Remove Automatic Timing Advance
START BY:a) remove expansion tank (if so equipped) Steps 1 and 2 are for generator sets with expansion tanks.1. Disconnect contactor (1) from the elbow. Remove two bolts (2) that hold elbow (3) against the other elbow. 2. Remove two bolts (4). Remove the bolts that hold elbow (3) to the cylinder head. Remove elbow (5), pipe (6) and elbow (3) from the engine as a unit. 3. Remove the bolt that holds clip (7) to the cover over the automatic timing advance.4. Remove nut (8). 5.

1. Remove the plug and cover from the flywheel housing. Use tool (A) to turn the flywheel until the timing bolt can be installed in the flywheel through hole (1). Step 2 is for generator sets that have a Woodward PSG governor.2. Remove cover (2) from the governor drive housing.
Typical Example Step 3 is for generators that have a dashpot governor.4. On 3408 Generator Sets with a dashpot governor, remove plug (3). On 3412 Generator Sets with a dashpot governor, remove plug (4). 5. Turn the camshaft (5) until tool (B) can be installed in the groove (slot) in the camshaft. Remove the valve cover over the No. 1 cylinder. The engine is at top dead center on the compressor stroke if both rocker arms for the No. 1 cylinder can be moved up and down. If the rocker arms can not be moved, remove the timing bolt from the flywheel housing and turn the flywheel 360° more and install the timing bolt in the flywheel. 6. Install automatic timing advance (6), retainer (7) and four bolts (8). Tighten bolts (8) to a torque of 14 N m (10 lb.ft.). Tighten bolts (8) again to 68 N m (50 lb.ft.). Tighten bolts (8) again to a final torque of 136 7 N m (100 5 lb.ft.).7. Remove tool (B) and the timing bolt from the flywheel housing. Turn the flywheel two complete turns and install the timing bolt in the flywheel and tool (B) in the fuel injector pump housing to make sure the engine and fuel system is in the correct time.8. Remove tool (B) and install the cover (or plug) over the opening. Remove tool (A) and install the cover and plug in the flywheel housing. 9. Install bolt (9) in the cover as shown. There is not enough clearance to install bolt (9) for the expansion tank after cover (10) is installed.10. Install the gasket and cover (10). 11. Install the bolt that holds clip (11) in position on the cover. Install washer and nut (12). Steps 11 and 12 are for generator sets that have expansion tanks.12. Make sure the gasket is in position between elbow (13) and elbow (14). Make sure the gasket is in position between the cylinder head and elbow (16).13. Install elbow (14), pipe
