0382388 JOHNSON THRUST MOUNT ASSEMBLY, Lower exhaust housing

3. Remove the bolts (1) that hold inspection covers to block. Remove the covers (2). 4. Turn the crankshaft (in the direction of normal rotation) until the rod caps (4) can be removed through the openings. Remove the bolts (3) and rod caps (4). 5. Remove the carbon ridge (5) from the top of the cylinder liner. 6. Push the connecting rod and piston up until rings are out of the cylinder liner.7. Remove the piston and connecting rod from the cylinder liner. Weight is 45 lb. (20 kg).Install Pistons
1. Put clean SAE 30 engine oil on the piston, rings, connecting rod bearings and walls of cylinder liner. Install upper bearing in connecting rod. 2. Install piston (1) in tool (A). Put the piston and tool (A) in position on the cylinder liner as shown.3. Install the piston in the liner slowly on to the journal of crankshaft. Be sure the "V" mark on piston is in alignment with the "V" mark (2) on the block.
Be careful not to cause damage to connecting rod bearing or journal on crankshaft when piston is installed.
4. Install the lower bearing (5) in the cap (3) for the connecting rod (4). Be sure the tab on back of bearing fits in groove for tab in cap. Install the cap.
TYPICAL EXAMPLE5. Put 5P3931 Anti-Seize Compound on threads of rod bolts. Install rod bolts. Tighten the rod bolts to a first torque of 40 4 lb. ft. (55 5 N m). Put a mark on bolt heads and bearing caps. Tighten the bolts again 120° from the mark.6. Put inspection covers in position on engine. Install the bolts that hold covers to cylinder block.7. Install the wire harness and plate for the prelubrication oil pump and motor (if so equipped).8. Put the prelubrication oil pump and motor on engine with a hoist.end by: a) install oil pump pressure regulator valveb) install engine oil pumpc) install jacket water pumpd) install engine oil coolere) install cylinder headDisassemble And Assemble Pistons
start by: a) remove piston 1. Remove retainers (5) and pin (3) from the piston. Remove connecting rod (2) from the piston. 2. Use tool (A) to remove the piston rings from the piston.
Do not use a broken ring or carbon scraper to clean carbon. They will cut the ring grooves or cause damage to piston.
3. Remove the carbon from ring grooves on piston. 4. Use tooling (B) to remove and install the piston pin bearing. See Special Instruction, Form SMHS7295, for more information.5. Use the ring expander (A) to install the piston rings.6. Install spring for oil control ring (bottom ring) in the bottom ring groove of piston. Install oil control ring.7. Install center ring in center groove of piston so the mark "UP-2" on ring is toward top of piston. Install top ring in top groove of piston so the mark "UP-1" on ring is toward top of piston.8. Turn the piston rings in the grooves so the ring gaps are 120° apart.9. Put the connecting rod (2) so the bearing cap (1) is turned up. Put the piston with relief (4) for valves is turned up and "V" mark (6) is down. Install pin (3) and two retainers (5). Each retainer (5) must fit in a groove in piston on each end of pin (3).end by: a) install pistons
