Torque wrench.. Left hand thread?

Hi fellas,

I'm attempting to put a 46mm nut back on the crank, because its a Left hand thread im afraid my (new) kincrome wrench i just got doesnt work for LH threads and that ive stuffed it trying to get it to click...

I got my dad who weighs 90KG or so to physically stand on the wrench to try and tighten to 130NM. So far, there is no more movement and it still isnt clicking.
Ive never tightened to this torque before, and the breaker bar i used to remove the nut had much more leverage.

Thanks for any advice.

Jake

Well, if the torque wrench is ~ .3m long, and your dad was standing on it, and it doesn't move anymore, you're done. Go ahead and continue on the rebuild, because I believe you've actually over torqued it. (or my math maybe way off, wouldn't be the first time )

Are you sure your toque wrench doesn't do LH threads? Put the torque wrench on a low value, put an old bolt in your vice, and try it out. Does it click or not?

+1 -- some wrenches have a little doo-hickey on the head that clicks, magically reversing the ratching action (and, therefore, the direction the torque will be read).

Left-handed torque wrenches are as hard to find as left-handed Crescent wrenches.

This is what I was thinking. Those LH box end wrenches too, damn.

This thread makes no sense.

130NM?


yea your most likely over torqued.
Someone smarter than me can do the conversions and math.

(Guzz, I see you've done the math, 0.3cm, oh my!!)

90KG that's like two stone?
what is length of torque wrench?


Beam type torque wrenches for LH work, for future referance.


It's going to be just fine.

Beam wrenches work both ways , Good clicker torque wrenchs work both ways , I know my Proto's do . but you better check it before you bet your motor on it . SEYA

Ok, I will admit something.

I was working on my car the other day and there was one bolt that required 130 nm torque. I think it was that much, can't remember, but I do remember that my torque wrench didn't go up to the required torque. Trying to get the nut off was a bitch though, took my longest breaker bar and I still cracked my socket.

So I just set the torque wrench to the highest it could go and went to town on it. I have to say that I couldn't physically get the damn wrench to click it was so high a torque and in a bit of an odd position.

So, I got out the jack out of the car, grabbed a chunk of 2x4 (to reach). Kept cranking up the jack, started to hear the 2x4 creak a bit, then the blissful sound of the "click" of the torque wrench. Backed off the jack and said "I'm done." and finished up the project. If that nut comes off, I'll be really surprised.

Well i just rang kinchrome and it doesnt do left hand thefts

most likely overtorqued a f**king crankshaft nut, the worst...

What problems would this cause on an LC8 engine?

does it press on or into a bearing, or seal?

change those!!!


The nut will be stout, I would just check for garfed-up threads and reuse.

Its for the timing pickup ring, it clamps against the washer & sprocket. Maybe the bearings weren't damaged then?

As long as everything felt smooth as you were torquing its probly fine , I tend to overtighten everything , I dont have things falling off my bikes . I also dont have jap bikes , I got tired of broken bolts and parts . SEYA

Do the math.

130 Nm is 130 N (13 kg) applied on a lever 1 meter long.

Or for you yanks, approx 29 lbs and 3.3 feet.

Not an awfull lot.

Paul.

When did you last see an torque wrench that was 3.3 feet long?!?!?! (outside big industrial assembly). Most are 1 to 1.5 feet long (12 - 18 inches, 30 - 46 cm) roughly.

So that 130 Nm is 96 lbs at 1 foot away on a lever.
