893307A01 Mariner TUBE OUTLET ASSEMBLY

1. Remove plug (1) from the fuel injection pump housing.2. Use tool (D) to loosen nut (2) for the fuel injection pump to be removed. Disconnect the fuel injection line nuts, and remove the felt washer. 3. Install tool (A) in the fuel pump housing as shown with the square end down. Use a small amount of hand force to push down on tool (A) while the control lever is moved forward to the "FUEL ON" position. Rack travel will stop in the center (zero) position. Hold a light forward force on the governor control lever to keep the fuel racks in the center (zero) position.4. Use tool (B) to remove bushing (3) from the fuel injection pump housing. 5. Remove bushing (3) and O-ring seal (4). 6. Use tool (C) to remove fuel injection pump (5).
When injection pumps, spacers and lifters are removed from the injection pump housing, keep the parts of each pump together so they can be installed in their original location.
7. Remove spacer (6) from the fuel injection pump housing. Make a note of the position from which each spacer was removed so each spacer can be installed in its original position.
Be careful when the fuel injection pumps are disassembled. Do not damage the surfaces of the plungers, barrels and bonnets. Any scratches will cause leakage inside the fuel injection pump. The plunger and barrel for each pump are made as a set. Do not put the plunger of one pump in the barrel of another pump. The check assemblies are made as a set. Do not mix the parts of the different check assemblies. Do not remove or make any adjustments of the gear segment on the plunger. It has been present at the factory. If one part has wear, install a complete new pump assembly. Be careful when the plunger is put into the bore of the barrel.
8. Disassemble the fuel injection pump as follows: Remove ring (7). Make a separation of bonnet (10) from barrel (9). Remove the spring and the check assembly from the bonnet. Remove plunger (8), the washer and spring from barrel (9).Install Fuel Injection Pumps
1. Inspect all parts for wear or damage. The plunger and barrel are serviced only as an assembly. 2. Put clean diesel fuel on plunger (1), and put plunger (1), washer (6) and spring (2) in position on barrel (3).3. Put check valve assembly (7) and spring (8) in bonnet (9). Connect bonnet (9) and barrel (3) together with ring (4). 4. Put spacer (10) into position in the pump housing bore. Be sure the correct spacer is with each pump. 5. Note the location of dowels (11) and (12) in the fuel injection pump housing. These dowels are for alignment of the fuel injection pump. 6. Slot (13) in gear segment (5) must align with dowel (11).7. Groove (14) must engage with dowel (12). 8. Use tool (A) to put the fuel racks in the center (zero) position. See topic Remove Fuel Injection Pumps.9. Use tool (C) to install the fuel injection pump. 10. Install a new O-ring seal (15) and bushing (16) in the fuel injection pump housing bore. If the pump is in the correct position, bushing (16) can be installed with fingers until it is even with the outside surface of the housing. If the bushing cannot be installed as described, remove the fuel injection pump, and repeat Steps 4 through 6. Use tool (B) to tighten bushing (16) to a torque of 205 14 N m (154 10 lb.ft.).11. Install the felt washer in the fuel injection pump housing. 12. Connect the fuel injection line to the fuel injection pump. Use tool (D) to tighten the fuel injection line nuts to a torque of 41 7 N m (30 5 lb.ft.).13. Check the correct installation of the fuel injection pumps with the engine stopped. See the topic Fuel Rack Travel.
If one or more of the injection pumps have been installed wrong, damage to the engine is possible if cautions are not taken when the engine is first started. Make preparation to close off the air intake to stop the engine if necessary.
