Remove & Install Fuel Injection Pump Housing & Governor
Start By:a. remove fuel injection linesb. remove air inlet manifold Step 1 is for marine engines only.1. Remove four bolts (1) and pulley guard (2). 2. Remove the plug from the cover and install tool (A). Turn the crankshaft (clockwise) until the timing pin drops into the groove (slot) in the fuel injection pump camshaft. 3. Remove two nuts (4) and tachometer drive cover (3). 4. Remove tachometer drive shaft (5).
Old 5P2371 Puller Plate shown for location purposes only.5. Install tooling (B) into the camshaft drive gear for the fuel injection pump. Turn the center bolt of tooling (B) until the drive gear is free of the shaft. Remove tooling (B). 6. Remove the plug from the timing hole in the front cover and install a 5/16"-18 NC bolt (6) 2 1/2 in. long. The cover bolt from hole (7) can be used. Turn the crankshaft (clockwise) until bolt (6) can be installed into the timing gear and is in the center of the timing hole. The camshaft for the fuel injection pump is now in correct time to the engine. 7. Remove lines (8) and bolts (9).8. Remove the fuel injection pump housing and governor as a unit. The following steps are for installation of the fuel injection pump housing and governor.9. Put the fuel injection pump housing and governor in position on the engine.10. Install bolts (9) and lines (8).
Earlier tachometer drive shaft
Later tachometer drive shaft Illustration A23394P1 shows earlier tachometer drive shaft that must be tightened to a torque of 110 7 N m (80 5 lb ft). Illustration A23857P1 shows a later tachometer drive shaft. When the engine is equipped with the later tachometer drive shaft, tighten it to a torque of 149 14 N m (110 10 lb ft).11. Install tachometer drive shaft (5) and tighten it to a torque of 110 7 N m (80 5 lb ft).12. To check the timing, remove the timing pin [tool (A)] and bolt (6). Turn the crankshaft (clockwise) two revolutions and install the timing pin [tool (A)] and bolt (6) back in place. If the timing pin or bolt can not be installed, the fuel injection pump camshaft must be put in time again before doing Step 13.13. Remove bolt (6) from the timing gear. Install the plug into the timing hole.14. Remove tool (A) from the timing groove (slot) in the fuel injection pump camshaft and install the plug.15. Install tachometer drive housing (3) and nuts (4). Step 16 is for marine engines only.16. Install pulley guard (2) and bolts (1).End By:a. install air inlet manifoldb. install fuel injection linesSeparate Fuel Injection Pump Housing & Governor (Serial Numbers 90N1-90N6120)
Start By:a. remove fuel injection pump housing & governor 1. Install the fuel injection pump housing on tool (A).2. Remove bolts (1) and governor housing (2). 3. Remove two springs (4) and seat (5).4. Remove seat (7) and spring (6).5. Remove cover
