Disassemble Fuel Injection Pump Housing
START BY:a) remove fuel injection pump housing and governorb) remove governorc) remove fuel transfer pumpd) remove fuel injection pumps The disassembly and assembly of all the different combinations of fuel injection pump housings for the 3408 and 3412 Generator Sets are similar so only one will be shown. The minor differences will be shown. Steps 1 and 2 are for fuel injection pump housings that use a Woodward PSG governor.1. Remove wire (1) and cover (2) from the fuel injection pump housing. 2. Remove screw (5), nut (6) and the lock and washer under the nut. Remove cover (4).3. Remove housing (3) from the fuel injection pump housing. 4. Remove shaft (7) from housing (3). 5. Remove bearing (8) from the housing. Steps 6 through 8 are for fuel injection pump housings that use a Woodward PSG governor.6. Remove bolt (9), lever (11) and shaft and lever (10) from the fuel injection pump housing. 7. Put a mark on shaft (13) and lever (10) as to the location of the lever on the shaft. Remove bolt (12). Remove lever (10) from shaft (13). 8. Remove bolts (15) and (16). Move shaft (19) to the right until it is out of the fuel injection pump housing. Remove levers (14) and (20) as the shaft is removed from the fuel injection pump housing.9. Remove the bolts, retainer (17) and gear (18). Step 10 is for fuel injection pump housings that use a Woodward PSG governor.10. Remove ring (21), washer (22) and pinion (24) from the fuel injection pump housing. Remove adapter (23). 11. Remove the adapter over the gear and pinion. Remove gear (25). Hit the end of pinion (26) to remove it from gear (27). Remove pinion (26) and gear (27) from the fuel injection pump housing. 12. Remove bolt (29), bracket assembly (30) and link (28). 13. Pull the end of spring (33) out away from bracket (34). Remove pin (31), lever (32) and spring (33) from bracket (34). 14. Remove two racks (36) from the fuel injection pump housing. Step 15 is for fuel injection pump housings that use a Woodward PSG governor.15. Remove plug (35). Remove the O-ring seal on the plug. Fuel Injection pump housings that use a dashpot type governor will have valve (37) and not plug (35).16. Remove valve (37) from the fuel injection pump housing. 17. Remove two O-ring seals (41) from valve (37). Push in on piston (39). Remove pin (38). Remove piston (39) and spring (40) from valve (37). 18. Put identification on each lifter as to its location in the fuel injection pump housing. Remove lifters (42) from the fuel injection pump housing.19. Remove camshaft (43). 20. Use tooling (A) to remove dowel (44) and shaft (46). Use tooling (B) to remove two bearings (47) and two bearings (48) from the fuel injection pump housing. Remove pin (45). 21. Use tooling (C) to remove rack bearings (48) from the fuel injection pump housing. 22. Use
