Anyone know the specs of the 2008+ inner primary bearing or does anyone know what the Timken bearing equivalent is?

 

Still looking for a better IPB I see. After they switched to the larger shafts of the 2008's they all decided it wasn't worth it. I wish they, some1, would make the one piece bearing and seal for the 2008 and newer.


as you already know I came up with Nota
GL

 

No, I have not come up with anything. I have called Baker and All-***** and talked to them. Nothing. I reiterated the issue that we all seem to have with the IPB and race. All-***** said they would talk to their research to see if/what they could come with.

I have not found the specs to the IPB to see if timken has a cross reference with it.

Maybe I am going to far with this, maybe just replace it and replace the tensioner would fix this. I just think after 35k miles and IPB replaced once and a second one making noise and soon to be replaced is a sign of poor design, bad quality, or something. Just would like to get it fixed and not have to worry about it again for the life of the bike.

 

may i suggest. if you buy 1 new bearing and race, from harley.go to bearing shop and have them try to match-up the size of it .and let us know what you came -up with.mrfuji

 

Just curious...what kind of noise does it make as it starts to fail?

 

In the old days around here we would go to King Bearing and they would cross reference and find ya one....And it would usually be a timkin.

 

You could mic everything and order one out of a bearing spec book.

 

The new OEM race is case hardened and is a significant improvement over the original item fitted at the factory, while they will not admit it, just looking at them shows they are a lot different now.

 

If you want to save IPBs , you should, ditch the auto primary tensioner, 07 and older bikes had the spec of over 1/2" free play in the chain cold, now it is nothing.
So the compensator issues, and the IPB issues I believe are caused by the auto tensioner, because of the longer trans shaft, and crappy trap door bearings.
Look at the trap door bearings in a 5 speed, and look at the trap door bearings in a 6 speed, the 5 speed bearings are almost 2 times wider, so yes they are going eat all kinds of things.
I will stick with a 5 speed thank you.

 

I believe...

Some body would have one for sale by now, if they could put a 300% markup on it like everyone has done for the earlier models...

I looked up the earlier bearing a while back, and when asking a particular vendor of this bearing about the price of $35 compared to what I could find all over the internet for 8-12 bucks, I was told they actually machine the bearing before offering it for sale. Uhh-huh, not calling anyone a liar, but I'd like to see that setup...
