Beginning at serial number 031513001, the valve handle assembly has changed. The prior style (part # 17279) used
a steel spool sleeve installed in the valve handle assembly. The new style valve handle assembly (part # 73167) does
not use a spool sleeve.
New style valve spool assembly (part # 73046) is required for use in the new style valve handle assembly.
The new style valve handle assembly will only accept new style on/o spool (PN 73046). If replacing old style 17279
valve handle assembly with new style 73167, replacement of 73046 valve spool is also required. New style on/o spool
73046 will t old style and new style valve handle assemblies. Old style valve spool P/N 07998 is no longer available
and substitutes to new style 73046.
Please refer to the photos below of the old style and new style valve handle and on/o spools.
