HOUSING 8S2627 - Caterpillar

9. Remove six fuel injection lines (8). Put protective caps in the fuel injection lines and on the fuel injection pumps to keep dirt and debris out of the fuel system. The bolts used to hold the electric starting motor to the flywheel housing can be used to hold tool (B) in position.10. Install tool (B) in the flywheel housing at the location for the electric starting motor.11. Remove timing pin plug (14) from the flywheel housing.12. Use the following procedure to put the No. 1 piston at top center on the compression stroke. No. 1 piston, at top center (TC) on the compression stroke, is the starting point for all timing procedures:
The engine is viewed from the flywheel end when the direction of rotation is given. Do not turn the flywheel backwards.
a. Using tool (B), rotate the flywheel counterclockwise until tool (C) can be installed through the opening in the flywheel housing and into a hole in the flywheel. Do not turn the flywheel backwards. b. Remove bolt (15) and breather assembly (16) from the valve cover. By looking through the breather hole in the valve cover, check to see if both rocker arms for the No. 1 piston are loose and can be moved backward and forward by hand. If both rocker arms do not move, then the No. 1 piston is not at top center of the compression stroke.c. If the No. 1 piston is not at top center of the compression stroke, remove tool (C) from the flywheel. Using tool (B), rotate the flywheel counterclockwise 360°. Reinstall tool (C) into the hole in the flywheel. Check to see if both rocker arms for the No. 1 piston are loose and can be move backward and forward by hand. If free movement is felt, the No. 1 piston is at top center of the compression stroke. 13. Remove four bolts (17), cover (19) and the gasket from the side of the fuel injection pump housing.14. Remove six nuts (20), the washers, cover (18) and the gasket from the front housing. 15. With cover (19) removed, install tool (C) into the groove of the injection pump camshaft.16. Remove bolt (21) and the washer that hold fuel pump drive gear (22) in position. 17. Install tool (D) as shown, and loosen fuel pump drive gear (22) from the end of the camshaft. 18. Fasten a lifting strap and a hoist to fuel injection pump housing and governor (23) as shown.19. Remove two bolts (24) and the washers that hold the fuel injection pump housing and governor to the oil manifold.
Be sure tool (C) stays in the groove of the camshaft when the fuel system is removed from the machine.
20. Remove three nuts (25) and the washers that hold the fuel injection pump housing and governor to the timing gear plate. Remove fuel injection pump housing and governor (23). The weight of the fuel injection pump housing and governor is 27 kg (60 lb). the following steps
