409 steering idler repair

[John Rolfs]

My inquiry is for the bush, pin and oil seal dimensions to overhaul my steering idler. The 409 has PAS with the ZF steering box as on later models.
I would suppose that they are Imperial measures and that the bushes are Oilite sintered bronze type. I will grease pack on reassembly and use a two lip seal to help keep out the grime.
All advice on removal and dismantling appreciated.
