6.Install manual pump into each indicator port of sec- ondary divider valve in turn and slowly operate pump (FIG. 14). 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

Table 4: Torque Values (*see FIG. 2, page 4)

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 (FIG. 15). Also remove end plugs only and try to move each piston back and forth without removing the piston from the valve sec- tion.

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.

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 4 (below).
