CENTERING PIN.
The pin must be removed daily for
sanitation. The vent slot should be clean,
and free of obstruction. The small diameter
that the bushing runs on is the only place
that wears. Some discoloration is
permissible, but if this area turns blue, it is
possible that the machine was run empty
for an extended period of time. The
damage from empty running cannot be
repaired, and the pin should be replaced.
Under normal conditions the pin usually
lasts about three months, or three bushings.
If some roughness is noticed this can be
smoothed out with an external grinder, or
very fine sand paper in a lathe. A rough
surface on the pin will wear the bushings
out at an unexceptable rate.
The pin should be replaced when the
diameter has .030 wear, or it measures
1.470 .

SPRINGS.
The washer springs last a very long time.
They are designed to last for about five
million cycles, so it is doubtfull they will ever
wear out. When placed together as shown,
the gap at the outside should measure 3/16".
