Aftermarker A4VG Swashplates

This example shows more swashplates for A4VG pumps. The casting is of an extremely 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.

Here you can see such a swashplate after 2 hours of operation - 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).
