Valve dimensions
NOTE:
Valves must not be reworked. Only grinding-in (lapping) is permitted.
VALVE DIMENSIONS
| Dimension | Inlet valve | Exhaust valve |
|---|---|---|
| a = diameter mm | 26.8 - 27.0 | 29.8 - 30.0 |
| b = diameter mm | 5.96 - 5.97 | 5.94 - 5.95 |
| c = mm | 104.84 - 105.34 | 103.64 - 104.14 |
| alpha angle (degree) | 45 | 45 |
WARNING:
Worn sodium-cooled exhaust valves must be treated as follows before disposal: Saw the valves into two sections with a metal saw at a point between the center of the valve stem and the valve head. The valves must not come into contact with water when this is done. Then throw the valves into a bucket of water (not more than ten at a time) and 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.
