Section 2: Purging Air from Master to Secondary Divider Valve Lube Lines

Steps 1- 9, refer to FIG. 7.

1. Install the lines from the master divider valve to the sec-

ondary divider valve, but do not completely tighten the

connection at the secondary divider valve’s inlet.

2. Remove the performance indicator port plug or the

performance indicator from the working valve section on

the master divider valve assembly corresponding to the

outlet port and the line connected to the secondary valve.

3. Attach a hand pump filled with clean, filtered lubricant on

the master divider valve that was opened in Step 2.

4. Operate the hand pump until air-free lubricant is observed

flowing freely from the secondary valve’s lube inlet

connector.

5. Tighten the fitting at the secondary valve’s inlet while

lubricant is still flowing.

6. Remove all of the indicators or indicator port plugs from

the secondary divider valve’s working sections.

7. Operate the hand pump again until air-free lubricant is

observed flowing out of all the secondary divider valve’s

indicator ports.

8. Reinstall all of the performance indicators or port plugs in

the secondary divider valve while lubricant is still flowing

from the ports.

9. Remove the hand pump and reinstall the performance

indicator or indicator plug removed in Step 2 into the

master divider working valve’s open port.

The system is now ready for operation.
