How many Klms?

Hi all,
I was wondering if somebody could verify how many kilometres I think my bike may have done and some idea what major engine work may be due ie bearings, piston etc (I took the speedo off as soon as I got it).
I'm guessing about 8000 klms of weekend trail riding, does the following info tally with this guess in other people's experience?
FE501 bought new Jan 02
Just replaced original sprockets and chain (chain so-so but teeth missing on rear sprocket).
Replaced cam follower bearings twice.
Replaced stator/rotor.
Just replaced cam chain (tensioner maxed out)
Valves adjusted and oil changed regularly.

My 650 has done 7500 road kms that equals about 120-130 hours.

Watch the rocker rollers, and cam chain.

Thanks Lloyd, do you have any idea how many klms to expect out of these motors? Or just wait till something starts rattling bad then rebuild it. I've had three good years so far but am wondering what condition all those whirring bits are in.

Hi,

I wouldn´t dismantle a whole engine without a reason.
As Supermoto_Husaberg said you should check your cam and bearings by replacing the
valve cover.
MY opinion is that you hear and maybe feel if something is wrong with your engine.
It´s almost impossible to say after how many km´s or hours each eninge has to be overhauled. It depends on how you use and maintain your engine. Some people ride hard others not, change oil a lot, check valve clearances, clean air filter... etc.

Maybe some day your engine need more oil or it produces little blue clouds,
then you know it´s time to check your engine.

Jan 02, shouldn't that be a single bearing counter balancer?
What happens if that bearing fails?

Hi,

yes, Jan 02, the engine surely got single bearing.
I don´t know what will happen - I think the engine will stop
immediately.
I have also got the single bearing counter balancer and 100 hrs of also riding and no problems.
A friend of mine has got a FC 550 (2002) which single bearing counter balancer failed after 5 hrs.
The engine just stopped quickly, our dealer made everthing as guarantee. ;-)
No other damages were caused of the failed bearings....

I´m not sure if it makes any sense to dismantle the eninge only for just having a look to
the counter balancer bearing...?

But as I said before: It´s not easy to make a decision if it is necessary or not to replace all
the bearings and other stuff.
Every engine has got other conditions.

Just a small question in between; my fx470e is from march 2002. Would this also be the single bearing counterbalancer? The 470 is a bit more revvy I think, is this of influence of the balancer also?
Regards.

Hi Maichusa,

I think you have also the single bearing counter balancer.
What I experienced is that the smaller engines bascically have less
problems than engine with a bigger bore (550 and 650).

The counter balancer bearing has no effects on your higher revs.
It has to do with the stroke of the engine. The 400 and 470 has a low stroke
that supports higher revs.

Or did you ask if your higher revs have a negative influence on your
counter balancer? That´s normal, I think. Higher revs cause always
more wear in your engine...

greetings

PS: Will you ride the wintercross in Groesbeek on sunday?
Maybe we meet each other. Maybe you could write me an email...
I´m not really well informed right now. I don´t know if I need
the "startbewijs" for 2005 or if it is possible to ride with the 2004 one.

My 02 FX470E had a single row bearing in it and an aluminum timing gear. I had a catastrophic failure of my counter balancer driver shaft bearing. Not the single row counter balancer! At 1200 miles (USA) = 1931.21 Kilometers. I’m not sure on the hours? This failure could have been much worse! My counter balancer had a ball bearing jammed between the case and balancers weight. If I had been on the pipe. It would have taken the bottom of the case out. Before the bearing failure. I started finding ferrous metal in my oil screen and there was a noticeable change in the whirling sound of my motor!! I was in a hurry to get the bike back together for a club ride. So I only replaced, the counter shaft driver bearing SKF- 61905-2RS1, cam bearing's SKF 6201/C4 2ea, crank main bearing's SKF 6206/C4 2ea crank seals, oil pump reed valve, (steel) timing gear / chain and the rocker arms. If I had more time and money, I would have like to replace the piston and the connecting rod assembly. They looked great though, it will get it next time!
The counter balancer with the double row bearing was very pricey! I pulled the new balancer off the crank and bearing assemblies came out of the weight and gear assembly (I carefully pressed them back together!) But the only differences I seen between the new balancer and the old one. Was that new balancer had two bearing and a very thin spacer shim. The bearings looked to be the same on both balancers? They just stuck two bearings and a thinner spacer shim in the new one? I feel that the old balancer could be repaired or upgraded to double bearings easily. I've been in contact with my dealer inquiring on the availability of the bearing's and shim? If we could get these three pieces? Maintenance of the counter balancer would be a lot cheaper.

Hi Marlin,

unfortunately the bearings are not just doubled up single bearings. If you were to try the job yourself there would be quite a lot of machining to do, even on the old counter balance weight.

In addition, the very thin shims are there for more accurate setting of the crankshaft end float upon reassambly, rather than simple spacers.

Both bearings and shims should be available separately for maintenance work, it's just that if you have an early 02 or an 01 with the first revision of the weight, it does need to be updated to fit the bearings (or machined as necessary).

Cheers,
Simon

What do you feel that’s different? The OD of the outside bearing race? I still have the old balancer and when the two bearing came out of the new balancer, I set them over the old balancer the seemed to be the same size. I didn't mic them though. The bore for the bearing's on both balancers were straight bores all the way through the balancer and they were a press fit. As for the shim they came up with it for the new piece I don't see why they could come up with it for an up grade, I feel the same way about the bearing's in the new balancer? It would have to be a husaberg wants the sale of the pieces. Maybe as a up grade kit or maintenance kit?
Thank you for your time Simon

Hello Marlin,

hmmm, interesting, you may have found a slight anomaly there.

The original c/b weights had a stop at the rear. Essentially a plate with a smaller diameter bore than for the actually bearing carrier part. The bearing would be pressed up to it and then a circlip fitted to the other side to prevent movement. A spacer was then fitted to the rear of the bearing that was approximately the same width as the stop on the c/b weight.

Hope I'm making sense here ?????

One of the main differences with the upgrade was that there was a uniform bore all the way through the c/b.

As for the bearings themselves, the difference is in the individual width of the bearings - double up the old single version and it is wider than the 2 upgraded double versions.

Your measurements are correct in that the total width for the double bearing version c/b is the same as for the width of the c/b with single bearing. The only width difference here being that of the single bearing at the inner race - it being thinner on its own.

As for your situation, I'm interested to know if your single bearing is the same width as one of the double ones because if it is, it means you have received half an upgrade from the factory (the double bearing starting to appear on bikes out of the factory mid MY2002 production).

Cheers,
Simon
