I know I'm being a bit lazy, but I need an oilseal for the front hub on my 1962 traveller, and don't really want to strip the hub off to size it up. Going in and out of my local bearing supplier a lot means I could pick one up tomorrow with the size. From what I recall it was 2.25" o/d 3/8" thick, but inside dia I can't remember. HELP PLEASE!!!

You would need to measure the stub axle on a king-pin assembly. It's dark and raining - and I'm not going out to do that tonight!

OD is 2.125", ID is 1.375" and thickness is 0.3125" (0.375" is probably OK, but it would stick out 1/16").
Edit 19 Jul 2017: Use the correct width seal of 5/16". A 3/8" wide seal could work its way out of the hub, as the closed end of the seal is the bit that will stick out, and it is the closed end that provides most of the strength for the interference fit between the seal and hub bore. This is from an experience of a similar (non-Minor) occurrence where an over-width oil seal, fitted in the same way, worked its way out of a rear hub housing, and caused a severe oil leak. Fitting the correct seal resulted in no problems in the last 2 years or so.
