9. Insert both pistons (14 and 11) into the bottom of cylinder. Use retaining ring pliers to install
the pistons with the guide pin in the hole of the valve body (8). Refer to Figure 7-5.
10.Apply KRYTOX 240 AC grease to the compression plate (17) beveled cone. Insert the ball
(20) into the greased cone.
11.Insert both the compression plate (17) and ball (20) into retaining base (18). Refer to figure
7-6.
12.Apply KRYTOX 240 AC grease to base socket head set screw (21) then screw it into
retaining base (18). Leave about one thread of set screw showing.
13.Place compression spring (16) on compression plate (17).
14.Place compensation plate (15) over the compression spring (16).
15.Before final assembly of components, apply a thin film of KRYTOX 240 AC grease to the
outside of compensation plate (15) and inside of retaining base (18).
16.Place the compression spring (16), compression plate (17); socket head set screw (21),
retaining base (18) and compensation plate (15) into the valve body (8).
17.Use the retaining ring pliers supplied with the repair kit to reinstall the retaining ring (19).
18.Prepare to install the manifold (23) by cleaning the flat surface on the side of the valve body
(8) and then installing the three small O-rings (22) into the manifold (23).
19.Align and install manifold (23) onto valve body (26) with two 8-32 screws (24 and 25). The
shorter screw is installed in the top. Attach the manifold so that inlet holes on the manifold
align with inlet holes on the valve body. Refer to Figure 7-4.
When installing the manifold be careful not to damage the air tubes. If the tubes are bent
too close to the manifold, it is possible to break them.
