Section 1: Purge Air from Secondary Divider Valve Lube-to-Lube Point Lines
Refer to F
. 7 when following this procedure
1. Install the line from the secondary divider valve to
the lube point, but do not completely tighten the
connection at the lube point.
2. Remove the performance indicator port plug or the
performance indicator from the working valve
section on the secondary divider valve assembly
corresponding to the outlet port and the line
connected to the lube point.
3. Attach a hand pump filled with clean, filtered
lubricant to the port on the secondary divider valve
that was opened in step 2.
4. Operate the hand pump until air-free lubricant is
observed flowing from the line at the lubrication
point.
5. Tighten the fitting at the lubrication point while the
lubricant is still flowing.
6. Remove the hand pump and reinstall the
performance indicator or indicator port plug
removed in step 2.
NOTE:
If check valves were not installed at the
lubrication point, lubricant may continually drain out of
the line when the secondary port is open. When check
valves are not used, the method for bleeding this line is
to tighten the line at both ends and repeatedly cycle the
secondary divider valve by hand pump operation until
air-free lubricant flows from the lubrication point
