WIRING GP-ENGINE 3715752 - Caterpillar

start by:a) remove hood 1. Remove the panel assembly from the left side of the rear frame.2. Shut off the fuel supply line to the engine.3. Disconnect linkage (5) from the governor control lever.4. Remove drain hose (7) from the fuel injection pump housing.5. Disconnect fuel lines (1), (2) and (8) from the fuel injection pump.6. Remove fuel injection lines (3) from the engine.
Put protection caps (5F2807) and plugs (2F2990) on the fuel injection lines, pumps and fuel injection nozzles to keep dirt and foreign material out of the fuel system. Also put caps and plugs on all other fuel system openings.
7. Loosen the adjustment nuts and bolts for the alternator to remove the tension on belts (4). Remove belts (4) from the engine.8. Remove cover (6) from over the fuel injection pump drive gear. 9. Remove bolt (9) and the washer and install tooling (B) on the end of bolt (9). Install and tighten the bolt, washer and tooling (B) to hold the sleeve on the end of the fuel injection pump camshaft. 10. Install tooling (A) on the drive gear as shown. Tighten the center bolt of tooling (A) until the drive gear is loose. Remove tooling (A), bolt (9) and the washers. The drive gear will stay in the timing gear cover.
TYPICAL EXAMPLE11. 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
1. Put the No. 1 piston at the top center compression position before the fuel injection pump housing and governor are installed on the engine with the following procedure: a) Remove plug (1). 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.b) 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 (1) 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. If the crankshaft is turned counterclockwise the gear clearance (backlash) can cause the engine to be out of time when the fuel injection pump housing and governor are installed.
c) Disconnect breather tube (2) and the glow plug wire assembly from the valve cover. Remove valve cover (3) from the engine.d) Check to see if both
