Weep hole leaking oil

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

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 :wink:

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,

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.

Welcome to the site.

Doesn't the seal behind the water pump on a 01 FS650 prevent water fom entrering the oil system? What is the purpose of the
'o' ring on the water pup drive shaft and why doesn't it show up on the parts books? I'm sure Taffy knows.

The seal directly behind the impeller seals the cooling system.

The Aux shaft O-ring prevents oil from wicking past said shaft.

So I should replace the shaft "O" ring if I'm getting oil leaking out the wheep hole? Some members suggested I replace the seal, but that didn't sound correct. The "O" ring is the culprit.

Hi MackBerg,
Replace both the Aux shaft outboard bearing and shaft O-ring. The Outboard bearing includes a proprietary seal assembly which is not available separately.

Hope this helps.
Sincerely,
Dale

Hi guys,

New to this forum after searching t’internet for Husaberg sites.

I have an ‘04 FE550e that has developed at weep (coolant) from this hole last weekend.

Question is, can both seals be changed just by dropping the coolant and removing the small water pump cover or will the engine side casing need to be removed to get at them?

Planning to have a look this weekend and forewarned is forearmed as they say. I’m new to this mechanic lark, but willing to learn.


Thanks,
Marv.

the sidecover contains the ball race bearing and that sits over the 'O' ring that dale describes. so you'll need to take the sidecover off for this one. i suggest a new sidecover gasket or two should dangle from the wall of your workshop (ok tiny shed!) because when it's all new, you'll have to fight to get things to move!

the oil seal can be done with just the waterpump cover off.

quite right. strike that last sentance from my evidence your 'onour!

i always think of it as an oil seal keeping oil in and water out but you're right-it keeps the water in!

Fellow Husaberg owners,
I have a (pain in the but) oil leak coming from a weep hole.

First of all I had the same problem as you.. but let me remind you that what you see coming out of the weep hole is %90 radiator liquid that looks like oil after evaporation of the water and the glycol is left behind.

So just replacing the water pump seal is enough.. but that seal is really tight. You'll need sort of special tool to take it out and fit the new seal in order not to ruin both the seal and the socket in the side cover like I did
