Start By:a. remove fuel injection linesb. remove air inlet manifoldc. remove fan drive Fluid Spillage ContainmentCare must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates.
Typical Example1. Remove the bolts, and remove adapter (1) from over the tachometer drive shaft.
Typical Example2. Remove tachometer drive shaft (2) and the washer that hold the drive gear on the fuel injection pump camshaft.
Typical Example3. Install Tool (A), and use it to loosen the drive gear on the fuel injection pump camshaft. Remove Tool (A). 4. Disconnect wires (3) from the fuel shutoff solenoid and the wire from the switch.5. Disconnect fuel supply tube (5) from the fuel injection pump housing.6. Remove fuel return tube (4) from the fuel injection pump housing and the engine. 7. Remove two bolts (7), and remove fuel injection pump housing and governor (6) from the engine.Install Fuel Injection Pump Housing & Governor
1. Clean and inspect O-ring seals (1) and (2). Make a replacement of the seals if worn or damaged. 2. Install Tool (B) in the fuel injection pump camshaft. Remove the plug from the cover on the fuel injection pump housing, and install Tool (A). Use Tool (B) to turn the camshaft until timing pin [Tool (A)] can be pushed into the groove (slot) in the fuel injection pump camshaft. 3. Put fuel injection pump housing and governor (3) in position on the engine. Install the two bolts that hold the unit in position. 4. Remove the electric starting motor, and install Tool (C) in the flywheel housing to turn the engine.
Typical Example5. Install the washer and tachometer drive shaft (4), but do nottighten shaft (4).6. Remove the cap and fitting from the front housing at location (5).7. Install a 5/16 -18 NC X 63 mm (2 1/2 in) Long Bolt. The cover bolt from hole (7) can be used. Use Tool (C) to turn the crankshaft clockwise (as seen from front of engine) until bolt (6) can be installed in the camshaft gear and is in the center of the timing hole. With timing pin (A) in the groove (slot) in the fuel injection pump camshaft and bolt (6) in the hole in the engine camshaft gear, the timing for the engine is correct. Tighten tachometer drive shaft (4) to a torque of 149 14 N m (110 10 lb ft).8. To check the timing, remove timing pin (A) and bolt (6). Turn the crankshaft with Tool (C) clockwise (as seen from front of engine) two revolutions, and install the timing pin (A); then bolt (6) back in place. If bolt (6) cannot be installed, the timing is not correct. The procedure must be done again. Do notturn the crankshaft counterclockwise (as seen from the front of the engine) to install bolt (6). The drive gear on the fuel injection camshaft must be loosened to change the timing.
Typical Example9. Install adapter (8) over the tachometer drive shaft.10. Remove bolt (9) from the camshaft gear, and install it back in its original position in the front housing.11. Install the fitting and cap in the front housing. 12. Remove timing pin [Tool (A)], and install the plug in the cover on the fuel injection pump housing. 13. Connect wires (11) to the fuel shutoff solenoid.14. Install fuel supply tube (12) to the fuel injection pump housing.15. Connect fuel return tube (10) to the fuel injection pump housing.16. Connect the wires to the switch on the fuel injection pump housing.End By:a. install fan driveb. install air inlet manifoldc. install fuel injection lines
