Inlet Shut-Off Valves

Figure 5-5. Oil Filter Drain, Vent and Shut-Off Valves

1.If equipped with dual oil filters, open inlet shut-off valve for non-operating oil filter to put it into opera- tion, see Figure 5-5.

2.To isolate oil filter for servicing, close inlet and out- let shut-off valves for the oil filter.

NOTE

To reduce unwanted oil splash from a vent or drain valve, connect a hose to the valve port and direct the gas and oil into a drain pan.

3.Slowly release pressure in the oil filter canister by opening the vent valve. Allow pressures to equalize to atmosphere.

NOTICE

Dispose of the oil in a appropriate manner following all Local, State and Federal ordinances regarding the disposal of used oil.

4.Using an drain pan, open drain valve and allow the oil to completely drain from the oil filter canister.

NOTE

Note orientation of components to aid in installation.

5.Remove bolts and nuts securing cover flange to the oil filter canister. Remove cover flange and spring plate. Retain spring plate.

6.If equipped with a single oil filter element, remove filter element from oil filter canister.

7.If equipped with dual oil filter elements, remove two filter elements and filter element centering piece from oil filter canister. Retain filter element centering piece.

8.Thoroughly clean the oil filter canister, spring plate and centering piece. Inspect spring plate and

centering piece, if damaged, replace as required.

INSTALLATION

NOTE

Ensure oil filter element on the outlet side is fully

seated on the outlet pipe when installed.

9.If equipped with single oil filter element, install oil filter element in canister in orientation noted dur- ing removal.

10.If equipped with dual oil filter elements, install two oil filter elements and centering piece in orientation noted during removal.

11.Position spring plate in orientation noted during removal and install bolts and nuts to secure cover flange to oil filter canister.

12.Tighten nuts, see Appendix A.

13.Using dry nitrogen gas, pressurize oil filter canister through vent valve and check for leaks.

14.Close the vent valve and drain valve.

15.Open outlet shut-off valve for the oil filter that is not in operation.

16.Repeat for second oil filter, as required.
