  3  Carefully lift the valve housing straight up.  The balance ring should
lift away with the valve housing.  The valve will remain on the valve
plate.

machined surfaces.  Remove the 108 mm [4.25 in.] seal and 9,5 mm
[.375 in.] o-ring.

drain plug and o-ring from the bottom of the valve housing (see Figure 3).

balance ring fits into the valve housing tightly. A sliding hammer
bearing puller may be needed to loosen it.
