Note: The lift arm and bucket control spools are each
equipped with a unique load check spool. The load
check spools provide bucket positioning (self-Leveling).
The components can be seen above in figure 16-20.
The load check spools are similar, but they are not
identical. The main spools are also unique. All
spools must be reinstalled as found upon disas-
sembly to function properly.

Note: There is a passageway in the load check spool
that must be kept clear to ensure proper operation. It
leads from the small hole in the side of the spool to the
end of the spool. If you cannot blow air through this
passageway, it must either be cleaned or the load
check spool must be replaced to restore proper func-
tion. (fig. 16-24)
