new O-rings and the threads of the components with HYDRAULIC FLUIDS (Material No. 02-003).

 (c)
