Reassembling the Strainer

( See Page 7 For Item Numbers)

1. Place the strainer basket into the housing.

2. Place the end cover O-Ring (4) in the groove in the

end cover (2).

3. Place the end cover (2) with the O-Ring installed, on

the strainer housing end (1).

4. Fasten the end cover with the 4 washers (8) and

screws (7). Evenly tighten all screws.

Tightening Screws and Nuts

Leakage that occurs after tightening the fasteners
indicates a damaged seal or distortion to the surface of
the cover. In either of these cases, the seals or cover
must be replaced. Excessive tightening will not stop the
leakage. See chart below for proper torque standards.

*Torque specifications are ±10%.
