Refacing | |||
1 | Clean the valves (1), eliminate the oil carbon residue. | ||
2 | Secure the valve (1) in the grinder chuck (2) as close as possible to the valve head. | Vibration is avoided this way. | |
3 | Set the angle on the grinder scale (2). | Intake valve angle “A”. | |
Exhaust valve angle “A”. | |||
4 | Through the grinder feed control (2), slowly bring the valve (1) towards the emery wheel. | ||
5 | Operate the feed and reface the valve seat until it is perfectly clean around all its circumference. | After this work step, check all the checking values. | |
Exhaust valve seating diameter (B). | |||
Intake valve seating diameter (B). | |||
Machining measurement (H) of the intake valve seating surface. | |||
Machining measurement (H) of the exhaust valve seating surface. | |||
Intake valve diameter (G). | |||
Exhaust valve diameter (G). | |||
Width (F) of the intake and exhaust valves. | |||
Maximum eccentricity of the valve seating face in relation to the stem. | |||
| |||
| |||
6 | Lift the valve (1) off the grinding machine (2). | ||
7 | Grinding the end of the valve stem utilizing the prismatic support of the grinder. | Check the length checking values. |
