ENGINE AR-PRIMARY 1065002 - Caterpillar

Fuel Injection Pump & Governor Drive
FLUID SPILLAGE CONTAINMENT Care 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 PRODUCT GUIDE, NENG2500", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. 1. Remove nuts (1), and move clip (2) and the hose away from cover (3).2. Remove cover (3) and the gasket. 3. Remove the bolts that hold cover (4) to the ring, and remove the cover. 4. Remove the four bolts and ring (5). 5. Remove gear (7) from the front of fuel injection pump camshaft (6).Install Fuel Injection Pump & Governor Drive
1. Remove the plug from the timing pin hole, and put Tool (A) in the timing pin hole.2. Install two 7/16 -20 NF × 102 mm (4 in) long bolts in fuel injection pump camshaft (1). Slowly rotate the fuel injection pump camshaft until Tool (A) goes into the groove in the fuel injection pump camshaft. Remove the bolts. 3. Put No. 1 piston at the top center compression position (TC) with the following procedure. a. Remove the plug and cover from the left side of the flywheel housing, and install Tool (B) in the flywheel housing.b. Use Tool (B) to slowly rotate the engine in the direction of normal rotation (counterclockwise as seen from the flywheel end of the engine) until timing bolt (2) [the long bolt that holds the cover to the flywheel housing] can be installed in the flywheel housing and into the hole in the flywheel. c. Remove the valve cover from the valve cover base. Check to see if both rocker arms (3) for the No. 1 cylinder can be moved backward and forward. The No. 1 piston is at the top center compression stroke when the timing bolt is installed in the flywheel and both rocker arms for the No. 1 cylinder can be moved backward and forward. If both rocker arms can not be moved, the No. 1 piston is not at the top compression position. Remove the bolt from the flywheel and rotate the engine in the direction of normal rotation (counterclockwise as seen from the flywheel end of the engine) one full turn 360 degrees and install the timing bolt again.4. Remove the timing bolt and rotate the engine opposite the direction of normal rotation (clockwise as seen from the flywheel end of the engine) for a minimum of 30 degrees. 5. Put gear (4) in position on the fuel injection pump camshaft. 6. Put ring (5) in position on the fuel injection pump camshaft and install the four bolts that hold it. Tighten the bolts to a torque of 3 N m (27 lb in).7. Use Tool (B) and slowly rotate the engine in the direction of normal
