Oil leak from the left side cover (2007 FS550e)

OldMan · Jul 6, 2014

Hi guys!

I went to my garage to test a few graphics I'm doing for my Berg and as soon as I got there, I immediately changed plans. This is what I saw:

Tried to follow it's path in reverse so I could find out where it came from and got more droplets of oil allover:

On the frame

Under the engine

From the case to the frame

This is the view from the left side

The oil cap was no dirtier than usual

This is definitely dirtier than usual!

Moving up, there's oil even on the cylinder head...

Then I cleaned as much as I could, started the engine and left it idling for a few minutes looking for leaks. Not a single droplet. It was already hot enough around the engine so I turned it off and let it cool down, while still looking for leaks. And this is what I found:

(Notice the bubbling?)

Took a closer picture:

I guess we are looking at the closing cover (80036010050) completely out it's place. Let me just remind you I'm a complete noob in mechanics but this still looks weird to me.

Closing cover - #10

What in the world has happened here, and how am I supposed to solve this?

Thanks!

I went back there, now that it's completely cold.

The cover was a bit stuck, but I was able to push it inside. But as soon as I let go the cover comes back out as if it had some sort of a spring.

I guess I was really lucky not to get hit by that cover followed by a jet of hot oil on my leg...

Now, for the experts (*cof* Taffy *cof*) what is that cover for? It looks like someone decided to open a window on a wall and then covered it with some cardboard.

That plug (#10 in the picture) covers the end of the cam shaft and on your engine it's mounted backwards!
If you take off the head/valve cover you can see that there is a groove in the hole where the plug goes. The lip on the plug should be mounted in that so that it doesn't come loose. My advice is, buy some new o-rings (#11 in the pic), flip the plug so the lip goes in the groove and mount everything back with some liquid gasket and then your good to go.

You are 100% sure about it? I think that there is some space left to allow the oil to get to the other side of the bearing.
As far as I remember mine cap is mounted exactly the same way (using new orings) as on posted picture and it doesn't leak at all

Looking at the manual, I wouldn't say it's mounted backwards either...

ghost is right, trust him

toivias · Jul 6, 2014

You are right guys. My bad.

OldMan · Jul 7, 2014

@toivias, where is that pic from? Share a link please?

It is a printscreen from workshop manual for 2004 husaberg 650.

Thanks! Just got it here if anyone is wondering (page 56): http://husaberg.org/attachments/ser...berg-workshop-manual-husaberg_2005_repair.pdf

All sorted and everybody happy? Good! :hathat7:
As a bonus the plug looks a lot better the right way around.

Thanks for the help edelweiss! :thumbright:

toivias was also right. it was a fight to persuade the old man.

I personally think that someone who installs the plug this way should reconsider if he is the right man in the right place, if it was a mechanic. and as the bike owner I would be very nervous about what else can be screwed inside the engine. I have an iscription on my plug. it says that the previous owner is a ****. it is very decorative according to my opinion

I was saying exactly the same on the other day to a friend. If he managed to screw it up on this cover, I can only imagine how bad the rest of the engine might be as he was the one to change piston/cylinder/bearings...

need help guys

Today I was practicing some wheelies and found some oil on left engine cover...
Cam plug is mounted properly.
I have checked also this http://husaberg.org/mechanical/6514-should-i-weld-weep-hole.html and it looks fine.

Any ideas where should i look for leaks?

bushmechanic · Jul 26, 2014

try this one

google "water pump seal" kit

"orangeberg seal kit " + weephole site:husaberg.org

Bush as always right

Water pump gear/fan circlip and neddlerol. are completle gone... they for sure were there before this happened. How far cold they go with water - any ideas where should I look for them?

EDIT:
how bad does it look? Do I need new shaft?

bushmechanic · Jul 28, 2014

that shaft looks OK, just make it smooth with some #400 paper

use a magnet to find as many metal parts as you can, (its a ball bearing not needles) many oil quick oil changes will also help.

I am not sure if You understood me - bearing is fine.
The problem is that needle (56) and circlip (54) went with water somewhere into crankcases...
I will try to get them by magnet but I am afraid I will have to separate the cases anyway to find them.

bushmechanic · Jul 28, 2014

ah I see

i have used a really big neodiumum magnet moved around on the outside of the cases to find bits of gears stuck inside

so the parts are in the cooling system .. water passages around the liner ?

edelweiss · Jul 29, 2014

my guess: the circlip is in the zylinder sleeve area and the needle in the lower hose.
I think, the circlip must fell off first, the flow up was still present. after the wheel got loose and the needle fell off, the stream was not supported by the wheel anymore. thats why I think it couldnt go so far as the circlip did. I would drain the system by disconecting the lower hose at the water pump. to get the circlip from the zylinder sleeve area I would:
take the left cover down and blow water into the place where hot coolant leaves the head. if the circlip is there, it is impossible to get it out in the other direction, because the coolant passages (head entrance) are to small. if this does not help, try to flush the radiator, if still not there, think more and if there is no other idea, split cases. if the circlip broke into halves, it can be anywhere.
