Tip: Use grease to hold the cotters on the valve stem when removing the spring compressor.
5. After installing all the valves, make sure that the cylinder head is stable, take a hammer and, through an intermediate block of wood, lightly tap on the end of the rod of each valve. This will allow the elements to take a stable position.
6. Install the camshaft (s), hydraulic tappets and valve levers (whichever is applicable), as described in chapter 2A.
7. Install all other elements, working in the reverse order of removal. Install new seals or gaskets if necessary.
