Remove four bolts (3) and retainer (5) from automatic timing advance (4). Remove the automatic timing advance.Install Automatic Timing Advance
1. Put automatic timing advance (1) in position on the fuel injection pump camshaft. Make alignment of the gears with the timing gears in the timing gear housing.2. Install the retainer and bolts that hold the automatic timing advance. Tighten the bolts to a torque of 68 N m (50 lb.ft.) with the timing pin in the fuel injection pump camshaft.3. Remove the timing pin and tighten the bolts to a torque of 136 7 N m (100 5 lb.ft.). If replacement of the stud for the automatic timing advance cover is needed, put PERMATEX Form-A-Gasket No. 2 or the equivalent on the threads of the new stud. Tighten the stud to a torque of 27 4 N m (20 3 lb.ft.). 4. Install the gasket and automatic timing advance cover (2) on the timing gear housing. Install the bolts and nuts that hold the timing advance cover on the timing gear housing.5. Put the fuel filter base and muffler support brackets in position on the engine and install the bolts and nuts to hold them.6.

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
