Solution: Replace the existing trunnion with the redesigned trunnion, P/N 14154 rev. 4 available at the Conroe facility. This part has been reworked with deeper, full penetration welds. In addition, the two-pin connection has been replaced with a more suitable press-fit connection. Note: This new trunion is fully compatible with the rest of the parts for the HS-2000 Centrifuge. 2 www.nov.com/brandt
