0383674 EVINRUDE PISTON AND DOWEL, Std

2. Loosen three clamps (3) and remove tubes (4) and (5). 3. Remove the nuts and bracket (6) if the exhaust manifold on the right side of the machine is to be removed.4. Remove the nuts, spacers and exhaust manifold (7) from the engine. 5. Remove gaskets (8). 6. Make a separation of manifolds (9), (10) and (11).Install Exhaust Manifold
Make sure the 2P2333 Manifold Sealer does not get on the inside of each manifold. Damage to the turbocharger could be the result if the manifold sealer gets on the impeller on the turbocharger.
1. Put 2P2333 Manifold Sealer on surfaces (X) on the manifolds.2. Make a connection of manifolds (1), (2) and (3). 3. Put 5P3931 Anti-Seize Compound on the threads of studs (5). Put gaskets (4) in position on the studs. 4. Install exhaust manifold (6) or the engine. Install the spacers and nuts that hold the exhaust manifold in place. Tighten the nuts finger tight only. If the right exhaust manifold was removed, install the bracket that gives support to the shield on the end of the exhaust manifold. 5. On 3412 Generator Sets, use the sequence above to tighten the nuts to a torque of 52 7 N m (38 5 lb.ft.). 6. On 3408 Generator Sets, use the sequence above to tighten the nuts to a torque of 52 7 N m (38 5 lb.ft.). 7. Put seal (8) in position on tube (9). Install tube (9) in tube (7). Install tube (7) and tube (9) on the engine. Install the clamps on tube (8) and tube (7). 8. Install clamp (10). Install the clamp so that the bolt in the clamp is 15° 10° up from vertical as shown. Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold shield (11) in place. Install shield (11). Exhaust manifolds on the left side of the engines do not have shield (11). 9. For exhaust manifolds on the left side of the machine, install clamp (12) so that the bolt in the clamp is 45° 10° down from a horizontal line as shown.10. Install support (13). 11. Install breather tube (14). Install the bolt that holds clip (15) to the bonnet.Remove Exhaust Manifold (Watercooled)
1. Drain the cooling system to a level below that of the exhaust manifold.2. Remove bolts (1) and the two bolts behind the fuel filter. Move bracket assembly (2) away from the exhaust manifold. Do Steps 3 and 4 if the watercooled exhaust manifold on the left side (as seen from the generator end) is to be removed.3. Remove nuts, washers and bolts (3) that hold the two braces to the air cleaner housing. Loosen clamp (4). 4. Fasten tool (A) and a hoist to the air cleaner housing. Remove bolts (5) and the washers that hold air cleaner housing support (6) in position. Remove air cleaner housing and support (6) from the machine as a unit. 5. Remove nuts (7), the bolts and washers that hold elbow (9) in place. Remove elbow (9) and the gaskets.6. Remove nuts (8) and the bolts. 7. Remove elbow (10) and the gasket from the front of the manifold. 8. Remove the nuts, washers and spacers (11). Remove watercooled exhaust manifold (12) and gasket (13).9. On 3412 Generator Sets that have a watercooled exhaust manifold, use a hoist to remove the exhaust manifold. Weight is approximately 27 kg (60 lb.).10. Remove the gasket that is between the exhaust manifold and the cylinder head.
