Att 1 - CPK-5 Specifications.pdf

This document is a technical specification for a replacement CPK-5 two-stage fire pump (Serial #156883) designed to replace an existing unit (Serial #156882) on a 2016 Oshkosh fire truck. The pump must be manufactured to exact specifications including Model CPK-5 with a rated capacity of 320, iron material construction, and red oxide primer paint per specification M 4142-P (PR1532). The pump requires a 1-1/2 inch SAE-10 spline input shaft, 12-volt operation, 1350 discharge pressure, clockwise input rotation, upward pump discharge position, 2025 hydro test pressure, and a 2.26 transmission ratio with inverted transmission mounting position.

The specification details required components including CP-5 Series Pump assemblies (83421-1A iron body with 4-inch Victaulic intake and 1-1/2 inch ANSI discharge, and 83422-1A shaft and impeller assembly), a K Series Transmission system (83423-2C inverted case mounting with 1.500-10 SAE splined input shaft, 83423-1A heavy duty transmission, V2861 end yoke, lubricant and breather tags), product manual with two thumb drives (F2743), serial plates (52906 panel and 52905), and a one-year conditional parts warranty. All components must be configured for clockwise input rotation with discharge positioned upward and inverted transmission mounting to ensure complete compatibility with the original pump being replaced.
