(Urgent) Bevel box/diff cap weeping - please help

warp9.9 said:

If it were me I would pop the bevel box out and see if you have any oil in the swing frame tube? I ma not sure if the breather has any type filter in it to catch debris or oil if it was laid on the shelf full for a while that might have soaked up oil but it does not sound like it since you said you road it for a while. I have seen the seal in the bevel box go and oil travel up into the swing frame tube I also have seen the rear seal on the torsional damper go and get filled with engine oil but that was prior to the rear bearing in it being sealed and filled with grease Pre roadster. I have like I said rotated the gear while filling it and with he oil being thick it coated everything up top and after I got done and closed her up she was over filled which came out the breather I made a note to never rotate the wheel while draining and filling the bevel box and never had the problem again. I usually change mine every oil change or ever other oil change or you'll have a partial liter bottle on the shelf for years

Thanks for all your help - I'll check the levels and refill it once more if needs be, then I'll have a go at opening her up if all else fails

Probably an obvious thing but anyhow have you checked the oil level after riding and the oil is hot with the bike sitting level if oil runs out over the filler plug threads just put something to catch the oil and walk away and let it find the correct level ,if you live in a cold area the thick gearbox oil can cling onto the gears above the oil filler plug and when hot mix in and give an overfull symptom ,bearing in mind how little the oil capacity of the unit is a few Mils can make a difference ,I overfilled mine once by just putting the filler plug in with a slight bit coming out thinking a little extra might help and it spat it out the breather after a few Klms,

I do live in an incredibly cold area, but the bike was cold when I changed the oil. Perhaps I'll just clean the box now and keep an eye on it/levels before I try refilling?
