Intermediate housing / Mid shaft leaking *Pictures*

[oldphones]

Hi guys
Whats your experience with this problem? Is this mid shaft hard to get sealed?

I just put my ski together and i found out that the intermediate shaft is leaking while running the ski. Its leaking between the housing and the mid wall.
My ski dident have the shims that you see in the manual but its still aligned with the axel and that shouldent effect the sealing.

The service manual dident give much help on installation but i put the grease inside just as it says.

As you can see in the picture the grease i put in went out with the water.

The rubber seal on the back of the housing dosent look damaged.

Are you suppose to use any sealant on this?



/Thanks

no sealant , but no grease either , that's probably why it's leaking , i needs to be clean and dry , i will suspect the grease help the rubber lip slide out the way under pressure to let water go by .

I think it should be. Thats what the manual says and according to this thread there should be grease: http://www.greenhulk.net/forums/showthread.php?t=94905

It was clean and dry when i fitted the housing on. Then i filled it with my grease pump as i understand is what you should do?

Thanks

the rubber seal is what needs to be dry , yes you put some grease on the fitting , but just some , not to the point that blow out .

Yes I put it through the grease nipple and then pumped around 30 grams. You think its possible to put to much grease?

From what i can see any excessive grease will go out through the axel channel. The grease needs to protect the housing from eroding?

don't use any more grease , just wipe everything clean brake clean the wall where the rubber seal seats and try again.

Make sure it's not leaking from the drive shaft hose. If the clamps are over tightened, it will break the material below it and water will push past it being it's no longer a good seal.

Yes it is possible to put in too much grease and blow out the seals. Not sure if that's what cause the failure, but I do half a pump of grease once every 30 hours with the engine running.

Hi guys. Thanks for the info!

I have now cleaned the wall with break clean and the housing with isoprop.


That gap is not suppose to be there. Even if the housing is sealed to the mid wall the water still find its way out through the grease channels since the housing rubber gasket is broken.

No wonder the water took all grease with it and splashed it all around the hull.

Turns out the rubber seal on the housing cant be replaced since its glued on there. You have to get a new housing and thats 200 bucks.

I have put some(a lot of) liquid gasket on to seal it up but i dont know if it will work cuse its a lot of pressure here when you run the ski at full throttle.

Its worth a try.


In the future i will recommend to add grease slowly and careful. And always have the engine running so the grease gets equally spread in the bearing.

keep fingers crossed.
