1. Replacement Bearing 00-1014-
0007-01 re-places Bearing 00-1014-0007
and Thrust Washer 00-1407-0001.
2. The 00-1014-0007 thrust bearing
used prior to January 1994 has been
discontinued
by the bearing
manufacturer, with no direct replacement
available. Because of the size similarity
of the new bearing’s thrust washers and
the old 00-1407-0001 thrust washer, it is
necessary to discard the old, softer, thrust
washer and use the new, harder, thrust
washer to ensure the softer one does not
become a bearing race.
C.
Inspect all O-rings and replace if cut, cracked,
flattened, or hardened.
D.
A retaining plate, shown in View B of the
assembly drawing, prevents the operating
stem from backing out of the valve if properly
operated. It must be removed to replace the
stem O-ring. When reinstalling this plate,
torque the two hex-head bolts holding it to the
following values:
