Reworking Cylinder Head

Reworking cylinder head

Check cylinder head for distortion. Check sealing surface for distortion using a straight-edge.
Permissible unevenness of the parting plane: 0.05 mm.

Cylinder heads with distorted sealing surface can be repaired by planing them.
Permissible unevenness after machining: 0.03 mm.




Rework sealing surface of the cylinder head only until a flat surface has been achieved.
Wear dimension: 141.65 mm

Note on machining the sealing surface:
Peak-to-valley height = 0.015 mm
