POWER SHIFT TRANSMISSION ARRANGEMENT 4S8595 - Caterpillar

Typical Example1. Remove nuts (1), cover (2), and the gasket.
Typical Example2. Remove four bolts (3) and automatic timing advance (4). 3. Remove gear (6) from fuel injection pump camshaft (5).Install Automatic Timing Advance
Typical Example1. Remove the plug from the timing pin hole in the fuel injection pump housing, and install tool (A) in the timing pin hole.2. Install two 7/16" x 20 NF x 4" long bolts in fuel injection pump camshaft (1). Slowly, rotate the fuel injection pump until tool (A) goes into the groove in the fuel injection pump camshaft. Remove the bolts from the camshaft.
Typical Example3. Put No. 1 piston at the top center compression position (TDC) with the following procedure:a. Remove plug (3), timing bolt (4) and cover (2) from the flywheel housing.
Typical Exampleb. Install tool (B) in the flywheel housing. 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 (4) 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 (5) for the No. 1 cylinder can be moved backward and forward. The No. 1 piston is at the top center compression position (TDC) 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 cannot be moved, the No. 1 piston is not at the top center compression position (TDC) Remove the timing 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°, and install the timing bolt again.4. Remove the timing bolt, and use tool (B) to rotate the engine in the opposite direction of normal rotation (clockwise as seen from the flywheel end of the engine) a minimum of 30°.
Typical Example5. Put gear (6) in position on the fuel injection pump camshaft.
Typical Example6. Put automatic timing advance (4) in position on the fuel injection pump camshaft, and install four bolts (3). 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 rotation until the timing bolt can be installed in the flywheel.8. Tighten the bolts that hold the automatic timing advance to the fuel injection pump camshaft to a torque of 55 7 N m (41 5 lb.ft.).9. Remove tool (A) from the fuel injection pump housing, and remove the timing bolt from the flywheel.10. Check the timing as follows:a. Rotate the engine in the direction of normal rotation (counterclockwise as seen from the flywheel end of the engine) two full turns, and install tool (A) and the timing bolt again.b. The timing is correct if tool (A) and the timing bolt can be installed at the same time.
