2. Remove spring (4) and check assembly (5) from the bonnet. 3. Remove plunger (8) and washer (7) as a unit from spring (6) and the barrel. Remove washer (7) from the plunger. Remove spring (6) from the barrel.
Do not remove the gear from the plunger. The gear and plunger are assembled and adjusted at the factory.
Assemble Fuel Injection Pumps
Put clean fuel oil on all parts during assembly.
1. Install spring (2) on barrel (1). Install washer (3) on plunger (4) with the flat side toward the gear. Install plunger (4) in barrel (1) and engage washer (3) in spring(2). 2. Install spring (5) and check assembly (6) in bonnet (7).
Do not slide bonnet (7) across the face of barrel (1) when ring (8) is installed. The check assembly in the bonnet can put scratches in the face of barrel (1).
3. Put bonnet (7) in position on barrel (1) and install ring (8) to hold the bonnet and barrel together.ENDBY:a) install fuel injection pumpsDisassemble Fuel Injection Pump Housing
START BY:a) remove fuel injection pumps 1. Remove elbow and plate (1) (orifice) under the elbow. 2. Remove fuel rack (2) from the fuel injection pump housing. Spacers (3) are different thickness and are used to make a setting of the injection timing between cylinders. Spacers (3) and lifters (4) must be installed in the same bore in the pump housing from which they are removed. Put identification on the spacers and lifters as to their location in the pump housing. 3. Remove spacers (3) from the pump housing. 4. Remove lifters (4) from the pump housing. 5. Remove bolt (5) and lock and plate (6) from the camshaft. 6. Remove spring (7) and gear (8) from the camshaft. 7. Carefully remove camshaft (9) from the pump housing. Turn the camshaft during removal. 8. Remove fuel rack bearing (10) from the pump housing. 9. Remove fuel rack bearing (11) from the pump housing.10. Use tooling (A) as shown to remove the bearings for the camshaft from the pump housing.Assemble Fuel Injection Pump Housing
Be sure all oil passages in the pump housing are clear. Put clean oil on all parts before assembly. 1. Install the camshaft bearings in the fuel injection pump housing with tooling (A). Install the bearing in the governor end of the housing so the lubrication hole in the bearing is in alignment with the lubrication hole in the housing. Install the camshaft bearings so they are 0.25 0.13 mm (.010 .005 in.) below the ends of the pump housing. After
