Good suggestion Dan but unfortunately we would have to specify and then have manufactured the right size or you would have to modify the crank cases. The ones available on the open market are all of an incorrect size for the crank.
The bearings you are refering to are, I believe, commonly called toroidal roller bearings some of which are designed to be self aligning. They do accomodate more axial misalignment in terms of degrees of the arc but IIRC they also have a reduced max velocity and load compared to the good old roller bearings.
I believe Dale has also done some significant research in this area :wink:
As for the comment by someone that the end float is taken out by the DCR mods - is that wise?

Hi Gix
i`m with you were D.C.R. is concerned, nothing but great service. Couple of weeks ago i had a problem with the trusty Berg(very minor as it turned out to be, me panicing over nowt) one call to Dave, i explained the problem and that i was racing the next morning. With that he offered me a new bike to race on the next day. GREAT SERVIVE. Dave is a genuine bloke and does a great job as an importer.

Hi Dan,
Most quality off the shelf "cylindrical bearings" of now, albeit slight (.00010" +/-) are indeed crowned.
Yes, both Ron and the Jorgensen family are friends. The late Toby Jorgensen (Nephew of Alex) was the very first to put a Husaberg in a mile main event.
Kind Regards,

hello gents,
Interesting topic. I love the technical ones...
SKF, I just noticed, has upgraded there web page in a few ways. I like the new changes I have noticed (since being there last). This place has tons of info for us all to peruse. A few links regarding this post:
Toroidal Bearings
Click on "Product Tables" on the right, then a window will pop up. Click on "cylindrical and tapered bore"
Bearings Front Page
The web site does leave a bit to be desired in regards to ease of use, but it is awesome once you are used to it.
WHAT SIZE IS THE MAIN BEARING???
Does anyone know this offhand?
I have a feeling that these bearings might not work because of size availability. AND, I know for a fact from trying to get "existing" but not stocked bearings from SKF, that getting custom bearings is practically impossible. This is why the cam bearings are a standard issue 6202 (or 6201, 6203, something like that). So, unless one would want to machine, then this may not be a possibility.

regarding the main bearing failures that this topic started from.i have not heard of any occurring in north america on any bikes years 2003 and newer .not from of my customers or from any other customers.i have not received any such notices from our importer either regarding warranty procedures.i would hope there is no bearing issues in the future.lets be careful not make an issue out of what seems to me a non-issue.i have not been hearing about lots of failures from Vor or KTM either as they use the same bearing.Dave Clark would need little elves working for free to be able to perform such extensive mods and still make money assuming he does make money. not to challenge anyone but is there real proof that such mods are being performed?pictures,invoices,bearing numbers.until i see something more convincing i am going back to the garden and planting roses.

Hi Dan,
Said failures appear primarily isolated to that regarding European "high speed" Motard applications. Excessive engine rpm coupled with traction beyond belief and consequent case loading would likely account for the majority of failures. I personally have addressed said issue regarding Husaberg dirttrack and road race applications.
In short order:
98% of the Husaberg population need not be concerned.
kind Regards,
Dale

Main bearings size is 62 x 30 x 16 (OD,ID,W). SKF do not do any bearings that size other than standard deep groove ball and plain roller. SKF CARB toroidal bearings allow both angular and axial misalignment, i.e. they can pivot and slide in and out so would probably not work in this application. None the less the SKF site is indeed very useful for info'
DCR certainly replaces the rollers for balls in all re-building work he does, and the new engines that I have bought have had it done. Personally I have found Dave to be very helpful, though I build engines differently than they do at DCR.
Motoxotica
DCR makes money OK, this is a quote from his website "With a growing, enthusiastic dealer network and an improving product, Dave became the world’s top selling importer in 2002 and 2003, selling 426 bikes in 2003."

When you say that you have addressed the bearing issue, what have you done if may ask. I have read all of the other posts concerning mains, if there is nothing to add to what you have already written apologies for dragging it up again. Is alignment your main aim? or do you use non-standard bearings?

Hi Ben,
Redundant engine information, however, regarding the chassis:
For tarmac I have used a twin spar design (Honda Hawk, etc.) in order to eliminate speed induced crankcase flex.
Our dirttrack chassis does flex, however, not through the engine as does the OEM.
The above comments are with regard to loads induced via high speed turning as opposed to acceleration.
Best Regards,
Dale

From one Dale to another, Thank You.
I have roughly 30 hours on my 2004 FE550E, and it just seems to keep running better and better.
My friend's 20 year old son who we have been riding with since he a little guy, rode his Dad's new 02 520, and then my 04 husaberg, said "he was sold on the Husaberg". And that he would be buying one in the near future.

Perhaps not evidence as such, but I can definately vouch for mine being done as I was there whilst it was.Motoxotica said:
I have also personally seen about 7 or 8 others being done.
The tech at DCR knows me from the last dealership he worked for and knows I'm a picky b*stard..as he found out when my GSXR went wrong...he now makes a point to show me any parts the he has replaced and explains why..whether I'm paying or not
Hi Dale!
I think the main bearing problem is more complex than that, I don’t think that the flex is the main factor for the failure. Last year Fiorentino left Husaberg half way throe the world championship because of engine failure dew to main bearings!!
And the Husaberg frame was by far the stiffest “and the best performingâ€Â

The first part may just be correctly aligning the main bearings, but I would like more details. As far as removing the counterbalancer, many post-2001 owners are doing this, and a crank rebalance is necessary when it is done. What particular type of bearing they used is also of interest.
missfire said:
This sounds like they are going to lash caps and adjusters, like Dale is utilizing with his aftermarket valves.

I don't know about you guys but something here is smacking of dejavu, or is it ground hog day?
Which, I'm not quite sure but it definitely describes a bit of a circle.
There are indeed very good and reliable solutions to the problem - IF you have it - but, lets face it, those who have found it have spent a lot of money working it out and I'm sure they are willing to do the necessary work for what is, quite probably, a reasonable fee.
All one needs to do is a search of the forum to find lots of good info..........
At the end of the day however, the main bearings aren't really as much of an issue as they're made out to be - yes some do go and by and large they're on 650 motards.
Lets put this one to bed shall we because I'm sure someone has a question about oil that they're itching to ask aren't they :wink:
Cheers,
Simon

I don't agree. I would like more information on the mods done to missfire's Berg, and a report as to the long term durability of the modifications. I want to know any and everything that can possibly improve a bike or motor, and hopefully some of it gets incorporated back into the product line. A wise person or company is one that realizes that others may be able to improve on your mouse trap, and for you or your company to excel/survive it may be wise to obtain these changes for your product. Technical advancements are not a result of complacency.
missfire, any chance you can run an hour meter and keep us informed on the durability of said areas of modification???
Hi PowerFiend!
I cane ask them as to watt bearings they use, I don’t think they are in the business of selling bearings I’m afraid they design and make systems for the deafens industry.
I now that they relocated the bearings in order to balance the left and rite side of the crank, apparently the crank is not supported equally in both sides and this is watt forces the bearings to grind there lip on the rollers, it is not a mater of alignment?
The swivel feet pout the geometry of the rocker arm arc slightly out forcing the valves sideways?

Did I mention or imply complacency? Not even close :wink:
But, this topic is going round in circles, every few months, and a simple search on the forums will tell anybody the information contained within this thread, apart from, of course missfire's engine update. But I wasn't on about that specifically..... :wink:
Every few months I hear about "new fantastic" special bearings someone has found on the market that will solve all our problems and give us three wishes to boot!
Funnily, the euphoria doesn't last too long, hmmmm interesting.
What I also find strange is that I had the very same types of bearings that Husaberg supply in their engines as standard in a car a few years ago that had done over 220,000miles. But hey, maybe, just maybe SKF take out their substandard bearings and ship them all to KTM for incorporation into Husabergs, just so that they can conspire with KTM in the downfall of Husaberg :wink: :wink:
Actually, my comments were more to do with the fact that those who have spent their money and time resolving these problems may not be willing to divulge everything to those that are permanently looking for a free ride, that's all.
I once ran part of a large project based in Chicago for a global company and if I got the 150 IT "gurus" in a room to provide advice, I'd always end up with 150 different ways to do it.......... because everybody knew the answer and how to do it best :roll:

Simon
PowerFiend!
The modes were dun nearly two years ago; the bike has more than 200 hrs on sins the modes!
Simon!
The guys that did the work they never clamed the bearings were not good but wrongly selected, also they did this as a favour sins they like to see me happy!!!
And as I said there not a motorcycle related firm.
To me it is very impressive and interesting the fact that DCR solves the same problem with little effort compeer to watt was dun to my bike! And by the way when I had the problem with my DCR told me there is no problem watt so ever with the main bearings and supply me with the factory specified type and the “correctâ€Â

Say,
Is it possible that DCR is doing this and warranty-ing the cost back to berg? I would see this a a feasible thing to do, since, if by blowing a bearing, it may affect/damage other stuff in the process. I am in doubt of my suggestion, but... If I were Husaberg, and I knew a dealer was selling bikes specifically for Motard racing, where this issue seems to be prevalent, then I might just give them the "green light" to make said upgrades (partially for names sake, I would want my brand to succeed!) to these specific bikes BEFORE they go out the door!
