This is the OEM 1984 to 2006 five speed inner primary bearing, race and seal.

This is a modified 6205 bearing for use in HD inner primaries.  1984 to 2006 five speed applications.

My whole point is that you should keep these bearings around because a standard bearing will not work. Look at the ID they list for the bearing. It's larger than a standard 6205 off the shelf bearing.

I'm out.

I am just crazy happy this shaft OD measures the same as the stock one.
I  lost sleep and had nightmares last night honing out a bearing to fit!   LOL

SOOoooooo i dont know what to tell ya, you can see the dam thin on the shaft

What is the P/N of that bearing and who was the source (Baker, Alls Balls, Drag, V-Twin, etc) ?

[thumper 823]

I have one here from BDl EPB 100
and  a 6205 DU    (maybe from Baker?)
Both fit on the shaft perfectly.
Both have the same Id and OD
This all started out saying  Baker shaft was larger in dia.
In this case, it is not, it is EXACTLY the same as stock five-speed here.
I have now checked every dam thing ten times.
personally Call me done with it.
I think Micro sells these in ceramic, which I will get,  as this BDL unit is already spinning roughly from just last summer's miles and a dyno run.
thanx all-
it was a great exercise in learning some numbers i would not have ever known

What they are trying to get you to understand is if you buy a standard or ceramic 6205 bearing from anywhere they will not fit onto a standard 5 speed mainshaft without having the ID honed to fit. They ones you have from BDL and Baker? have already been honed to fit. Pretty simple to understand but you seem to be thinking people are talking about the shaft which they are not.

Without going on and on and back through all here..
Please believe me I do appreciate the help.
I have now wrestled up 3 ea,  6205 bearings from the drawer of god knows where, as I work on a lot of different stuff here.
All nicely slide on these two Main shafts as they should.
Now perhaps they have been honed..IDK,
but it seems someone said at the onset that the Baker shaft is larger than the standard HD Main S.  ??
In the end here I am going to order a new ceramic 6205.
I will send out a report if it will not fit.
If that is the case I will hone the dam thing out, end of the problem.
This is just not too big a deal to get all stimied over.
It is More EZ to make the ID larger than smaller ......LOL

I think they were telling you so you didn't get caught out thinking there was a problem when a ceramic one didn't fit.
Definitely easy to make it bigger than smaller.

Up all night and up all day makes my mind fuzzzzzzzzy.

OK, OK
We cant very EZ get a 25m bearing over a 25M shaft, that is the essence of the whole length breadth and width here.
For most of us, i have found at least 10 vendors that will sell the odd size up to 25.4  by just entering it in google.
I am not happy under most of us rule, soooooo.......
I emailed Craig @ Micro Blue - But I think he HATES his job as he is always full of short answers.
In other words, he does not care to help unless I draw him a picture.
If all he has to do is enter the number he is great!
  I have yet to find a maker of custom ceramic odd size..
So, I guess it comes dwn to ordering a couple of standard-issue 6205  and making them fit.
I have a question into a real machine shop friend to est how hard this might be.
The answer to follow here.

 Got the Ceramic inner primary bearing yesterday.
Five minutes with a brake cylinder hone and Viola!
I now have a ceramic bearing that "should" last a long time ...
I am going to spend a minute to see if there is any way to get a
remote grease fitting hooked up so a squirt of grease can be given to it once a year.

Hmm, the center hole of that bearing looks too large to go on the shaft. Is that just an optical illusion?

[thumper 823]

It is now an exact fit, it was too small by a 1/2 a hair
