This example shows more swashplates for A4VG pumps. The casting is of a
very low quality, and presents a notorious hairlike pattern on the back
of the swashplate - the sign of bad bonding between the layers of
melted metal. Bad casting, combined with inadequate heat treatment
resulted in a very fragile part.
you can see such a swashplate after 2 hours of work - it already started
to crack, and the last four pictures show how such a part can
cause a major failure (again - after but a couple of hours of service).
