Valve Seats and Valve, Grinding

For valve sealing angles, refer to Technical
Data page 27.
NOTICE! Spare part valve seats are already
machined, and do not need further grinding.
Valve seat, grinding
1 Before the valve seats are ground, the valve
guides must be checked and changed if wear tol-
erances have been exceeded.
2 When grinding valve seats, do not remove an
unnecessary amount of material; only remove
enough material to give the valve seat the correct
shape and a good mating surface.

3 Grind new seats down so far that the dimension
between the cylinder head plane and the valve
disc surface, is in accordance with specifications;
refer also to Technical Data page 27.
4 Check the valve seat angle with a valve seat
gauge, once the seat mating surface has been
coated with a thin layer of marker dye.
