Task Description
01-7162 Cylinder Head Reconditioning
Preparatory operations:
Cylinder head removed (01-6110).
Valves removed (05-4102).
Injection nozzle removed (07-6812).
Check cylinder head support surface for flatness and indentations with straight-edge or bridge meter.
Cylinder heads with worn support surfaces can be reconditoned with a grinding machine.
Stop reconditioning as soon as the specified surface is reached, refer here to the Tolerance and Wear Limits List.
After reconditioning the cylinder head partitions, check
− Valve recession check, see Valve Seat Insert Machining (05-4532).
− Check nozzle protrusion, correct with nozzle plate if necessary.
See Tolerance and Wear Limits List for limit values (01-7162).
In order to achieve the prescribed roughness depth when grinding, we recommend that you observe the following

Advance
Cutting speed
The specified cutting speed is reached at a segment grinding wheel diameter of 370 mm With another diameter
(depending on machine type) the speed should be altered so that

Note
If the advance is smaller, or manual, there is a considerable effect on the grinding pattern and no guarantee that a
