Full Description: *

When REO machines/drills the side bolt mains, a small lip is formed when the edge of a proud core vent screen is left after machining. This condition doesn't cause any functional problems with the engine but it may reduce the machine plants tool life. The condition is caused by not having the vent/ejector rod locations centered to the drilled holes. For future design, when new coreboxes are made, make sure that the vent screens/ejector rods are centered to the drilled holes. Attachment shows S & T core only. Need to look at all cores where machined holes are drilled.
