Assembling the Manifold Valve
1. Check the condition of the outlet fitting O-rings
(section valve manifold only), end cap O-rings, back
seating O-rings, and ball seat for damage or wear
(
Figure 118 and Figure 119 ).
Note:
Replace any damaged or worn O-rings or seats.
2. Apply grease to the valve stem and insert it into the
valve-stem seat (
Figure 118 and Figure 119 ).
3. Install the valve stem and seat into the manifold and
secure the stem and seat with the stem retainer (
Figure
118 and Figure 119 ).
4. Ensure that the back seating O-ring and the ball seat
are aligned and seated into the end-cap fitting (
Figure
118 and Figure 119 ).
5. Install the end-cap-fitting assembly onto the manifold
body until the flange of the end-cap fitting touches the
manifold body (
Figure 118 and Figure 119 ), then turn
the end-cap fitting an additional 1/8 to 1/4 turn.
Note:
Use caution to prevent damage to the end of
the fitting.
6. Insert the ball into the valve body ( Figure 120 ).
Note:
The valve stem should fit inside the ball-drive
slot. If the valve stem does not fit, adjust the position
of the ball (
Figure 120 ).

7. Turn the valve-stem assembly so that the valve is closed
(
Figure 117 ).
8. Repeat steps 4 and 5 for the other end-cap-fitting
assembly.
Installing the Agitation-Manifold Valve
1. Align the flange of the agitation bypass valve, 1 gasket,
and the end-cap-fitting flange of the agitation-valve
manifold (
Figure 121 ).
Note:
If needed, loosen the mounting hardware for
the pressure-filter head as needed to provide clearance.

2. Assemble the agitation bypass valve, gasket, and
agitation-valve manifold with a clamp, and tighten by
hand (
Figure 121 ).
3. Align a gasket between the flanges of the pressure-filter
head and the agitation-valve manifold (
Figure 121 ).
4. Assemble the pressure-filter head, gasket, and
agitation-valve manifold with a clamp, and tighten by
hand (
Figure 121 ).
5. Align a gasket between the flanges of the agitation-valve
manifold and the reducer coupling (
Figure 121 ).
6. Assemble the agitation-valve manifold, gasket, and
reducer coupling with a clamp, and tighten by hand
(
Figure 121 ).
7. Align a gasket between the flanges of the agitation-valve
manifold and the adapter fitting for the agitation
throttle valve (
Figure 121 ).
8. Assemble the agitation-valve manifold, gasket, and
adapter fitting with a clamp, and tighten by hand
(
Figure 121 ).
9. If you loosened the mounting hardware for the
pressure-filter head, tighten the nut and bolt to 1978 to
2542 N∙cm (175 to 225 in-lb).
