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.

regards

Taffy, I don't believe you said " the oil seal can be done with just the waterpump cover off." You know that's not true!! It's the water seal that can be changed that way.

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!

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

Re: Weep hole leaking oil

Mdogruc.
Sorry pal but you missed the boat on this one. My weep hole leak was pure petrolium. I replaced both seals anyway, side cover gasket, shaft o-ring, water pump impeller, impeller snap ring and water pump gasket, then added new oil.
Started bike up and warmed it up. Took it for a nice ride to get it to operating temp. Everything wes fine. Then I took it to about 75% throttle and when I pulled in my drive way oil and water were leaking profusely out the wheep hole and oil streaming out the side cover at the 3 o'clock position. Shut down the engine and all the leaks stopped.
Now wouldn't that just make your day?
