Abstract
An example method of accessing a valve assembly of a turbomachine includes accessing a check valve of the valve assembly from a first position that is radially outside a flow path through the turbomachine. The method accessing a shut off valve of the valve assembly from a second position that is radially outside the flow path. The check valve and the shut off valve are configured to influence communication of lubricant along a lubricant communication path that extends between a location radially outboard the flow path and a location radially inboard the flow path. The first position is the same as the second position in some examples.
