Destroyed my Swingarm, take my advice.

The moderators here are a joke. They don't do anything nor do they ever respond to any emails. Without good moderators this forum is going down the tubes. Keep reading and you will see the evidence.

 

Geeeeeeez! Lucky nothing catastrophic happened to cause a wreck.

 

:hss: you are a lucky man. The man above is watching over you.......
Go buy loto if I were you.........Wow that is in sane :crazy:

 

A guess would be you actually over-torqued the studs. Possibly damaging the threads on the hardware or the hub. Allowing the studs to "walk out" over time.

Definitely replace all the hardware. Take a good look at the sprocket & hub for damage. If there are deep impressions on the sprocket from the nuts consider replacing that as well.

You are very lucky.

 

Wow! That is some Awesome carnage right there.

Having said that I'm super sorry about the damage to your bike and am very glad you are ok.

Quite unbelieveable.

buy a torque wrench !!!

So you can properly torque bolts/nuts then properly retorque them every so often - a 3lb sledgy is a stud fucker, NOT a torque adjuster...

You are the one who stated you used a 3lb sledgy, don't insult me by stating how insulted you are are when you clearly have no fucking idea how to torque a bolt - "I tightened the sprocket bolts with a 19mm wrench and whacked the end a few times with my 3lb sledge to get them nice and tight (approximetly the same force required to loosen them). " Anyone with an ounce of mechanical aptitude knows the force required to undo a bolt is NOT necessarily the torque required to do them up...

And yes, I think you over torqued them, the same issues are common place and well documented on car/truck wheel studs which are over torqued...

 

"I did an inspection on the one stud that came out the most and did the damage. The threads in the hub are in perfect shape. I even cleaned the aluminum out of the threads on the stud. All fine now."

hint #2...cleaned the aluminum out of the threads !!!!!! ---- 3 lb sledge

 

That tells the whole story of what you did and the type of mechanic you are. A 3lb sledge as a torque wrench for tightening studs in ALUMINUM.!? Yep close enough. The only question remains "for who"? Sorry but with what happened I can't believe it couldn't be felt or heard. Your lucky, real lucky..................

 

Shit Jason...chill.....if ya dont want GOOD AND THE RIGHT advice dont fucking ask

 

How bout using a 2lb torque wrench or two 1lb torque wrenches or a framing hammer?

When a dude states he can apply a recommended 70-80 foot pounds of torque with a sledge hammer and then suddenly becomes a master mechanic, the BS meters peg out..

 

There's a lesson here: hitting a wrench with a sledge is not how you should tighten anything on a vehicle.

 

yeah I am very experienced mechanic but I don't have a freakin torque wrench but I got a sledgehammer... that will do... really dude

 

I think you answered your own question and I'm with Duccmann, you have to expect advise or remarks that you may or may not agree with.

As far as working on stuff myself, if the bolt or nut is for something trivial, I'll use my experience and tighten to what feels right, but if it's something like a brake caliper, axle nut, or other important fastener, I grab the torque wrench. Yes, it may be a $50 part, but it could have been your life or someone else's if this were to have gone to a more catastrophic level. I will say that I have not seen any FSM tell me to take a 3lb. sledge and give it a "close enough" whack!

 

I like using an Eastwing framing hammer for torques above 80 foot pounds. What about Newton-meters, does that mean you eat a few fig-newtons then get a BMFH and beat you shite to death? Was trying to quote BB but couldnt, gawd for-give meeEEE ope2:

I trust my feel with a t-handle and use electric impact shit to tighten/take off smaller stuff. I also trust my air-impact stuff with the appropriate square (3/8 - 1/2. sorry no 3/4 stuff cause I dont work on trains.) :lol:
