start by: a) remove timing gear cover and oil pumpb) remove valve lifters 1. Remove the plug from the fuel injection pump housing and install timing pin (A).2. While turning the crankshaft clockwise as seen from the front of the engine, push on timing pin (A) until it slides into the groove (slot) in the fuel injection pump camshaft.3. Remove the tachometer drive adapter shaft and install tooling (B) as follows: a) Install bolt assembly (3) in the fuel injection pump camshaft. The bolt assembly must turn freely into the camshaft. Do not use force to install the bolt assembly.b) Install bolt (2) in the drive gear for the fuel injection pump camshaft.c) Tighten the bolt and remove drive gear (1).d) Remove tooling (B). 4. Remove thrust pin (4) that holds the camshaft in place from the rear of the cylinder block.5. Remove the camshaft and gears from the cylinder block as a unit. Be careful not to cause damage to the camshaft bearings or journals. If the gears are to be removed from the camshaft, see CAMSHAFT GEARS.Install Camshaft And Gears (Engines With Taper Drive For Fuel Injection Pump)
1. Put clean engine oil on the camshaft lobes and journals. Install camshaft (1) and the gears as a unit. Make sure the timing marks on the crankshaft gear and camshaft gear are in alignment. 2. Install the thrust pin. Tighten the pin to a torque of 35 5 lb.ft. (4.8 0.7 mkg). 3. Put gear (3) in position and install tachometer drive adapter shaft (2). Tighten the shaft to a torque of 32 2 lb.ft. (4.4 0.3 mkg).4. After valve lifters and timing gear cover have been installed, check the timing as follows: a) Remove timing pin (A).b) Turn the crankshaft clockwise as seen from the front of the engine approximately 1/2 turn. Install timing pin (A) again.c) While turning the crankshaft clockwise, push on timing pin (A) until it slides into the groove (slot) in the fuel injection pump camshaft. d) Remove plug (4) from the timing hole. Remove bolt (5) and install it through the timing hole and into the camshaft gear. The timing is correct when timing pin (A) is installed in the fuel injection pump camshaft and bolt (5) is installed in the camshaft gear.e) Remove the bolt and install the plug. Remove timing pin (A) and install the plug. If the bolt can not be installed in the camshaft gear, the timing must be corrected as follows: a) With timing pin (A) installed, remove the tachometer drive adapter housing and shaft.b) Loosen the gear from the fuel injection pump camshaft. Turn the crankshaft clockwise approximately two full turns until bolt (5) can be installed. Install the bolt.c) Install tachometer drive adapter shaft and tighten it to a torque of 32 2 lb.ft. (4.4 0.3 mkg). Install adapter housing. Remove the bolt and timing pin and install the plugs.end by: a) install valve liftersb) install timing gear cover and oil pump
