How about some pictures of the inside?
Does the cam plate turn?Is there a steering box connected, and functioning?
Firstly disconnect the long rods that go through the rear plate to the bellcranks.(this will allow everything else to move hopefully) If not drop the plate off the bottom of the hull that the cam plate is mounted on. With the hull blocked up, and the double bogies removed, can you move the cross tube in it mounting blocks?
These pictures are for an Australian carrier, but they are much the same.
