0342358 JOHNSON BOLT, Bearing housing

start by:a) remove hood, muffler and precleaner assemblyb) remove fuel injection linesc) remove fuel filter and based) remove fuel priming pump The radiator guard is removed from the machine for better photo illustration for the removal of the fuel injection pump housing and governor. 1. Disconnect rod assembly (2) from the lever on the governor.2. Remove breather tube (3).3. Remove drain hose (1) from the fuel system. 4. Remove plug (4). Tooling (A) can be used to turn the engine to put the No. 1 piston on top center (TC) compression. If tooling (A) is used, remove the electric starting motor and install tooling (A) in the flywheel housing. If tooling (A) is not used, the engine can be turned with the bolt that holds the pulley for the vibration damper.5. Put the No. 1 piston at top center (TC) compression as follows: a) Turn the crankshaft clockwise (as seen from the front of the engine) until a 3/8"-16 NC bolt can be installed in the hole from which plug (4) was removed. The bolt must go through the hole in the flywheel housing and into the threaded hole in the flywheel. Never turn the crankshaft counterclockwise to install the bolt in the flywheel.b) Disconnect the breather group from the valve cover. The rocker arms for the No. 1 piston can be seen through the breather hole.c) Check to see if both rocker arms can be moved backward and forward by hand through the breather hole.d) If both rocker arms can not be moved, the No. 1 piston is not at the top center (TC) compression position. Remove the bolt from the flywheel. Turn the engine clockwise as seen from the front of the engine one full turn 360° and install the bolt again. 6. Remove timing pin (5) from location (6).7. Install timing pin (5) in the groove (slot) in the fuel injection pump camshaft. 8. Remove nuts (7) and cover (8) from the timing gear cover. Remove vee belts. 9. Remove bolt (9) and the washer and install tooling (C) on the end of bolt (9). Install and tighten the bolt, washer and tooling (C) to hold the sleeve on the end of the fuel injection pump camshaft. 10. Install tooling (B) on the drive gear as shown. Tighten the center bolt of tooling (B) until the drive gear is loose. Remove tooling (B), bolt (9) and the washers. The drive gear will stay in the timing gear cover. 11. Fasten a hoist to the fuel injection pump housing and governor (10). Remove bracket (11). Remove three nuts (12) and remove the fuel injection pump housing and governor. The weight of the fuel injection pump housing and governor is 50 lb. (23 kg). Check the condition of the O-ring seal in the body assembly of the fuel transfer pump. If the seal has damage, use a new part for replacement.Install Fuel Injection Pump Housing And Governor (Sleeve Metering Fuel Injection)
1. Make sure the No. 1 piston is in the top center (TC) compression position. Make sure the timing pin for the fuel system is in the groove (slot) in the fuel injection pump camshaft. 2. Install a new O-ring seal (1) in the body assembly of the fuel transfer pump. 3. Fasten a hoist to fuel injection pump housing and governor (2) and put the unit in position on the timing gear plate. Install the three nuts and washers that hold it. Install bracket (3). 4. Put the drive gear (4) in position on the fuel injection pump camshaft. Install the washer and bolt that hold the gear. 5. Install tooling (A) in the holes of the fuel injection pump drive gear. Put a torque of approximately 50 lb.ft. (70 N m) on the pump drive gear in a clockwise direction as seen from the front of the engine. With the clockwise torque on the pump drive gear, tighten the bolt to a torque of 110 5 lb.ft. (149 7 N m). 6. Install the gasket and cover (5). Tighten the nuts that hold cover (5) to a torque of 20 5 lb.ft. (25 7 N m). 7. Remove timing pin (6) from location (7) and install in its original location. Install the bolt that was removed from location (7). 8. Remove bolt (8) from the flywheel and install the plug in the flywheel housing.9. If an engine turning tool was used, install the electric starting motor (9). 10. Install drain hose (13).11. Install breather tube (10) and vee belts (12).12. Connect rod assembly (11) to the lever on the governor.end by:a) install fuel priming pumpb) install fuel filter and basec) install fuel injection linesd) install hood, muffler and precleaner assembly
