Thanks for the link on that. After reading through that discussion I'm having cold sweats wondering if the bearing has already been replaced in mine or not. Gonna have to get in there soon!
On a side note, went to the stealership today to pick up my "Badlander" seat for the King. Ended up taking it back cause it looked terrible on the bike. BUT the most annoying thing is that HD sells the seat with no bracket on it. SO the parts guy is like, "Do you need a bracket?" uh yeah that would help dont ya think?
So I have to purchase the bracket, and of course the bracket doesnt come with any mounting hardware etc, so I have to purchase those as well. WHAT A CROC OF SH*T.
Seat with no bracket, bracket with no hardware = an extra $11 dollars in HD's pockets. I know its not much $$$ but it is just idiotic. Not to mention I was next to a guy dressed in so much Harley gear I'm surprised he doesnt crap Harley turds and have to pay for them.

Excellent reading! Hey, I've got a '98 Low Rider. What year(s) did this bad bearing thing happen. My Shovelhead friend told me about this, but he thought it started on the 88ci's.

So not to sound stupid but, is there a way to differentiate between the stock and replacement cam bearing?
Here's a pic
My (weak) understanding is that Torringrton and INA are mfg's and not really styles. It's just that what they selll into the HD market have made us think of them as styles. Not sure if that's important to us or not.

bparsel, Where are you living? Im in B.C. canada & I ordered a whack of parts last fall from "Strictly v twin" in Ontario. the cost on my primary gasket was $35. Im wondering why they are charging you $88??
This is an awesome thread, Im about to do a top end this winter & had no idea that cam bearings might be a problem!
Mine is an 88 vintage 80 CI evo.

You are right on both counts! They are indeed both manufacturers, but the bearings you show are also different styles. In engineering terms the Torrington is called a 'crowded' bearing, the INA is 'caged'.
The explanations are that you can see the rollers in the Torrington run up against each other, as if they are crowded together. In the INA the rollers are held apart from each other by a 'cage'.
In the Torrington at the point where each roller rubs against its neighbour, the two surfaces are running in the opposite direction of each other. This can cause heat built-up and wear, which are less likely in the INA style.
Hope that helps!

hatchetman- I should clarify that I got the "Primary Kit" with all gaskets and seals for $85 from JP Cycles. I'm doing pretty much all of them since I'm going to be in there.
I am glad this thread has turned into some useful info for everyone. I suppose we should really thank Dr. Hess and grbrown! Since all I've done is ask questions and they have the knowledge!
If it doesn't directly affect me, I just collect the data. I have a pretty good memory. Like in this bearing case, my bike has the crowded bearing (thanks for the explaination, Graham), but enough people have complained of an exploded bottom end that I pay attention and pass that along. I was a bit nervous about my bearing also. I replaced my cam and lifters in 06 or so and didn't even think to look at the inner bearing. Then I joined the board here and found there was a problem and got nervous like hatchetman, but was relieved to find that it only started to be a problem in the 90's. The experience of the people on the board here is tremendous.
The internet has really changed the way we do things. Not just with the bikes, but cars and about everything else too. You can find a collection of like minded people and find the answer to a problem in a few minutes that used to take you a month to work out by yourself, if you could.
So, what you are saying GRBROWN, is that the INA should be the better bearing, as the rollers a caged, but apparently is not. Has anyone had a problem with the Torrington?

Jim,
In theory, yes! Many of the bearings in a Harley engine, gearbox, wheels etc are caged balls or rollers. These particular two are normally described as 'needle' bearings, because of their thin rollers.
But sometimes quality of materials and manufacturing processes can triumph over design, which seems to be the case here! Looks like the Torrington is a superior product to INA, even though on paper its design is not the better of the two. Which pretty well exhausts my knowledge of bearings!
