    MQ 70kva DCA-70 with a JD engine, error code 3673 007 followed by 1569 031 derate condition exists

    The part with a linkage opening a gate at the bottom, sorry I was out last week. JD wants to sell me the turbo. Mine is jammed. I disconnected the linkage and gate is free of moving. This part works with pressure provided by the hose connected to the turbo.
