The pre-ST or 851 framed bikes had no seals.

I really appreciate everyones help and input to this matter. I gotta get this solved so I can complete assembly and get her rolling.  So, if no seals were used on the earlier bikes (like mine), should I reinstall that way or not?  Its probably better to have seals, than not.  But problem now is that the lower bearing already has a seal in place.

Other possible option maybe, is to install both seals and not use the "dished" top washer.  Would that be ok?  That layout allows me to thread the lock collar in place.  If I try to use the top seal and "dished" washer, it becomes too thick and I cannot thread the lock collar onto the stem.  Is the stem too short? 

I believe Josh is still out of town, and from his previous post I'm hoping that I didnt get a poorly milled stem.

Are the triples for an 851 framed bike?

If so I'd expect they weren't sized for the extra thickness of the seals and even though the seal is a good idea it may not fit in your bike with that triple.

Supposed to be.  They are the MOD1 line up which is intended for my generation of frames.

I'd ditch the seals and put it together....

but that's me.

Not really an option for me. Lower bearing has already been pressed onto the stem with the seal. Not easy for me to remove.

I understand it isn't easy and doing it without destroying the bearing is nigh on impossible...

but they make new bearings every day.

From the pics you posted it doesn't look like the seal will be effective anyway.

Your bike...your call.

i don't use seals on the early bikes, just the lower plate and upper dish.  and on bikes i do use seals on i don't use the supplied all balls, speedymoto, etc anyway.  they don't fit well.

i'd assemble it original style.  ime the seals on the later ones can be very good at retaining any water that does get in.

 I'm not seeing any seals in the parts book for the 2009 M1100S, just what looks like a cup washer that the call a "seal ring".

That is your seal.  Same type of seal thats been supplied with my new bearings.  2002 and up looks like they use seals.

Does IMA lack in customer service?  Its been several days and I have yet to get a reply from anyone over there.  Italy & North America.  This is upsetting  :(
