1989 Dodge 5.9L Cummins Fuel Injection Pump Installation & Torque Specs

This document is page 2 of a service procedure for the 5.9L 6-cylinder Cummins B Series turbo diesel engine (VIN code 8) in a 1989 Dodge Pickup, printed December 15, 2003 from a 2001 MRIC/Snap-on Tools information system. It covers installation of the fuel injection pump, both the original pump and a new or rebuilt pump. It includes Fig. 13, a labeled diagram (courtesy of Chrysler Motors) showing the gear housing, timing marks, lock bolt, fuel injection pump flange, and special washer. Key steps include: ensuring gasket surfaces are clean, setting the engine at TDC using the timing pin, installing a new gasket and the key in the pump shaft, installing mounting nuts loosely so the pump can rotate in its slots, tightening the drive gear retaining nut to 11-15 ft. lbs. (15-20 N.m), aligning timing marks, tightening mounting nuts to 18 ft. lbs. (24 N.m), installing the special washer under the lock bolt and tightening it to 10 ft. lbs. (14 N.m), then bleeding the fuel lines. Repeated cautions warn against letting the key drop from the pump shaft during removal or installation. Cross-references are given to FUEL INJECTION PUMP TIMING under ADJUSTMENTS and to FUEL LINE BLEEDING.
