4. Grinding the valve seat
Grinding in valve seats using the valve spindle with grinding paste must be avoided
as a matter of principle!
Therefore, always use the valve grinding device 94291 for grinding in the valve
seats in the following cases:
− When new or reconditioned valve spindles are fitted.
− When the seat surface on the valve seat is badly damaged (impacts, corro-
sion scars).
