Fig. 1 Valve dimensions
Note: Intake and exhaust valves must not be reworked. Only lapping 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 while this is done. Then throw the valves into a bucket of water (not more than ten at a time). Step back immediately because a
chemical reaction occurs when the sodium filling burns.
^
After this treatment the valves can be disposed of in the normal way.
