Steering shaft leak at steering wheel base, Jinma 285.
I replaced what Jinma calls a seal below the steering wheel.
I don’t know how they call this a seal since it not tight at all. It is just for a contact for the horn. The steering housing is full almost to the top of the shaft and leaks out of the top of the steering housing when running. I can’t figure out why oil is in there. Anyone have any ideas about this?
Thanks redjetster

Do you have a parts book? If not, look at the diagram on this page:

The input shaft seal in part #17 is leaking and forcing oil up the outer tube part #6. The leak is actually at the bottom of the column. There is no parts breakdown for the steering gear box. To fix it your only option is to take it apart and take to seal to a bearing supply place to see if they can measure it for fitment.
Personally, I would buy an entirely new gearbox as there may be other parts worn. Then once the new box is on and working, I would take the old one apart to see if it is worth fixing for a spare to have on hand.
