Fluid-End Parts ListsThe fluid-end parts lists are organized and sequenced according to fluid-endsize. Alternates are given for specific parts that can be used as a substitute if theoriginal part is not available. If a specific part is needed to perform a specific job,those parts are also noted.

Numbers listed in theQuantity (Qty) columns are the totals required to build acomplete fluid-end assembly.

Exploded views of part assemblies are referenced to location (LOC) numbers onthe parts list.

Fluid ends are available with many combinations of curved, straight, andplugged flanges and assemblies with and without spacers. Part numbers of thesecombinations are listed beginning on Page 7-111.

To find information about a particular subassembly more quickly, use the fol-lowing Parts Directory.
