Start By:a. remove rocker shaft assemblies and push rodsb. remove tachometer drivec. remove governor 1. Remove access covers (1) from the sides of the engine. 2. Remove bolts (3) and caps (4) that hold fuel rods (2) to the fuel control shaft. 3. Remove bolts (5) to remove lever assembly (6) and fuel rod assembly (2) as a unit from the cylinder heads. If necessary, use tool (A) to turn the flywheel until the camshaft is moved in a position so that the fuel rod assembly can be removed between the engine block and camshaft. 4. Remove the cover over the camshaft drive gear (Right side only).5. Remove the bolt and plate (7) that fastens gear (8) to the camshaft. 6. Put the three washers from tooling (B) behind plate (7) and install the bolt and plate (7).
Do not apply more than 51675 kPa (7500 psi) pressure to 1P820 Hydraulic Puller. 8B7559 Adapters are rated at 6 1/2 ton each and 1P820 Hydraulic Puller is rated at 17 ton at 68,900 kPa (10000 psi). If to much pressure is applied, the gear may be damaged. Personal injury can also be the result.
7. Install tooling (B) on camshaft drive gear (8). Apply 51,675 kPa (7500 psi) to the puller and hit the screw part of the puller with a hammer until the gear is free of the camshaft taper. Remove tooling (B) and gears (8). 8. Remove bolts (9) and thrust washers (10) that fasten camshaft in the engine block. 9. Push the valve lifters up away from the camshaft into the cylinder head assemblies, and hold the lifters in position. O-ring seals (11) can be used to hold the valve lifters up. 10. Remove the bolts and cover (12) from the front of the engine.
Typical Example11. Install tooling (C) on each end of camshaft (13). Tooling (D) can be installed on the flywheel housing to remove the camshafts from the rear of the engine, or it can be installed on the front drive housing to remove the camshafts from the front of the engine.12. Install tool (D) on the flywheel housing as shown.13. Install tool (E) on one end of tooling (C).14. Pull the camshaft out while rotating it with tool (E). Pull the camshaft out of the engine until a hoist can be fastened to it. Remove camshaft (13) from the engine. The weight of the camshaft is 75 kg (165 lb). 15. Remove bolts (14). Separate the camshafts, and remove spacer (15).16. If necessary, remove the dowel from the end of the camshaft.Install Camshaft
Typical Example1. Put tool (A) in position on the flywheel housing as shown. Install the bolts that hold it. Do not tighten the bolts at this time.2. Install tool (B) on the end of camshaft (13).3. Install camshaft (13) in the engine until tool (B) is located in the first cam bearing.4. Rotate the camshaft, and tighten the bolts that hold tool (A) to the flywheel housing.5. Rotate the camshaft, and install it
