Standard parts (brassring: see figure) will be changed; the disposal is suggesting to assume that the clampingset area was flooded with bore emulsion --> probably there are used tools without atransfer tube.The chuck head does not show any wear out and can be continued to use.Further findingsRevision 99903671 / 5Page 5 of 9
