Mystery Oil on Clutch Side?

[RobWCanada]

Hey all,

Anyone have any ideas what this could be? I just took the bike out of storage and noticed this today after a good 200km ride. It’s not anything crazy, but there’s clearly a thin film of oil there. I use DuPont chain lube so I doubt it’s coming off the chain.

With I can’t see anything coming from anywhere, but will take off the chain guard to get a better look behind there.

Just wondering if anyone has any ideas what this could be.

Note that the oil was overfilled slightly in the fall, so I’m wondering if that has something to do with it.

If it were my bike, I would take the plastic sprocket cover off to clean the oil.

While it was off, would take a better look as to where its coming from.

Maybe the case cover screws need to be check for proper torque...

Maybe the seal on the output shaft is blown...

1st step, get a better look

Yup, totally. Planning to take the sprocket cover off today. But still quite cold up here in Canada. I was riding yesterday and it started to snow!! Totally wasn't dressed for it either.

Ok, well, still damn cold up here. 0°C today with 20 km wind. I don’t have my bike in a garage either, but it’s covered.

Anyway, I haven’t “fixed” it yet but I’d say this bolt is the culprit. NONE of these bolts were tight. I could have unscrewed them with my hand. I suppose they were not torqued down properly. I’ll look in the service manual for the torque value. I took the bike in for service in the fall, maybe the guy didn’t torque them properly. But I dunno if they even took that sprocket guard off. So who knows.

I’d like to put Loctite 243 on there. Oil proof (vs 242). Anyone do that?

The bolt circled had oil all over it and the hole in the sprocket cover was coated in oil as well. I don’t see oil coming from anywhere else. But all three of those 8mm bolts were loose. I’m 99% sure this is the issue.

Dont Loctite it.

Normally sprocket guard doesnt need to come off at the first service... (on my 401 many of the screws needed re-torque'ing so...)

Torque spec is in the manual... there are two tables with torques, the generator cover is in the motor part.

Should also be listed in the service manual for changing the chain / sprockets

I have a snowmobile and Loctite EVERYTHING. Lol

Why do you say not to? This is precisely why I asked…because I’m not sure to working on bikes and tend to follow the manual (which doesn’t mention Loctite, 243 is blue)

I also noticed last night that the torque is in three different places in the manual and has three different torque values.

Wheels, pg 122, 11 nm, 8.1 lbf ft, 97 in lbs
Engine, pg 173, 10 nm, 7.4 lbf ft, 89 in lbs
Alternator cover, pg 232, 12 nm, 8.9 lbf ft, 107 in lbs

Just thought it was peculiar… I’m gonna do the 12 nm, like you’ve pointed out. Gonna clean up the chain lube that’s in behind the sprocket cover first. Hopefully it gets warmer soon. It was snowing today lol!!!

Do you have a repair manual? I ordered mine from Husqvarna on dvd for like 10 bucks.

Yup, I have it in pdf, that's where I got all the page numbers from.

What about the Loctite? Is there a reason why you don't put it on? ...like I said, the manual agrees with you, no mention of Loctite. My first thought when seeing loose bolts is to put Loctite on and torque to specs. I know that a bolt tightened to correct spec shouldn't technically loosen off but with extra vibes who knows...

I personally am not in a position to "correctly" answer the why part... I just wouldnt do it.

Maybe so you can periodically check for "snugness"?

I know I go through my bike and check the important stuff, without loctite, for "snugness" regularly.

I bet a engineer or specialist could answer the why or why not loctite question though...
