BRACKET AS 3669502 - Caterpillar

Start By:a. remove fuel injection linesb. remove belt tightener Put caps or plugs on all fuel system openings to keep dirt and other foreign material out of the fuel system. 1. Put alignment marks on the governor shaft and lever (1) for correct alignment during installation. Disconnect lever (1) from the governor.2. Disconnect fuel lines (2) and (4) from the fuel injection pump.3. Disconnect fuel lines (5) and (6) from the fuel transfer pump.4. Remove bolt (3) and plug (7) from the timing gear cover. 5. Loosen bolt (8) that holds the fuel pump drive gear to the fuel injection pump camshaft a maximum of one turn. 6. Remove three bolts (9).7. Loosen three nuts (10) that hold the fuel injection pump housing to the timing gear plate. Loosen the nuts until they are even with the end of the studs.
Tooling (A) must be installed in the position shown so the locks will not damage the wear passage in the timing gear cover.
8. Loosen the drive gear from the fuel injection pump camshaft with tooling (A) as follows:a. Install tooling (A) in the position shown, and tighten the locks to hold the tooling in place.b. Turn the extension counterclockwise to loosen the bolt in the fuel injection pump camshaft. As the bolt is loosened, it will push against tooling (A), and push the fuel injection pump camshaft out of the drive gear.c. Remove tooling (A) from the timing gear cover. Remove the bolt and washer from the fuel injection pump camshaft.9. Remove three nuts (10). See illustration B91140P1, and remove the fuel injection pump housing and governor from the engine. The weight of the fuel injection pump housing and governor is 22 kg (49 lb).Install Fuel Injection Pump Housing And Governor
1. Install the fuel injection pump housing and governor on tooling (A), or use a suitable vise to hold the unit.2. Remove bolts (2), cover (1) and the gasket from the fuel injection pump housing. 3. Install the bolt and washer used to hold the drive gear to fuel injection pump camshaft (3).4. Install tool (B) in the hole of the fuel injection pump housing. Turn fuel injection pump camshaft (3) until timing pin (B) engages in the notch in the fuel injection pump camshaft. Tool (B) will hold the fuel injection pump camshaft in the correct position to set the fuel injection timing of the engine. 5. Be sure O-ring seals (4) and (5) are in position on the governor and the fuel injection pump housing. 6. Put the fuel injection pump housing and governor in position on the engine, and install three nuts (7).7. Install three bolts (6). Bolt (8) must be tight enough to hold the gear clearance (backlash) out of the timing gears when the engine is turned. However, the timing gear must be able to turn on the shaft when the engine is turned to put the No. 1 piston on the top center compression position (TDC).8. Put clean oil on the threads
