If the lubricant does not freely discharge through
the open indicator ports of the second divider
valve, the blockage is in this divider valve or the
supply line. Disconnect the supply line at the
secondary inlet fitting and slowly operate
manual pump to verify the blockage location. If
the blockage is in this divider valve, go to step 7.
6. Install the manual pump into each indicator port of
the secondary divider valve, in turn, and slowly
operate the pump (F
. 14). If high pressure exists,
the blockage has been located. Look for crushed
lines, tight bearings, and improperly drilled fittings
and lube inlet ports.
Correct as necessary.
7. Clean Divider Valve.
NOTE:
Dirt and foreign material damage lubricating
equipment. Perform all service and disassembly under
the cleanest possible conditions.
NOTE:
Take notes during the process to aid in
reassembly.
a. Before disassembling any divider valve, make a
sketch noting the arrangement of the Valve
Sections. For example: INLET 10T - 20S - 10T -
30S - END (F
. 15). Only remove the end plugs.
Try to move each piston back and forth without
removing the piston from the valve section.
b. If all the pistons move freely and there is no
indication of a more serious problem, replace
the end plugs.
c. Using a new gasket, tighten and torque as
indicated in the table.

NOTICE
Do not insert hard metal objects into piston bore (i.e.,
punches, screwdrivers, etc.). Hard metal objects can
damage the surface and cause divider valves to leak
fluid. Use a brass rod and hand pressure only.
