809724 Mercruiser SCREW

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 And 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 × 4" 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 (TDC) 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 flywheelend of the engine) one full turn (360°), 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 rotation until the timing bolt can be installed in the flywheel.8. Tighten the bolt that holds ring (5) 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, and 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. The timing procedure must be done again if the timing bolt and tool (A) can not be installed at the same time.c. Remove tool (A), and install the plug in the fuel injection pump housing. Remove the timing bolt and tool (B), and install the cover and plug in the flywheel housing. 11. Put O-ring seals (7) on cover (6). Put clean engine oil on the O-ring seals.12. Install cover (6) on the ring, and install the bolts that hold it. 13. Put the gasket and cover (8) in position on the timing cover. Put the hose and clip (9) in position, and install the bolts that hold the cover and clip to the timing cover.
