Engine Blows-up

I had a "Brand New" 05 (3 Hours) with a similiar failure last year. Husaberg was not overly helpful and the end user (my customer) none too happy.

HMS has parts for 01-03 bikes, mostly, as I managed to get my "new" rocker cover from him.

don't speak to soon. good luck with it though.

So I have created an add in the classifieds, selling the bike as is. Not sure what it's worth with a busted engine so just make an offer.
 
i'm really sorry to hear that fella. i hope you have a stroke of luck along the line. if you bring all the new parts to dez's on march the 6th i'll build it for you - free. dez lives in LV.

The primary nut was a common thing over here in Oz especially for the motard guys racing, 1 guy did pretty major damage when the same thing happened, but let the rest of us know and a fair few found that nut a bit loose, so we all pulled the sides off loctited and wrenched back up with no problems, I'm pretty sure I posted something about it but it would have been a couple of years ago now. Sorry to hear about the problem.
 
Acyr, I can't believe you really want to do that. I am sure you can find the parts if you look around, but you also mention that you want it professionally done, and that's what I really don't understand. Maybe you're a very busy guy and you don't want to mess around with technical details, in which case I would understand why you'd want to stay away from Husaberg in the future, but if you looked at it a little closer you might be able to do it yourself.

As for the left side case, are you sure you cannot import one from Europe or even look for a parter?

Used parts does not seem to be that easy to get, not sure where else to look except for this site, ebay or a dealer. So I will have to spend probably a minimum of $2.5k on new parts. If I can find the time to rebuild it myself (I'm not even sure how many hours it takes when you have all the tools and the know-how), I could still mess it-up and have spent that money all for nothing.

If I want to make sure it's done properly, then I'll have to spend about $4k to have it done professionaly. Can't justify that amount knowing what the bike is worth even if it's in great shape.

So easy decision, either I cut my loss now and sell the thing as-is. Or it becomes a long term pet project that I attemp to rebuild with different used parts as they become availlable.

The checking and retorque of the primary drive nut is something that is part of regular maintenance at my shop.Esp on the 550 and 650 engine.
It is usually very apparent as a loud clicking noise as the nut backs off.
This is also an issue with the YZ450 engine.
We have never witnessed a gear that has shatterd,always was caught before.
My theory is that the torgue reation on the nut on quick crank deceleration is the root cause for this,and is most often seen on motard and road racing bikes.

You guys make me nervous!!! I just bough this 650 2004. How can I check the torque on this primary drive nut???? Where is it??? I have the repair manual on my computer, which section/page talk about this drive nut torquing?

I want the "Long Love Affair with my Husaberg" not the oh F... I am F...!!!

Thanks.

this photo shows the gear you need to check in the bottom right corner - half concealed.

please read through things before posting questions. the torque figure is discussed.

remove tank and seat
remove exhaust complete
remove the kickstart and gearlever.
drop water at waterpump.
remove waterpump cover then the clip and the fan. now the locating pin.
place bike hard overr on iot's right side.
unbolt the sidecover and remove gently trying to save the gasket.
lock the primary gear and the clutch gear with a big flat bladded screwdriver or with the factory tool.

i suggest yoiu go straight ahead and undo the nut, put loctite on the thread and then retorque it.

reverse the rebuild process.
careful attention to topping up the water coolant.

regards

RE: picture fordipsey

Ok so this is the list of parts that I think I will need:

1-left engine case 800.30.000.044 engine case for the 450/501/550/650 the same ? Also seems like I can't get just 1 side?
1-woodruffkey 6946 005
1-Primary gear 800.32.000.029
1-Outer Clutch Hub 800.32.000.078
1-clutch cover cpl 800.30.001.044
1-gasket clutch cover 800.30.025.000
1-water pump gasket cover 800.35.053.000
1-Cylinder Head gasket
2-intake valve 590.36.030.000
2-exhaust vavle 590.36.031.000
4-vavle stem seal 590.36.027.000

Could the vavles have damaged the piston? Should I also be replacing the timing chain? Any other parts or tools that I must have?

1-timing chain 810.36.013.000
1-timing chain link 800.36.013.050
 
RE: picture fordipsey

just accept that upon stripping, you will probably need to top up your order. most people do it if they can't wait till it's all stripped. you need to be patient.

you may have damagaed other things but it's reasonable to hope that you possibly haven't.
you'll need two inlets and two exhausts because IF you need any of a type-you'll need both.
timing chain may be good - some would change for piece of mind!
piston, like the valves, needs to be checked when you've removed the head.

you really can't have your cake and eat it. you want all the answers BEFORE you've stripped the engine. this isn't possible.

RE: Re: RE: picture fordipsey

Here is a picture of the crankshaft keyhole, do you think this can be fixed by having it rewelded and machined?
