start by: a) remove rocker shafts and push rodsb) remove intake manifolds1. Remove the instrument panel from cylinder head to be removed (if so equipped).2. Remove the coolant from engine.3. Remove the eight bolts for each cylinder head from the exhaust manifold on the marine engines. 4. Remove the bolts that hold the plate (2) on bottom of exhaust shield. Let the plate lay in the "V" of engine.5. Remove the plugs (1) from the shield.6. Remove the eight bolts that hold the exhaust manifold to each cylinder head. 7. Remove the fuel lines (5) for the head to be removed. Put covers on fuel valves, lines, and pumps. Remove two elbows (4) for each cylinder head. Remove the governor control channel for cylinder heads on left hand side only.8. Remove the oil line (3) for the rocker shaft.9. Remove the nuts (6) from the cylinder head. 10. Install two 1/2"-13 NC forged eyebolts in head.11. Fasten a hoist to the eyebolts and slowly remove the cylinder head. Weight is 190 lb. (86 kg).Install Cylinder Heads
1. Clean the block and cylinder head. Install new head gaskets, new water seals, and ferrules.2. Install two 1/2"-13 NC forged eyebolts in head. Fasten a hoist and slowly lower the head over the studs until it is in correct position over head gaskets and seals. Weight is 190 lb. (86 kg).3. Put 5P3931 Anti-Seize Compound on threads of head studs, and on the bolts for exhaust manifold. Install nuts and washers on studs. Tighten nuts in following step sequence: 1 Tighten nuts by number to a torque of 150 10 lb. ft. (205 14 N m).2 Tighten nuts by number to a torque of 250 10 lb. ft. (340 14 N m).3 Tighten nuts again by number (hand torque only) to a torque of 250 10 lb. ft. (340 14 N m). 4. Install new gaskets for the exhaust manifold. Install the bolts (1) that hold exhaust manifold to head. Tighten bolts (1) to a torque of 110 10 lb. ft. (149 14 N m) on Marine Engines. Tighten bolts (1) on Industrial Engines to 75 10 lb. ft. (100 14 N m).5. Install the plate and plugs on the shield for the manifold bolts (if so equipped). 6. Install the oil line (2) for the rocker shaft.7. Install the two elbows (3). Install the fuel lines. Tighten nuts (4) on fuel lines to a torque of 25 to 35 lb. ft. (35 to 45 N m). Install governor control channel (on left hand side only).8. Install the instrument panel on cylinder head removed (if so equipped).9. Fill the engine with coolant to correct level.end by: a) install intake manifoldsb) install rocker shafts and push rods
