I have a Triumph Part # - how do I find out what it is?

[curiousmike]

I've gone to BikeBandit.com, and it's no help.

When I bought my '98 Trophy, it came with a o-ring/gasket ... but I don't know what it's for.
I *suspect* it's for the oil leak I have around the output shaft / countersprocket.

The part # is "700T3600099" -- it's a 3.5" diameter o-ring AND a smaller 0.5" o-ring in the same "TRIUMPH Genuine Parts" bag.

Any idea how to find out what they're for?

ronayers.com has this neat feature - part number lookup - I am not sure though if they have Triumph DB

never mind - they have no triumph

If I had to guess, I would say it is the o-rings that come with a new Triumph oil filter.  The smaller one goes on the shaft, the larger one around the base.

Does it look like this?

Here's an idea; Call a Triumph dealer's parts dept?

Don't go getting all smart on me.    

Rince - that's exactly it.  And I have the filter.  
Thanks!
