Loose bolts, again and again???

1198 Views 12 Replies 6 Participants Last post by  BelaySlave
I seem to have an issue on my new 575. I found most of the key screws/bolts came loose after a few rides on the new bike. I expected that and was checking for it after each ride. I used a medium thread locker on the brake calipers, rear der., pivot bolts, crank bolt, etc, etc.

The problem I am having is that the bolt at the bottom of the shock, where the rear end, shock and dogbone combine keeps comming loose after hard rides. When I first found it loose I removed it and it had loctite on it. I cleaned it up some and applied more loctite. However it has come loose two more times.

Any suggestions?

Thanks-

Are you using a torque wrench?

If so, torque value should be 125-150 inch pounds...
Yep, torque wrench and blue loctite

I use the two religiously and haven't had a bolt issue in the year I've owned the 575.
I haven't reapplied loctite and I just torqued to feel. I've only had them come loose the first time and thats it. Maybe try red loctite? Although you shouldn't need more than blue for as low torque spec as those bolts are. If it keeps happening maybe try contacting yeti?
This goes to show how clueless I am when it comes to simply maintaining a FS bike....

I had brought in my 575 to the local Yeti dealer and one of the mechanics (who is also a member of MTBR) was easily able to jiggle my rear suspension by grabbing the rear wheel and moving it back and forth. He told me that I should always check this on a regular basis.

Maybe I should tell Santa I want a torque wrench? Any good recommendations from Sears?
You need 2 torque wrenches

One wrench that measures in inch pounds and another in foot pounds. I got mine from Valley Tools in Boise. They are not cheap but they pay for itself in the reduced number of stripped bolts you have to tap out or the number of times you have to take it to the shop...
Alternatively-you can always swing by and use my wrenches (I'll only charge you 1 beer per use...hehe)...
I read in a magazine that the beam style torque wrenches are better for bike applications. So, I went with that style. Well, I also didn't want to spend an arm and a leg for a high end one either. Sears torque wrenches, from what i've been hearing, are probably the one tool that isn't warrantied. I purchased my Park torque wrench from REI.com for 40 bucks.
I must admit I torque by feel. Has never been an issue for me. Maybe it is now.

FlipinIdaho, I assume you live in Idaho, am I wrong? Anyhow fyi, multiply by 12 to convert from foot lbs to inch lbs and divide by 12 to go the other way. It is important however to use a wrench that fits your needs. I.E. don't use a 200ft lb capacity wrench to try and accurately torque something to 2ft lbs (24 inch lbs). It won't be accurate like one that measures from 5inch lbs to say 100 inch lbs.

Thks for the advice, maybe a decent but inexpensive wrench is in order.
Yep-I'm an Idaho boy

I work on a lot of bikes and if you're going to be putting bottom brackets and cranks on bikes, you'll want a ft-lbs wrench... The problem I typically have is finding all the appropriate adapters for all the bb cups out there... Here is the workbench...

The rest of the room...

this is most, but not all my bikes... so many toys-so little time... The poor 575 (on the right) should get her Pushed fork back tomorrow...

Wow, looks like a bike store.

Didn't mean to talk down to you about the wrench conversion thing, was just trying to be helpful. I can see you don't need any help from me, haha :D

Thanks for the offer of the use of you torque wrenches. Its quite a ride from Az to Idaho so I'll call before I make my way out, Lol.

How do you decide what to ride?
Absolutely no worries

I didn't think you were talking down about the TW's... I just didn't want anyone to use a in-lb torque wrench for installing a BB since the in-lb TW's typically have a shorter handle and less leverage and you'll destroy the spring if you overtorque.

I should've quoted Belayslave. He's the Idaho dude I was offering the use of my TW's too, although you are more than welcome to them as well. I think this is why my little wrenching cottage side biz does NOT make any money. I work for beer too much! hehe.. On a serious note, I specialize in SS conversions for people so the use of TW's (and business insurance) is critical in this litigious culture we live in. Heck, I make sure that the chainring bolts are torqued to spec when I'm working on customer's bikes.

That's funny... Mostly I decide based on what trail I'm going on but also what mood I'm in... it's good to have choices..

He did this conversion for me recently....



...and it's all I've been riding last month!!! My poor Yeti is just sitting in my equipment room feeling like the neglected wife of an airline pilot! I started SS'ing earlier this year, but this one that flip did is alot more XC friendly than my other bike that in comparison was a pig to ride.
