Remove the injector holders
AR07.03-B-6831A
3
Remove the cap (1) from the exhaust valve foot (10)
Installation: The valve foot and the inside of the cap, must be clean and dry.
4
Measure the distance between the faces of the valves and the bottom face of the head
AR05.30-B-4100-01A
If the measurement obtained is not within the recommended values, rework and/or replace the valve and/or seat.

6
Press the valve spring retainer (3) down with the valve assembly tool (11) and remove the valve keepers (2)
Installation: Perfectly fit the valve keepers (2) in the groove of the valve stem (9/ 10) and check the correct seating of the spring retainer (3) on the spring (4/5) and on the valve keepers (2).
7
Relieve the load on the device (11) and remove the spring retainer (3), the spring (4/5) and the spring spacer washer (6)
8
Remove the valve stem seal (7) from the cylinder head (8).
AR05.30-B-3510A
Replace the seal, whenever it is and/or the valve is removed.
9
Rotate the cylinder head and remove the valve (9/10)
Mark the valves and their respective seats.
Installation: Oil the valve stem with engine oil and observe the marking.
Check
10
Check the valve guide wear
AR05.30-B-3731B
If a fault occurs, replace the valve guide.

Check the valve (9/10) for dimensions and condition
Inspection and machining dimensions of valves
AR05.30-B-4202-01A
Grind valves.
AR05.30-B-4202C
Replace the valves when they show signs of wear at the keyway grooves, damage at the end and the chrome layer of the stem, and burned seats.
If necessary, rework the valve.
12
Check the condition of the valve seat
AR05.30-B-4511A
.
AR05.30-B-3831A
In case of slight deformation of the seat surface, it is possible to rework the seat, provided the distance from the valve to the head, after reworking, is greater than or equal to the allowable minimum value.
If necessary, rework the valve.
