Machining

1

Clean the valve (1), remove any carbonized oil residues

Do not rework/rectify the seat face of the engine intake valves 457.9. In case of excessive wear or damage, replace them.

2

Properly fasten the valve (1) to the grinder (2)

Keep the valve head as close as possible to the mandrel so as to prevent oscillation/vibration.

3

Adjust the angle to the valve seat face on the grinder scale

Observe the values for intake or exhaust valves.

Valve seat angle on valve

*BE05.30-B-1003-01D

4

By means of the grinder feed, slowly bring the valve seat face (1) closer to the grinding wheel

5

Grind at a slow feed speed until the seating face is perfectly clean and without deformation all over the circumference

After rework, the control values should match the prescribed values.

6

Remove the valve (1) from the grinder mandrel

7

If necessary, grind the stem end top (face in contact with the rocker), with the valve (1) on the prismatic support of the grinder (2)

The length of the valve (C) must remain within the specified limits.
