Custom Fire Apparatus, Inc. <br />DRIVELINE, SPICER 1710/1760 SERIES <br />Spicer 1710 series driveline components to be furnished to facilitate pump installation, components shall <br />include: slip stub shafts, slip yokes, and cross and bearings to be compatible with pump end yokes and <br />chassis driveline. Modified drivelines shall be high speed balanced. <br />PNEUMATIC PUMP SHIFT <br />The pump shift is to be pneumatically operated using a standard automotive air valve to control a double <br />action air shift cylinder, designed so that the pump shift remains in its latest position in the event of loss <br />of air pressure. Shift engagement is to be provided by free -sliding shift collar with internal locking <br />mechanism. <br />Pump transmission's pneumatic power shift mechanism and the Pump Shift Console are to be plumbed to <br />the chassis air system, downstream of the vehicle Air Pressure Protection System, using high pressure <br />nylon tubing and brass fittings. <br />SHIFT CONSOLE, COLLAR -LOCK LEVER STYLE <br />Pump Shift Engagement Control will include: air control lever with spring loaded locking collar to <br />prevent it from accidentally being moved from the "ROAD" or "PUMP" position, "PUMP ENGAGED" <br />light indicating mechanical shifting of the pump into the "ROAD" position has been accomplished, "O. <br />K. TO PUMP" light to indicated chassis transmission is in the correct pumping gear, and a control plate <br />describing operation of the pneumatic power shift assembly. <br />An additional indicator light to be furnished on pump control panel, adjacent to, or integral with, engine <br />throttle, to indicate that the vehicle transmission is in the proper gear and driveline is rotating: "O. K. TO <br />PUMP". <br />Pump transmission's pneumatic power shift mechanism and the Pump Shift Console are to be plumbed to <br />the chassis air system, downstream of the Pressure Protection System, using high pressure nylon tubing <br />and brass fittings. <br />The OK to Pump indicator lights, inside the chassis cab and at the pump operator's control panel are to be <br />furnished with circuit protection, wired to and activated by the vehicle transmission position and pump <br />shift signals. <br />TRANSMISSION LOCK -UP <br />The direct gear (1:1 ratio) vehicle transmission lock -up for the fire pump operation is to engage <br />automatically when the pump shift control, in the cab, is activated. <br />LOCATION FOR PUMP SHIFT CONSOLE <br />07/26/22 <br />-78- <br />
