The unit's components did not change when the nomenclature did (a few engineering changes have taken place since this RPL was last issued, and the part number changes are noted). The complete model number nomenclature currently used has been added to this revision. Unless otherwise noted, all components listed in this revision apply to both the current and the original model numbered units. WSHP; CCW Vint. E; WCDE,WCDD,WCMG Sizes Des. 1&2 Rev.
