Turn the engine counterclockwise (as seen from the flywheel end of the engine) with tool (A) until the No. 1 piston is at top center (TC) on the compression stroke and the timing bolt can be installed in the flywheel. See Top Center (TC) Position For No. 1 Piston in Testing And Adjusting section. 2. Remove 10 bolts (1) and two nuts (2) (top nut is not shown). Remove cover (3). 3. Remove four bolts (4) and the retainer.4. Remove automatic timing advance (5).Install Automatic Timing Advance
1. Put automatic timing advance (2) in position in housing (1). Install the retainer and bolts (4).2. Check fuel injection pump timing with tool (B). See Fuel Injection Pump Timing in Testing And Adjusting section.3. Tighten bolts (4) evenly to a torque of 25 N m (18 lb.ft.).4. Tighten bolts (4) to a torque of 135 7 N m (100 5 lb.ft.).

START BY:a. remove automatic timing advance 1. Remove ring (1) and gear assembly (2) from the flange assembly.2. Remove the slides from the weights. 3. Remove springs (4) and weights (3) from the flange assembly.Assemble Automatic Timing Advance
1. Put weights (2) in position in flange assembly (1) as shown.2. Install springs (3) in flange assembly (1). 3. If pistons (6) were removed from the gear assembly because of wear, use new parts for replacement. Install new pistons (6) until they are 11.05 0.13 mm (.435 .005 in.) above the inside surface of gear assembly (4). Move the metal (peen) on the outside surface of gear assembly (4) in four places around each piston to hold them in position.4. Use 1P808 General Purpose Lubricant to hold slides (5) in position on gear assembly (4).5. Install gear assembly (4) on flange assembly (1). Make sure slides (5) fit in grooves of the weights.6. Install the ring that holds gear assembly (4) to the flange assembly.END BY:a. install automatic timing advance
