Fig. 1 Valve dimensions
Notes: Intake and exhaust valves must not be reworked. Only grinding - in is permitted.
CAUTION:
^
Worn exhaust valves with sodium filling must not be disposed of until they have been treated as follows:
^
The valves must be sawn into two sections with a metal saw at a point between the center of the shaft and the valve head. They must not come into
contact with water when this is done.
^
Throw the valves into a bucket of water (not more than ten at time). Then step back because a chemical reaction occurs when the sodium filling
burns. After this treatment the valves can be disposed of in the normal way.
