The OEM seals are designed to keep water out, not oil in, so not surprising some mods were necessary. Struggled a bit to fully understand everything you were doing from the description alone. Any chance of some pictures if you ever get it stripped down again?I initially envisaged a thick walled internal rubber seal , but it turns out it only has a 2mm space to fill, so won't be making a nylon o-ring mount, and just fitting a row of o-rings. I have ordered some 2mm thick o-rings from China, but previous experience has shown the ones that arrive are on the light side of the specs, so it could mean I'll be re-ordering in 2.5mm. Nothing to do on the lathe yet, I guess you could make a spacer and use less o-rings, I think a continuous row of o-rings simulates the original 17mm long seal though.
The major modification for changing to oil was the fitting of a drain bung to one side of the jacking point on the tube, and drilling a smaller breather hole higher up with a dust flap. I have just some tape so far, maybe one day glue on something better or run a smaller breather hose up to a dry place.
The trickiest part is the cutting of a thread into the (not so thick) axle tube for the bung/filling point.
