PROCEDURE
REMOVE INTAKE VALVE
Using SST, compress the 8 compression springs and remove the 8 valve spring retainer locks.
Remove the 8 valve spring retainers, 8 compression springs and 8 intake valves from the cylinder head sub-assembly.
Tech Tips
Arrange the removed parts in such a way that they can be reinstalled to their original locations.
REMOVE EXHAUST VALVE
CAUTION:
The exhaust valve is filled with sodium. Sodium is a strong alkali which can produce a dangerous chemical reaction. Be very careful when handling and disposing of it.
Do not intentionally expose the sodium in exhaust valve. If sodium enters your eyes, vision loss may occur. If sodium contacts your skin, burns may occur. If a fire occurs due to a chemical reaction with sodium, burns may occur.
If the sodium in the exhaust valve is exposed, perform all necessary preparations to safely remove and dispose of the sodium.
When removing a damaged exhaust valve, always wear rubber gloves and safety glasses.
Do not intentionality cut or break open the exhaust valve to remove the sodium.
Tech Tips
The sodium inside the exhaust valve is safe as long as it remains sealed inside the exhaust valve.
Exhaust valves filled with sodium can be identified by their "NA" identification mark.
Using SST, compress the 8 compression springs and remove the 8 valve spring retainer locks.
Remove the 8 valve spring retainers, 8 compression springs and 8 exhaust valves from the cylinder head sub-assembly.
Tech Tips
Arrange the removed parts in such a way that they can be reinstalled to their original locations.
REMOVE VALVE STEM OIL SEAL
Using needle-nose pliers, remove the 16 valve stem oil seals.
REMOVE VALVE SPRING SEAT
Using compressed air and a Magnet Hand, remove the 16 valve spring seats by blowing air onto them.
REMOVE NO. 1 STRAIGHT SCREW PLUG
Note
If coolant leaks from a No. 1 straight screw plug or the plug is corroded, replace it.
Using a 14 mm hexagon socket wrench, remove the 6 No. 1 straight screw plugs and 6 gaskets.
REMOVE STUD BOLT
Note
If a stud bolt is deformed or its threads are damaged, replace it.
Using E8 and E10 "TORX" socket wrenches, remove the 9 stud bolts.
DISPOSE OF EXHAUST VALVE
CAUTION:
The exhaust valve is filled with sodium. Sodium is a strong alkali which can produce a dangerous chemical reaction. Be very careful when handling and disposing of it.
Do not intentionally expose the sodium in exhaust valve. If sodium enters your eyes, vision loss may occur. If sodium contacts your skin, burns may occur. If a fire occurs due to a chemical reaction with sodium, burns may occur.
If the sodium in the exhaust valve is exposed, perform all necessary preparations to safely remove and dispose of the sodium.
When removing a damaged exhaust valve, always wear rubber gloves and safety glasses.
Do not intentionality cut or break open the exhaust valve to remove the sodium.
Tech Tips
The sodium inside the exhaust valve is safe as long as it remains sealed inside the exhaust valve.
Exhaust valves filled with sodium can be identified by their "NA" identification mark.
Waste disposal preparation
CAUTION:
Observe the following precautions when performing the disposal procedure.
Have a suitable fire extinguisher close by.
Wear safety glasses.
Wear rubber gloves.
Waste disposal
Remove the damaged exhaust valve from the cylinder head sub-assembly.
Prepare a large container, such as a bucket or oil can, filled with 10 liter (10.6 US qts, 8.8 Imp. qts) or more of water and place it in a well ventilated area.
Using pliers or a large pair of tweezers, hold the damaged exhaust valve upright and submerge it into the water.
CAUTION:
Make sure to fully submerge the damaged exhaust valve in water.
Do not allow any sparks or other flames near the container as hydrogen gas is generated by the chemical reaction.
Stay at least 2 m away from the receptacle as a strong chemical reaction occurs.
