Remove Fuel Injection Control Linkage
Start By:a. remove rocker shaft assemblies and push rodsb. remove front drive housing 1. Remove the bolts that hold the brackets for shaft (3) to the front of the cylinder block. Disconnect the levers on shaft (3) from the levers on shafts (1) and (2), and remove shaft (3) from the engine. 2. Remove levers (5) and (6) and brackets (4) from shaft (3). 3. Remove bearings (7) from brackets (4) with tooling (A). 4. Remove access covers (8). 5. Remove the bolts and caps (10) that hold the levers of rod assemblies (9) to fuel control shafts (1) and (2).6. If necessary, remove the cover from the front right side of the flywheel housing, and use tool (B) to turn the engine flywheel until the camshaft is moved in a position so the levers of rod assemblies (9) can be removed between the cylinder block and camshaft. 7. Remove bolts (12), and remove lever assemblies (11) and fuel control rod assemblies (9) as a unit from each cylinder head assembly. See Step 6 if the levers on the lower ends of rod assemblies (9) do not have enough clearance to be removed from the engine. 8. Remove locknut (13), the washer, and rod assembly (9) from lever assembly (11). 9. Remove levers (15) from control shafts (1) and (2).10. Remove the rings and washers that hold the control shafts in place in supports (14).11. Remove the bolts and supports (14) from each side of the engine.12. Remove the washer and ring from the control shafts. 13. If necessary, remove bearings (16) from supports (14) with tooling (A). 14. Pull control shafts (1) and (2) out of bracket assemblies (17). Remove the control shafts from the engine.15. Remove the bolts and two bracket assemblies (17) from each side of the engine. 16. If necessary, remove bearings (18) from bracket assemblies (17) with tooling (A).Install Fuel Injection Control Linkage
1. Use tooling (A) to install the bearings in brackets (17) until they are centered in the brackets. Check the bore in the bearings after assembly. The bearing bores must be 21.925 0.015 mm (.8632 .0006 in) after installation. 2. Install two bracket assemblies (17) on each side of the engine. The control shafts must be installed with the two grooves in the end of the control shafts toward the front of the engine.3. Install control shafts (1) and (2) in bracket assemblies (17). 4. Use tooling (A), and install the bearings in the center of bores in supports (14). Check the bore in the bearings after assembly. The bearing bores must be 21.925 0.015 mm (.8632 .0006 in). 5. Install the ring and washer on the control shafts.6. Put supports (14) in position on the control shafts, and install the bolts that hold them.7. Install the other washer and ring to hold the control shafts in place.8. Install levers (15) on each of the control shafts. 9. Connect lever assembly (11) to
