You're right Bryan, it's the same seal on both bikes.
I'm not sure if the 400 also used the oil passage through the seal like the CJ but guess it would if it's the same part.
It always amazes me how poor some of these pattern parts are either in accuracy of manufacture or simply not being anything like the correct part.
Of course most sellers don't know or care so just copy the details over from the manufacturer no matter how inaccurate (or badly written).
Dave - thanks, yes this is the first one rebuilt a while ago, now going through the first round of fixing problems and leaks etc. after a bit of running.
Oil leak was a pain being a lot of work for a small part and afterwards nothing really to show for it but can't be avoided.
A couple of final bits to sort / tidy and she should be finished at last (until the next leak / noise / problem pops up of course).
Also replaced the steering head bearings as I wasn't happy with the roller ones I originally used - gone back to original ballbearings for top and now assembly feels much better.
Got the CJ360T rebuilt as well a while ago but only to a more 'lived-in' standard, ready to fill with oil and petrol and see if she runs well.
I'd put it on the backburner while trying to 'quickly' get the XT250 on the road as initially hoped this would be a simple tidy-up.
Of course that changed on closer inspection and has been fully stripped and rebuilt and still needs a few bits sorting but nearly there.
She'd had a really hard life and the PO had repaired / bodged just about every part of the bike and engine so has been a pretty extensive mechanical rebuild.
To be fair I can't complain too much as I happily remember some very interesting 'field repairs' as we called them back in the day which would horrify anyone digging up one of our old bikes now!
Cheers,
Andy
