18311T10 Mercruiser COUPLING ASSEMBLY

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. 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 plug and cover on the flywheel housing. 11. Put the gasket and cover (9) in position on the timing gear cover, and install the nuts.Disassemble Automatic Timing Advance
Start By:a. remove automatic timing advance 1. Remove four nuts (1) and remove retainer (2) from automatic timing advance. 2. Remove spring (3) and race (4). 3. Remove four capscrews (5), two retainer plates (6) and remove carrier group (7) from automatic timing advance. 4. Remove snap ring (7), tapered race (9), spool (10) and weights (11) from carrier (7). 5. Remove race (12) from carrier (7). 6. Remove four bolts (13). 7. Remove plate (14), ring (16) and ring (17) from carrier assembly (15). Remove seals (19) and (20) from carrier assembly (15). Remove seal (18) from plate (14).Assemble Automatic Timing Advance
1. Install new seals (18), (19) and (20). 2. Lubricate seal (18), (19) and (20) with engine oil then carefully install carrier assembly (15) into ring (17). Install ring (16) and plate (14). 3. Align proper bolt holes and install four bolts (13). 4. Position race (12) into carrier (7).5. Position weights (11), spool (10), tapered race (9) and snap ring (7) into carrier (7). 6. Lubricate spool (10) and lower it into position in the automatic timing advance. Position retainer plates (6) and install four capscrews (5). Tighten capscrews (5) to a torque of 3.4 0.4 N m (30 4 lb.in.). 7. Position race (4) and spring (3). When installing retainer (2), be sure spring (3) properly engages retainer adjustment screw.8. Position retainer (2) and install four nuts (1)End By:a. install automatic timing advance
