2 | Clean removed valves and remove any oil carbon adhering to the valves | ||
| Inspect | ||
3 | Inspect whether valves can be re-used | - The valve stem ends must not have any surface damage, - the valve keyways must not be worn, - the chrome layer on the valve stems must be undamaged and complete. Scorched valves must be replaced. | |
4 | Inspect concentricity and dimensional tolerance of valves | Inspection and machining dimensions of valves It is not permitted to straighten a valve. | |
Micrometer | |||
Valve grinding machine Minor variations in concentricity can be corrected by re-grinding the valve seat on the valve grinding machine. | |||

Grinding | |||
5 | Clamp valve in the valve grinding machine as close as possible behind the valve disk (Fig. A) | To avoid vibrations. | |
6 | Grind valve | - Set the necessary grinding angle at the valve grinding machine. - Move valve with a slow infeed toward the grinding wheel until it comes into contact with the seat surface of the valve. - Continue grinding with a small infeed until the valve seat is clean around its entire circumference. | |
After the operation measure dimension "H"; this must not be less than the specification. | |||
Inlet valve seat surface machining dimension (H) related to valve seat surface diameter (G) | |||
Exhaust valve seat surface machining dimension (H) related to valve seat surface diameter (G) | |||
- Face-grind the valve stem end with the prism mount of the valve grinding machine (Fig. B). | |||
After the operation measure dimension "C"; this must not be less than the specification. | |||
