Hi all. As you may recall I'm the guy who had a crack through in the bottom of my engine casing. That was this thread: http://www.cafehusky.com/threads/false-start-weird-clatter-noise-another-opinion-request.45337/ I just got the re-assembled engine back yesterday, so gonna start the re-install tonight. I did get the old case halves back and will post pics soon (sure enough a lot of internal cracks.) Now if you'll recall the mechanic felt confident that the small solid end piece of the right hand oil screen came off and did this damage. That appears to be the case- he sent me the old one back, along w/ the piece that flew through the bottom end. It's very tiny but, as we know, the tolerances in there are very tight and needless to say the forces are strong. Now me- back upon hearing this by phone from the mechanic and not recalling every detail of the screens construction- have had doubts. I've been searching and searching for a detailed pic of this screen. All the shop manual and parts fiche shows is a sketch which lacks any detail (in fact the sketch looks like there is no end piece to it.) So today I posted on The Garage (at ADVRider.com) to gain some pointers on engine re-install and, funny enough, LarryBoy over there posted a detailed pic of his '07 610 screen: http://www.advrider.com/forums/showthread.php?t=1034323 The scary thing is that his came apart also, but he caught it before it did any damage. Now I know, and believe, that many here have checked theirs and they're always clean and in good shape. Still, I'm posting this just to aid others as it appears that in rare cases these bad boys DO come apart, sometimes with catastrophic consequence (and to the tune of several thousand dollars, as I now know.) Again I'll post pics of my cases and screen soon- the least I can do after all the help you guys have been...can't thank you enough. I'm sure I'll be picking your brains again as I muddle through the re-assembly phase. Eric
Interesting. I think I've only had mine out once in 6K miles. Time for an oil and filter change and check it again.
Well put- I think it's just that, interesting, as I know that in what seems to be, oh, 95 plus percent of the cases a non-issue...something to not even give thought to. But, as with some other things, it seems that sometimes these simple things give way in a big way.
I have had the same filter come apart on my 06' SM610 !! I had to split my cases to inspect!! I found the metal bits but did not want to reassemble until I knew where it came from. It took me a while to figure out it was the oil screen end cap. Ordered a new one and could not find anything online regarding this issue so I thought it was a freaky isolated incident ! Apparently not!!
Talking about the two longer screws, the #4 we can't see in the picture, I can tell you that on the 610 the longer ones are these two: Probably, on the 630 this holds good. Anyway, when you don't know which are the longer screws among many ones, you can temporarily install them randomly without tightening them, just putting every of them in one of the holes. You should then be able to know the longer for the shorter ones, because, if a short one is in a hole designed for a long one, it will protrude less and vice versa.
At disassembly I use a piece of cardboard, sketch the perimeter of the part (like the clutch cover). I put a mark where all the screws go. then cut an X with a knife. A bolt comes off the bike then in the x of the cardboard. That way on reassemble I don't have to try and remember where it goes i just follow my picture. I like pictures!
Looks like I'll be giving Husky a call since my screen failed under warranty and Husky, cant remember the aholes name now eastern Husky rep, said it failed because the dealer didn't install it correctly. Looks like enough evidence of a faulty screen! I better check the screen on my other bike!
Where do you pull these out? where is it located? never cleaned these before Is this te operation? I have to remove both engine covers?
The filter in question is #1 in the drawings you posted. All you have to do is remove that side (the right side) engine/clutch cover. The left side filters are uncovered by simply removing that plate.
Yes- it's a "while you're changing oil" thing. The left side filters should be checked with every oil change. I forget the interval for the right side screen in question, but it's a pretty long interval and it's in the manual. That said, and based on what we're seeing, it's best (though inconvenient) to check it at every change. Also- keep in mind that when pulling that clutch cover there's a fair amount of oil that's gonna want to dump. When you drain the oil lean the bike as far as you can each way to get all you can, then lean it to the left (like on kickstand w/ no prop block) to minimize the mess.
When you re-install the right cover, remember to align the crankshaft with the oil pump shaft, or this could happen!
The crappy thing is, last time I wanted to do my oil change I tried to order the gasket and was told it wasn't available. I am the kind of guy that doesn't like to take things apart without the parts to put it back together. I have checked that screen twice and found it clean both times. Hopefully if I don't disturb it, it will be fine.
Thanks for sharing your pain findings Eric, its easy to ignore those sleepers when they're not obviously causing grief. Will do a proper oil change next time
Whats wrong with buying a roll of gasket paper and making your own? I can get about 6 water pump gaskets from £2 worth of paper. I put my right side casing back on with the original gasket because it was undamaged.
Worth following this fella's saga...I'm hoping it'll shed some light on what the core issue is here, as well as possible remedies so that we're not having to be paranoid about this issue. http://www.advrider.com/forums/showthread.php?t=507511&page=294
Good find. If I'm reading that thread correctly, with the drain bolt out, it is possible to insert back the screen filter too deeply so that when you you put the drain bolt back, you are crushing the end of the screen filter...
