Fellow Husaberg owners,
I have a (pain in the but) oil leak coming from a weep hole. The weep hole is located at the 9 o'clock position of the water pump. The weep hole is in the side cover ,not the removable water pump cover. No oil inside the water pump. No other leaks on the clutch cover.
Bike is a 2001 FS650 Motard. Any advice on a fix to my problem will be greatly appreciated.
Thanks,
Mackberg

I just did this on my 04 ( don't know how yours is different) After I changed the seal around the water pump shaft, everything has been fine.

ditto vegard

you've been a bully fitting your sidecover at some time (or removing it!) and you now need to buy a $1 oil seal. easy-peasy lemon squeezy!

It wasn't me who removed or refitted it the first tiem luckily
I will take NO accusations

Taffy,
Please explain "Bully fitting? How can removing side cover and replacing cause weep hole leak?

Taffy

the shaft has quite a sharp lip on it and any kind of shoving and pulling does tear out the lips on the seal behind the waterpump.

but you knew that didn't you

Hi all!
Chester at our shop did a lot of work and found that on quite a few 2001 and 2002 clutch covers the weep hole was drilled incorrectly. It was tipped too far inwards and the outer part of the seal actually passed by the edge of the hole allowing oil to pass through the bearing and out the hole without ever encountering the seal. Our cure is to do one of the following;
1) Say to hell with it and epoxy the hole shut. Lazy and effective, but no way to tell if the water seal is failing until it may be too late. It could also foul the oil with coolant.
2) Remove the cover and epoxy the hole completely full, then re drill a smaller hole at a more vertical angle. Carefully cut and file the epoxy at the sealing surface so that the seal clears it upon installation and still makes adequate contact around its perimeter. The ultimate solution but requires craft and workmanship. If I had any talent I’d draw a picture.
3) On my 470, I pulled the bearing/seal assembly out and replaced it with a KTM 450 cam bearing. I don’t have the part # handy, but they’re all the same. It’s a sealed bearing of the same #. I figured that if it could take camshaft punishment then it might take intermediate shaft loads OK as well. Aprox. 20 hours so far and no problems. A tiny bit of Threebond 1104 around the outside of the bearing and no oil leak.
I'm sure that there are other solutions as well, but these have worked out for us so far.
Best wishes, Alan

AlanNMS,

Thanks for the update and techniques to fix. I think in the past, people have just lived with the weep or sealed with a dab of silicon to avoid the mess.

Taff, maybe this should be added to the owners document, I know this topic has been thrown around many times before but this does sound like the best and most effective fix i've heard on this problem. Luckily I have not had the problem mentioned but do know this has been tossed about over the years.

Regards,

Taffy

yes i'll put thast in. i saw a fix for summink last week for a 650. the document is about 400/450 models and as has been said before-you're all welcome to start with it as a baseline and to make it relevant to the 550/650.

Replacing the seal worked for me, but your knowledge and ways to fix, will prove useful to many in the future.
