88807A19 Mercury CABLE ASSEMBLY

Start By:a. remove expansion tank1. Drain the coolant from the engine into a suitable container for storage or disposal.2. Turn the engine counterclockwise (as seen from the flywheel end of the engine) with Tool (A) until the No. 1 piston is at top center (TC) on the compression stroke. Install the timing bolt. Install 6V-2112 Timing Pin through the hole in the injection pump housing. See the topic, "Finding Top Center Compression Position For No. 1 Piston" in Systems Operation, Testing & Adjusting Manual, SENR5517.
Earlier 3408 The Electronic Control Module (ECM) is not located on the aftercooler on the later engines. On the later engines it is located on the rear lifting group.3. Remove four bolts (1) and bracket assembly (2).
Earlier 34084. Remove bolts (4) and (5). Remove two tube assemblies (6).5. Remove bolts (3), and nut (7). Remove cover (8).6. Inspect and replace gaskets as necessary.
Earlier 34087. Remove four bolts (9) and retainer (11). Remove timing advance unit (10).Install Automatic Timing Advance
Earlier 34081. Install automatic timing advance (10). Install retainer (11) and four bolts (9).2. Tighten the bolts (9) with fingers until there is a small amount of friction (slight drag) between the retainer and the timing advance unit (10). This friction will hold the unit against the timing gears. This prevents play (backlash) when gears are turned to the correct position.3. Remove the timing bolt. Turn the flywheel until the timing pin will go into the groove in the injection pump camshaft.4. With the timing pin installed, turn the flywheel clockwise (opposite the direction of engine rotation) a minimum of 30 degrees. The reason for this step is to be sure the play is removed from the timing gears when the engine is put on top center (TC).5. Turn the flywheel in the direction of engine rotation until the No. 1 piston of the engine is on top center compression stroke. Then turn the timing bolt into the threaded hole in the flywheel.6. Tighten bolts (9) to 25 N m (20 lb ft). Then remove the timing pin from the injection pump housing.7. Tighten bolts (9) to 230 15 N m (170 11 lb ft) for Serial Numbers 8RG1-Up and 3JK1-Up, the two electronic governor engines. Tighten bolts (9) to 136 7 N m (100 5 lb ft) for Serial Number 7BL1-Up, the mechanical governor engines. Then remove the timing bolt from the flywheel.8. Turn the crankshaft two complete revolutions and check the timing again to see that timing pin will go into the groove in the injection pump camshaft with bolt in flywheel.9. If timing is not correct, do the procedure of steps 1 through 7 again.
If the timing is correct, be sure to remove timing pin and timing bolt.
Earlier 340810. Install cover (8) and bolts (3). Install nut (7).11. Install two tubes (6) and install bolts (4) and (5).
Earlier 3408 The Electronic Control Module (ECM) is not located on the aftercooler on the later engines. On the later engines it is located on the rear lifting group.12. Install bracket assembly (2), and install four bolts (1).13. Fill the cooling system with coolant to the correct level. See the Operation & Maintenance Manual.End By:a. install expansion tankDisassemble Automatic Timing Advance
Start By:remove automatic timing advance 1. Remove flange assembly (1). 2. Remove two springs (2) and two weights (3) from drive gear assembly (4). 3. Remove two slides (5) from pistons (6).4. Separate drive gear (4) from advance sleeve (7).Assemble Automatic Timing Advance
1. Put weights (3) in position in flange assembly (1) as shown.2. Install springs (2) in flange assembly (1). 4. Use 1P-808 General Purpose Lubricant to hold slides (5) in position on gear assembly (4). Install slides (5) on pistons (6). 5. Install gear assembly (4) on flange assembly (1). Make sure slides (5) fit in grooves of the weights. 6. Install advance gear (7) to drive gear (4) and flange assembly (1).End By:a. install automatic timing advance
