• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Loose engine mounting bolts !!!

I had the tank off my '09 TE610 for the first time today to do the PU Lamdarectomy. The first thing that struck me was what terrible fuel disconnects ... I cannot call them QD's as nothing quick about them and such potentially brittle plastic. Despite careful attention still did not get the cross-over clicked in fully and had a boot full of gas on first ride! Anyone replaced them with the ones with the metal press releases like on BMW etc?

The second and more alarming discovery was that the two engine top mounting bolts to the frame were properly loose - I mean rattle loose!! There was even black metal oxide deposit from their continual vibration. Why no locktite or Nylock nuts on these bikes? There were not even the signature brass washers :confused: If your scoot has a strange rattle go check... in fact check anyway (can probably get your hand up there).

I am just rebuilding my sm610 08 i noticed what you are pointing to...almost every bolt is loose. It is enough that one bacames loose, stronger vibrations take care for others to came of. Those engine plates are made from aluminium. I sugest that you take it down and check it, if it is damaged. In my case it was rubbing so long (ex owner) that alu plate bacame thin and it broke. There is one plate on the top and two in the front of the engine. Check them all! Ill post pics tomorow!
 
Yeah checked the others after this as a matter of course ... and a number of others for good measure. I know thumpers like loostening up things but this is just poor spec and assembly ... Giovanni was off on early lunch :o
 
good observation,sometimes the lower front ones have come loose and we have seen a few engine mount bolts come loose on 630s as well.dan
 
All of those bolts on mine came loose. Loctite and torqued down and haven't had any problems since.

Double check your fuel connections when you put them back. Mine came loose (had aready rode about a 100 miles on it since taking the tank off) at the carb connection and dumped 3 gals of gas out riding down the road at 60mph. Couldn't figure out why the guy behind me had backed off so far till I ran out of gas. Surprised I didn't wind up being a human torch.
 
great shout fella. my nuts had completely shaken free of the bolts on my '08 610! :eek: have now replaced with nylon threaded!
 
These threads make me laugh a little. I've never seen a bike that needed so much locktite and nylock nuts.. Tonight I will check the engine mount bolts. What next???? ha ha
 
Interesting, because sm610 has no vibrations if i compare it to smc625. As i mentioned, ex-owner diden´t notice anithing (because it was hard to look under the bike)...first pic is a top plate. One bolt was already missing, other one was just on the end. Result is damaged alu plate. I have new one.

On the second pic, there are front-end engine plates. I assume that top plate made it posibile...much stronger vibrations wore delivered to front plates. One of them even broke on both ends. Another plate is damaged as well.

I will mount new plates as soon as i am finished with engine, glue them with Loctite. They wont move for a milimeter in future ;)

Check yours as well!

Click to expand...

These threads make me laugh because people will actually ride something without goin through it themselves and nut n bolting, and loctiting everything that should be.. loose bolts on an unmaintained thumper???.. no??!!? Lol...
 
Hilarious indeed. So many people laughing about this thread - really makes me happy especially this time of the year! :D

I think most of us know that thumpers are renowned for loostening nuts and bolts (and KLR's are probably the worst in my experience but maybe I have dicovered another contender) and YES I discovered these loose bolts by the very fact that while I had the tank off I was checking through (read: maintaining)things and discovered them. The electrical loom that I was adding a few extra cable ties to actually makes it hard to see the top bolts. So basically I was giving a thumbs up to check them because most owners doing their "nut n bolting" will not be removing their tank as part of this recreational activity. :thinking:

What makes me laugh (or rather NOT) is that a sophisticated bike like this can be assembled on a modern European assembly line with such disregard for basic engineering! One somehow expects to have to do the afore mentioned "nut n bolting n locktiting" on a Jap thumper but on a Husky?! Go figure.

Yeah.. well maybe it's just me.. But I'm not even getting on anything, ESPECIALLY with only 2 wheels that I haven't nut and bolted previously.. Unless it's a friend's that I KNOW also do the same.. And if you're only nut and bolting what you see without removing panels, tank, etc.. Why bother... Sounds like the first time you had the tank off.. And you rode it previously?? How long were they loose??? From the dealer?? From the factory?? Who knows I guess....A GOOD dealer will go over the WHOLE bike, not just the pieces he assembles... But yes. reminding people to check EVERY bolt on WHATEVER bike they ride is always a nice idea.. :cheers:
 
Yes I think it is just you ;).
Do you first go through an entire bike (or car, truck!?) before you take it for a test drive from the dealer? Or maybe you trust your "GOOD" dealer has done it...or rather his fresh appy back in the workshop with a hangover? Anyway my life can accomodate a little calculated risk under the banner of 'adventure' and yes I must confess that I have ridden countless bikes over 45 years without any anal pre-ride boltin 'n nuttin routine. But then that is "just me" and different strokes for different folks I guess.

And yes this is the first time I have had the tank off the bike - only had it a few weeks. When I first got it I did a good once over inspection and checked and tightened everything obvious and visible (this included taking off side covers etc). Bike had been dealer serviced and pretty low mileage. Have concentrated initially on getting to know the creature by riding it and now have been stripping it more to get to know the 'build' ... and this is where I have been somewhat surprised. I rest my case.
 
What brought me to Cafe Husky in the first place was that I found here a fair assessment of the (then) new 630 and a place where criticism as well as favourable comments were posted without fear of personal attack or derision. A motorbike is NOT an object that should have to be stripped and inspected before daily use. Even if a rider does not do his own maintenance, most owners will have it done by a maintenance facility. I am personally grateful for this thread and I inspected my bike to ascertain whether it had the same problem. Please do not start denigrating other people and treating them as if it were their fault when they discovered shoddy workmanship.
 
Daily..?? Who said daily?? How bout ONCE before you put your life on the line and get on those two wheels?? Not "attacking" or "denigrating" anybody.. I said also too maybe it was a good idea to remind people. Maybe its a lil more common sense to me, being taught to me BEFORE I even got on a bike at 5yo..Personally, I dont care who the other person is, or how "upscale" the manufacturer is thought to be, if it fails, on two wheels it can EASILY be deadly, so I personally wil not get on anything unless I have been through it or I know that the owner of what I'm gettin on operates the same and takes life and limb just as seriously.. How can anybody even mutter "shoddy workmanship" when they hadn't taken a proper look in WEEKS or EVER?? Maybe it was the way it was supposed to be when it left the factory and/or dealer....He said it was serviced by a dealer I guess.. What kind of service if they didn't even take the tank off?? certainly not a predelivery inspection.. If so, I'd have a talk with them and/or probally wouldn't trust them very much..Who knows IF it wasn't looked at for WEEKS..?? Thats about as irresponsible as not being sure what your riding... Your crash CAN hurt others...
Newsflash.. Thumpers vibrate...Some more than others, some less... Vibration loosen things, and loctite helps with that as well.. Also.. you should tie your shoes before walking in them..
Blaming poor "Giovanni" who assembled the machine weeks, months, year/s, MILES earlier and saying "shoddy workmanship" is so much easier (especially since he's not here in front of us or in the conversation) than taking some responsibility for what you ride I guess...Sorry if I hurt your feelings for saying so.
 
The 630's have the dohc top end so no upper mounts. Same bottom end as the 610 though. Anyway, we have to keep all the mounts secured with loctite.
 
i checked all main bolts and casing bolts after 300 miles.. will do so again at 3k.. im sure they will come loose.. however i think manufacture should at least use nylon threaded bolts as a precaution.. id be pissed if my sprocket fell out like the other guy on this thread.. yes my jap bikes that dont vibrate nearly as much has nylon threaded bolts on the rear sprocket..

be warned and check bolts guys.. it sucks but it is what it is..
 
Boils down to basic preventitive maintainance --check mine at every service as i have found the bottom ones come slightly loose. Even found the one on the swing arm on a 610 come slightly loose --
