1 Use tool group (A) to install the bearings in bracket assemblies (1) until they are in the center of their bores. Check the bore in the bearings after assembly. The bearing bores must be 21.925 ± 0.015 mm (.8632 ± .0006 in.).

2. Install two bracket assemblies (1) on each side of the 3512 Engines. Install one bracket assembly (1) on the 3508 Engines.

3. Install control shaft (2) on each side of the engine block.

4. Use tool group (A) and install the bearings in the center of the bores in supports (3). Check the bore in the bearings after assembly. The bearing bores must be 21.925 ± 0.015 mm (.8632 ± .0006 in.).

5. Install supports (3) to hold the front of the control shafts. Install levers (4) on each of the control shafts.

6. Connect lever assembly (6) to rod assembly (5).

7. Install lever assembly (6) and rod assembly (5) as a unit in each cylinder head. If necessary, use tool (B) to turn the engine flywheel until the camshaft moves enough to permit the lever of the rod assembly to move into position.

8. Make sure lever assembly (6) is engaged correctly with the fuel injection pump rack and install the two bolts to hold it in place.

9. Make sure the lever for the fuel control and assembly is in position on the control shaft and install the bolt and cap (7).

10. Install access covers (8) and seal over the camshafts and control rods.

11. Use tool group (A) and install the bearings in the center of the bores in front control shaft brackets (9). Check the bore in the bearings after assembly. The bearing bores must be 21.925 + 0.015 mm (.8632 ± .0006 in.). If necessary, make a replacement of the pins in brackets (12). The pins must extend 8.0 + 0.5 mm (.315 ± .020 in.) above the surface of brackets (9).

12. Install brackets (9) and levers (10) on the ends of front control shaft (11).

13. Put shaft (11) in position on the front of the engine. Make sure levers (10) and (4) are engaged correctly and install the bolts to hold the brackets and shaft (11 ) to the engine.

NOTE: After assembly the control shafts must turn freely by hand and the linkage must return to the "SHUTOFF" position when it is turned and released. See TESTING AND ADJUSTING section for the correct adjustment of the fuel injection control group.

start by: a) remove rocker shafts and push rods

1. Drain the coolant from the cooling system.

2. Shut off the fuel supply to the engine.

3. Remove fuel lines (2) from the cylinder head and fuel line manifold (1). Remove the bolts and remove fuel line manifold (1) and the bracket from the cylinder head.

4. Remove the access cover from over the camshaft and remove bolt (4) and cap (5) that hold fuel rod assembly (3) to the fuel control shaft.

5. Remove bolts (7) and remove lever assembly " (6) and fuel rod assembly (3) as a unit. If necessary remove the cover from the front right side of the flywheel housing and use tool (A) to turn the engine flywheel until the camshaft is moved in a position so the lever of rod assembly (3) can be removed between the engine block and camshaft.

6. Remove the bolts and remove valve cover base (10) and the gasket from the cylinder head.

7. Remove bolt (8) and clamp (11) from the fuel injector.

NOTICE Do not put a force on the fuel injection rack or cause damage to it when the injectors are removed.

8. Use a pry bar to loosen fuel injector (9) and remove the injector from the cylinder head.
