1. Remove two bolts (1). Remove two nuts (2). 2. Open infill assembly access door (4).3. Disconnect two fuel lines (3). 4. Remove five bolts (5). Four bolts are on radiator shroud. One bolt is on engine hood group.5. Set infill assembly aside. 6. Loosen bolt (11).7. Loosen tension nut (10).8. Remove two nuts (9). Reposition bracket (8).9. Remove six nuts (6). Remove cone (7). Inspect gasket for damage, replace if necessary. 10. Remove four nuts (12).11. Remove automatic timing advance (13). 12. Remove gear (14) from fuel injection pump camshaft (15).Install Automatic Timing Advance
Typical Example1. Remove the plug from the timing pin hole in the fuel injection pump housing, and install tool (A) in the timing pin hole.2. Install two 7/16" x 20 NF x 4" long bolts in fuel injection pump camshaft (1). Slowly, rotate the fuel injection pump until tool (A) goes into the groove in the fuel injection pump camshaft. Remove the bolts from the camshaft. 3. Put No. 1 piston at the top center compression position (TDC) with the following procedure:a. Remove plug (3), timing bolt (4) and cover (2) from the flywheel housing. b. Install tool (B) in the flywheel housing. Use tool (B) to slowly rotate the engine in the direction of normal rotation, (counterclockwise as seen from the flywheel end of the engine), until timing bolt (4) can be installed in the flywheel housing and into the hole in the flywheel. c. Remove the valve cover from the valve cover base. Check to see if both rocker arms (5) for the No. 1 cylinder can be moved backward and forward. The No. 1 piston is at the top center compression position (TDC) when the timing bolt is installed in the flywheel and both rocker arms for the No. 1 cylinder can be moved backward and forward. If both rocker arms cannot be moved, the No. 1 piston is not at the top center compression position (TDC) Remove the timing bolt from the flywheel and rotate the engine in the direction of normal rotation, (counterclockwise as seen from the flywheel end of the engine one full turn 360°, and install the timing bolt again.4. Remove the timing bolt, and use tool (B) to rotate the engine in the opposite direction of normal rotation (clockwise as seen from the flywheel end of the engine) a minimum of 30°. 5. Put gear (6) in position on the fuel injection pump camshaft. 6. Put two O-ring seals (8) in position on automatic timing advance (7).7. Put automatic timing advance in position on the fuel injection pump camshaft, and install the four bolts. Tighten the bolts to a torque of 3 N m (27 lb in).8. Use tool (B) and slowly rotate the engine in the direction of normal rotation until the timing bolt can be installed in the flywheel.9. Tighten the bolts that hold the automatic timing advance to the fuel injection pump camshaft to a torque of 55 7 N m (41 5 lb ft).10. Remove tool (A) from the fuel injection pump housing, and remove the timing bolt from the flywheel.11. Check the timing as follows:a. Rotate the engine in the direction of normal rotation (counterclockwise as seen from the flywheel end of the engine) two full turns, and install tool (A) and the timing bolt again.b. The timing is correct if tool (A) and the timing bolt can be installed at the same time. The timing procedure must be done again if the timing bolt and tool (A) can not be installed at the same time.c. Remove tool (A), and install the plug in the fuel injection pump housing. Remove the timing bolt and tool (B), and install the plug and cover on the flywheel housing. 12. Put gasket (10) and cover (9) in position on the timing gear cover. 13. Install six nuts (10).14. Position bracket (11). Install two nuts (12).15. Tighten tension nut (13).16. Tighten bolt (14). 17. Install five bolts (15). Four bolts are to the radiator shroud. One bolt is to the engine hood group. 18. Connect two fuel lines (16). 19. Install two bolts (17). Install two nuts (18).End By:lower cabDisassemble Automatic Timing Advance
Start By:a. remove automatic timing advance 1. Remove seals (1) from the body.
Spring force is present behind carrier (3). To prevent personal injury, put downward pressure on carrier (3) when bolts (2) are removed.
2. Remove bolts (2) from ring (4). 3. Remove ring (4) and the carrier from ring (5). 4. Remove springs (6) and ring (5) from retainer assembly (7). 5. Remove the locknut and setscrew (8). Remove the locknut and screw (9) from the retainer assembly. 6. Remove ring (4) from carrier (3).7. Remove seal (10) from carrier (3). 8. Remove bolts (11) and carrier (12) from carrier (3). 9. Remove lockring (13) and body (14) from the carrier. 10. Install two 3/8"-16 NC bolts into the body as shown. Clamp the bolt heads in a vise, and remove plug (15) from body (14). 11. Remove ring (16) and race (17) from spool (18), and remove spool (18) from the carrier. 12. Remove dowels (19) and flywheights (20) from the carrier.Assemble Automatic Timing Advance
1. Put flyweight (1) in position on carrier (2), and install dowels (3) that hold the flyweights in position. 2. Put spool (4) in position on the carrier, and install race (5) and ring (6) on the end of spool (4). 3. Install two 3/8"-16 NC bolts into body (7) as shown. Clamp the bolt heads in a vise, and install plug (8). Tighten plug (8) to a torque of 70 15 N m (50 11 lb ft). 4. Install body (7) into carrier (8), and install lockring (9). 5. Put carrier (2) in position on carrier (8), and install the bolts that hold it. 6. Install seal (9) on carrier (8). Put clean engine oil on the seal, and install ring (10) on carrier (8). 7. Install setscrew (11) and the locknut. Install
