disassembly. With the individual sections on the bench, remove the end plug from both ends of
the section.
Taking one section at a time remove the piston, if it appears to be jammed, try removing it from
the other direction. With badly jammed pistons it may be necessary to use a brass rod and lightly
tap piston out.
Clean sections and pistons in a suitable clean solvent until all lubricant has been removed. Use
compressed air to dry and blow out all ports thoroughly. Ensure all passages are clean and open
by inserting a small wire probe into each passageway. Inspect the cylinder bore and piston
carefully for scratches, score marks or other damage.
Note: If either piston or cylinder bore is damaged, a new section must be installed. All pistons
are selectively fitted to the bore for proper clearance. Care must be taken to install piston only
into the divider valve section from which it was removed.
If divider valve section and piston both appear in good condition, reassemble section making
certain that piston moves smoothly but snugly in cylinder bore. Repeat cleaning and inspection of
each section. After all sections have been cleaned, blown out, inspected and found to be in good
condition, reassemble divider valve as indicated by the notes and sketches.
Caution: Use all new gaskets, and tighten divider valve sections to correct torque values.
Test operation of divider valve using manual pump.
Other Blockage
Contamination
If dirt, foreign material or any other form of contamination is found in a divider valve, cleaning that
divider valve will only temporarily solve contamination blockage problems. If contamination is
an issue, the source of the contamination must be determined and eliminated for
satisfactory lubrication system operation.
Potential sources of contamination can be the reservoir filling method, dirty or missing lubricant
filters, or the lubricant itself. The method of filling the reservoir should be reviewed to eliminate
any chance of foreign material being introduced during the filling operation. Lubricant filters
should be inspected to determine if the filter elements are clogged or missing, and corrective
action taken. Some grease lubricants contain high concentrations of lubricating solids, and are
not suitable for use in an automatic lubrication system.
Lubricant Separation
Some lubricating greases will separate under the operating pressures in an automatic lubrication
system. When separation occurs, a hard wax or soap-like material is found in the divider valve
sections. Separation is a result of oil in the lubricant being squeezed from the thickener of the
grease. The deposits in the divider valve are the thickening component of the lubricant. If
separation is occurring, cleaning the divider valve will usually only temporarily solve the problem,
and an alternative lubricant should be recommended..
Consult your lubricant supplier for recommendations on alternate lubricants and your local Lincoln
Distributor to verify compatibility with progressive lubricating systems.
