Hi,
Shortly I think I will have to take the engine out of my Ulsteroid to try to fix the oil leaks I have been ignoring.
Whilst the 3-speed gearbox is out I'd like to improve the oil-tightness around the input shaft and some while ago I did buy a modern lip seal from one of the cherished suppliers which I naively thought could be fitted without any machining. The reason I thought this was that there was some info on the Dorset Austin Seven Club site which read:-
“A simple and cheap way to overcome this problem is, firstly, to renew the bearing and then insert a modern oil seal in the nose piece between the input bearing housing and the roller bearing. This stops oil from reaching the worn quick thread. There are 2 types of seal: either Payen NA080 or Payen NA092 will do the job and they are simply a press fit in the housing, It is a good idea to grease the new bearing as hopefully no oil should now reach it”.
Anyway, the seal I have is marked SC 1-1/8 1-7/8 ¼
So, does anyone know if this is the correct seal and if the gearbox front cover / nose piece which contains the quick thread needs to be machined to fit it?
At the same time I'd also like to do something about the baulking I often experience when changing from 2nd to top gear. Any suggestions what may be causing this and what could potentially be done to improve matters.
Many thanks,
John.
