Dual 80 Destruction

Wow. Tried an impact or Breaker Bar?

 

[Buckgnarly]

Details.....
bolt/nut size?
ratchet drive size?
use of pipe/cheater?
Inquiring minds want to know......

 

[xwarp]

gotta give partial credit to the ratchet for the "snap" it must have made.

"snapped clear off!"

 

[chadster1]

Take it to your dealer and you will get another one. Next time, try either a non-flex head ratchet or a breaker bar.

Is that on the first gen Murano?
They love the control arms....
When I worked for Nissan we had ton of those...
I remember one the tech heating every bolt on the suspension they corrode easy.

You need a mini ductor so you can do.....

 

[snapmom]

Looking at where it broke, would a breaker bar busted too?

Maybe, maybe not. There is not as much leverage on the joint of a breaker bar compared to a ratchet. Usually, when a breaker bar fails, it is the square drive that snaps off.

That Chinese steel just doesn't hold up like the older USA made wrenches.

Even since Snappy when to China for the dual 80 production, the quality have taken a dive.

true, my snap on F832 which is marked USA in two places would have snapped the nissan in two

Is stirring the pot making your arms hurt?

If it doesn't, I'm sure all the trolling will!

Nothing like stirring the pot!

Well, if Snap-On would stamp USA on its ratchets, there'd be no pot to stir. I am a huge Snap-On fan, but won't buy any dual 80s as long as the USA stamp is missing.

...back to the thread!

I think I read somewhere where stamping letters into steel increased the strength by 48.2%. So if that ratchet was stamped with USA, it definitely would not of broken.

I also read where 76.2% of statistics quoted in internet forums were completly made up.

 

[BQuicksilver]

Doesn't SO rate these with some huge torque figure...like 800ft/lb?

If so, the "use a breaker bar" comments really shouldn't matter. I'd still use one, but with a rating like that SO is basicly calling it a breaker bar.

 

[Creditor]

Oh wait, I want to be the first to make this type of post in this thread.

My cousins girlfriends uncles babysitters mothers ex-husbands best friend knows someone who overheard a conversation in an airport between two guys who had a neighbor who knew that the ratchet guts were imported.

Probably the most valuable information missing from this thread is:


1. Drive size?
2. How much service has this ratchet seen?
3. What kind of service?

The op states "Nissan 1- snap on 0" Was this the first time he used it? Should he have used a bigger size? Was a flex necessary or would a standard head been a better choice? Regardless tools break and it's not always the tools fault, operator error comes into play most of the time and sometimes I expect it's just a casualty of getting the job done.

There you go injecting logic. Logic has no place in a thread like this.

Looks to me like you should have had the selector to "off" instead of on...maybe it wouldn't have broken.

That and a flex head ratchet shouldn't be used for a fastener that stubborn, regardless of the brand.

I'm sure that ratchet got wailed on WAAAY hard to break like that. A combination of heat, breaker bar/impact and penetrating fluid would have been the smart way to go.

But U-S-A = 3 letters and C-H-I-N-A is 5, so the China stamp would be 66.7% stronger than the USA stamped one!!

It's all there, clear as day, plain and simple!!

You have it kind of right....the only letters that add strength are "U" and "S"....the "A" actually takes away from the overall strength whether it be in "CHINA" or "USA". All other letters actually make the tool weaker, which leads to the next question, why use of "USA" as opposed to "US".......

Snap On found that only "US" made the ratchet indestructible, which led to an issue with Homeland Security. They were afraid terrorists would get a hold of a Dual 80 with "US" on it and would basically become invincible. So the gov and SO decided the "A" would add some weakness as well as security.

This is all according to what my brother's best friend's cousin's best man's sister overheard while being abducted by aliens in Roswell NM.

Yes!

 

[seth_man]

Ok well...

-3/8 Drive FHLF80
-No pipes, bars or other leverage devices were used
-socket was on a 19mm nut attached to a 21mm bolt being held by a gearwrench gearbox wrench
-Broke it with one hand
-Limited Access did not allow for use of a 1/2 drive
-the nut was red hot
-Ratchet is a little over a year old and has never really been used as a breaker bar.

i guess i would call it metal fatigue, ive had a few snap on impact sockets break in half lately so i dont know what the deal is, maybe their cutting some corners on quality???? on a side note, the handle broke but the head still worked perfectly, snap on guy came today but didnt have one on the truck so ill have to wait till next wednesday for a replacement.

Why do people heat the nuts up? Thermal expansion would make their grip tighter....

If you heat the nut until it is red do you have to wait until it cools enough to not be red when you touch a candle to the threads to draw the wax in?

 

[Pro-Painter]

I'm just impressed that the handle broke BEFORE the 80 teeth stripped. IMO, that says alot for the strength and design of the dual 80's.

All tools will fail at some point. It WILL happen. But in the case, SOLID hardened steel broke before the moving parts of a fine tooth ratchet did.

That alone speaks for it's self.

Opposed to what..heating the bolt up?

Please explain..would really like to hear the opinions on this one.

 

[amolaver]

heating them up to cherry (like the mini-inductor picture) makes them slightly plastic. whatever is holding them on - probably rust, not strain - burns off / breaks down / or has its bond otherwise weakened. additionally, if there is any thread locking compound it is broken down by heat.

in most cases, if you can heat them up to that cherry color, they'll come apart pretty easily. just don't try to pick up the parts when they hit the ground. DAMHIK.

it should also be noted that any heat treatment is essentially ruined if you heat something like that. ie those nuts/bolts need to be thrown away and replaced with new.

ahm

 

[GoBlue]

Hmm...seems Snappys far east quality controll is slipping!

 

[ibedayank]

if you HEAT the nut it exspands not get tighter/smaller


care to explain your point of view?

 

[ibedayank]

I have never come across a tierod/balljoint that i could not get 1/2 drive or even a 3/4 drive on by either turning the wheels or putting it higher on lift/jackstands

 

[G1GRANDEUR]

Used wrong tool for the job. That's why they make 1/2 drive.

You fail to read my son

Ok well...


-Limited Access did not allow for use of a 1/2 drive

 

[wheats71]

i have broken 3 snap on flex head 3/8 ratchets at the same spot
2 of them were dual 80 one 36 tooth
im sure the reason for for the breakage of all of them was the pivot
bolt came loose without me noticing it
red threadlocker is now used

 

[oldtools]

Diehard SO fan refuse to believe that dual 80 is made in China. But when it break, those same individual quickly change their mind.

If that puny joint is rated for more than a couple hundred foot pounds i'm a dancing teddy bear.

This is just one of the many reasons i dont use a flex head [regardless of brand].

where can i obtain a mini ductor?
