Swivel Assembly | Oil Seal Retaining Plate... A Little Confused?

I'm just about to reassemble the n/s swivel assembly on my 90, but can't seem to make sense of one aspect. It's an early 90 with the top Railko bush set-up, plus bottom pin and bearing, as opposed to the later twin bearing type...

Upon disassembly of the swivel assembly, I found that there were TWO oil seal retaining plates fitted back-to-back, with no sign of a gasket - with the oil seal located beneath these and at the joint of the swivel housing casing.

The relevant Haynes Manual refers to a "Retaining plate and gasket" and the dedicated Land Rover Manual an "Oil seal plate and washer" - I'm assuming that in this instance the word washer is used to refer to the gasket, but there's no reference made to, or schematic of, a twin oil seal retaining plate set-up.

Would it be that the PO mistakenly reassembled things this way, or is there something I'm missing? I was uber-methodical with the disassembly process, laying all of the components/parts out in order and can confirm, without doubt, that there were TWO retaining plates fitted.

Can anyone shed some light?

Thanks again, in advance.

Thats how the early ones are with two plates, mates 85 was the same

Thanks for the reply.

I did a bit more digging (quite a bit, actually) and you're right, early models do have a twin plate set-up, whilst later models don't - this doesn't seem to be covered in either the Haynes, or genuine LR manuals - even the exploded diagrams are easy to misinterpret. So, it's the oil seal, gasket, then two retaining plates to hang off the back of the swivel ball - before bolting it onto the axle.

Onwards and upwards... should finish this tomorrow, then onto the A-Frame, o/s rear wheel bearings, new shock and fuse box upgrade.. all in time for the MOT!
