fitting and slowly operate manual pump to verify
location. If blockage is in this divider valve, go to
step 7.
6. Install manual pump into each indicator port of sec-
ondary divider valve in turn and slowly operate
pump (F
IG. 13). If high pressure exists, blockage
has been located. Look for crushed line, tight
bearing, improperly drilled fittings and/or lube
inlet port. Correct as necessary.
7. Clean Divider Valve
NOTE: Dirt and foreign material will damage lubricating
equipment. Perform all service and disassembly under
the cleanest possible conditions.
a. Before disassembling any divider valve, make a
sketch noting the arrangement of Valve Sec-
tions. For example: INLET 10T - 20S - 10T -
30S - END (F
IG. 14). Also remove end plugs
only and try to move each piston back and forth
without removing the piston from the valve sec-
tion.
b. If all pistons move freely and there is no indica-
tion of a more serious problem, replace end
plugs.
c. Using a new gasket, tighten and torque as indi-
cated in Table 1 (page 11).
