3827825 Volvo.Penta Insert

TYPICAL EXAMPLE2. Remove tube assembly (1). Loosen hose clamp (2) between the cylinder head and timing gear cover. 3. Disconnect air cleaner indicator line (4) from the fitting in the air inlet manifold.4. Disconnect ether starting aid line (3) from the air inlet manifold.5. Remove two clips (5) that hold the water temperature sensing line in place. 6. Install a 5/16"-18 NC forged eyebolt (7) and fasten a hoist. Remove the twenty-two bolts that hold the cylinder head to the cylinder block. Remove cylinder head (6). The weight is 120 lb. (54 kg).Install Cylinder Head
1. Clean the surfaces of the cylinder head and the cylinder block that make contact with each other. Make sure the surfaces are clean and dry. Install a new, dry gasket on the cylinder block.
TYPICAL EXAMPLE2. Inspect the condition of water ferrule and seal (2). Make a replacement if needed. Put water ferrule and seal (2) in position with the adjusting screw of hose clamp (1) toward the top and approximately 45° to the right of vertical as seen from the front of the engine.3. Make sure the seal is installed all the way with counterbore. 4. Install a 5/16"-18 NC eyebolt in the head and fasten a hoist. Put cylinder head (3) in position on the cylinder block. If plugs (4) and (5) were removed, put 5P3413 Pipe Sealant on the threads and install the plugs in the head.5. Put 5P3931 Anti-Seize Compound on all the threads of the head bolts.
HEAD BOLT LOCATION AND TIGHTENING SEQUENCE6. Install the head bolts and tighten as follows: a) Tighten bolts (1) to (18) by number sequence to a torque of 60 10 lb.ft. (80 14 N m).b) Tighten bolts (1) to (18) by number sequence to a torque of 110 5 lb.ft. (150 7 N m).c) Tighten bolts (1) to (18) again by number sequence to a torque of 110 5 lb.ft. (150 7 N m).d) Tighten bolts (19) to (22) by number sequence to a torque of 32 5 lb.ft. (43 7 N m). 7. Tighten hose clamp (1).8. Install tube assembly (6). 9. Install two clips (9) that hold the water temperature sensing line in place.10. Connect ether starting aid (7) to the air inlet manifold.11. Connect air filter indicator line (8).12. Fill the cooling system with coolant. See LUBRICATION AND MAINTENANCE GUIDE.end by:a) install exhaust manifoldb) install fuel injection nozzlesDisassemble Cylinder Head
start by:a) remove cylinder heads 1. Fasten a hoist and put the cylinder head in position on tool (A). Use adapter plates (1) from tooling (A) to hold the head in place. 2. Put the valve springs under compression with tool (C).3. Remove the locks from the valves.4. Remove tool (C), retainer, spring, washer and valve from the cylinder head. Put identification on the valve as to its location in the cylinder head. 5. Check the valve spring force with tool (B). Spring force must be 35 5 lb. (155 22 N) when the length of the spring force is 1.715 in. (43.56 mm).6. Do Steps 2 through 5 for the remainder of the valves. 7. Remove the valve seat inserts with tooling (D). The valve guides are part of the cylinder head. Measure the bore in each valve guide .75 in. (19.0 mm) from the outside edge on both ends of each valve guide. The bore must be .3745 .0005 in. (9.512 0.013 mm). The maximum permissible bore is .3760 in. (9.550 mm). Valve guides worn more than the maximum specification can be made to the original size by knurling. See RECONDITIONING PROCEDURES FORM NO REG00867.Assemble Cylinder Head
1. Clean and remove burrs and all foreign material from the valve seat bores. 2. Lower the temperature of the valve seat inserts and install them with tooling (A).
Do not make the diameter of the extractor (part of tooling A) in valve seat insert larger when the insert is installed in the cylinder head.
3. Grind the valve inserts according to specifications given in ENGINE SPECIFICATIONS. 4. Put clean engine oil on the valve stem. Install the valve, washer (3), spring (2) and retainer (1) in the cylinder head. 5. Put the valve spring under compression with tool (C).6. Install the locks on the valve stem with tool (B).
Make sure locks (4) are in their correct position on the valve. The locks can be thrown from the valve when tool (C) is released if the locks are not in their correct position on the valve.
7. Remove tool (C) and hit the valve with a rubber hammer to be sure the locks are in their correct position.8. Do Steps 4 through 7 for the remainder of the valves.end by:a) install cylinder heads
