Inspection (Fig. 16)
Inspect all parts of the filter assembly before reassembly.
1. Inspect the ball inside the filter element. If the ball has
pressure cuts or scratches, replace the filter element.
a.
If the ball is cut, remove the PTFE o-ring (5) using an o-ring pick
and remove the carbide seat (6).
b.
Check the seat for nicks or grooves. If the seat is damaged,
replace.
i
Removal of the PTFE o-ring will damage the o-ring
and require replacement.
2. Remove the spring (2) from the spring guide on the filter cap.
a.
Measure the length of the spring uncompressed. If it measures
less than 3/4" from end to end, replace.
b.
Push the spring back onto the spring guide until it "snaps" back
into position.
3. Inspect the two PTFE gaskets (7,8) and the PTFE o-ring (5) for
deformity, nicks, or cuts. Replace, if needed.
i
The PTFE gaskets, PTFE o-ring, and spring are
packaged in Filter Service Kit P/N 930-050.
Reassembly (Fig. 16)
After cleaning and inspecting all parts, reassemble the filter.
1. Place the carbide seat (6) into the filter body (4). Make sure
the beveled side of the seat is facing up.
2. Place the PTFE o-ring (5) into the groove on the outer
diameter of the carbide seat (6).
3. Place the filter element with ball (3) into the filter body (4).
i
The top and bottom of the filter element with ball
are identical.
4. Push the spring (2) back onto the spring guide of the filter cap
(1) until it "snaps" back into position, if not already done.
5. Place the thin PTFE gasket (8) onto the step at the top of the
filter body (4).
6. Place the thick PTFE gasket (7) onto the top of the thin gasket
(8).
7. Tighten the filter cap assembly (1) onto the filter body (4).
