Torque wrench

Do you use one? What type and size? I been reading you should use one rebuilding engines?

Re: Torque wrench

Yes . Use one . Specially for the critical torques like the cylinder head .

I have and use a beam type torque wrench . The same one I've had for years .

A beam type has to be 'calibrated' or re-set , occasionally . That's a small price to pay for knowing exactly what you're working with .

Click type wrenches can be 'off ' and the user not realize . Obviously , more so in the lesser quality wrenches .

Re: Torque wrench

Ideally you want to be using a TW somewhere close to the middle of its range.

Don't buy Harbor Freight's Pittsburgh. It's a POS right out of the box. I can't afford Snap On so still looking for a decent mid-price one. I'd really like one though.

Re: Torque wrench

i have a 300 + dollar snap on torque-o-meter

a buddy of mine and i were drunk one night and got into a pissing match about torque wrenches, he challenged me to a torque off

we hooked the 1/4 drive click type HF $8 torque wrench to my 300$ snap on and they were damn near dead on.

of course, qc on all that stuf is terrible so you could definitely get a lemon, but i was convinced. I still like my snap-on because it has a nice big dial gauge but the HF clicker was pretty impressive.

Craftsman are decent tools.

I still use my fathers old click type, it must be forty years old.

Old tools are the best. Craftsman is Chinese shit now. I had a socket split open on me. Couldn't believe it.

I keep looking at garage sales hoping to find one.

Re: Torque wrench

I have a click, beam and dial torque wrench from SnapOn brand and some Jing-Jang-Jong something-Ting-Wing-whatever brand. All are equally accurate in the range I use them in for mopeds and motorbikes, checked with a breaker bar and a 20 pounds weight hanging on it.

At least more accurate than people who claim they can tell the torque by feel.

(okay time for you torque-by-feel folks to start posting)

Re: Torque wrench

Should I have gotten a 1/4 " drive?

Re: Torque wrench

More useful range if you are just into mopeds and pedal bikes.

Yeah this is the one we tested against my '0-12 ft lb' snap on torq-o-meter dial gauge torque wrench. Definitely +/- .5 ft lbs maybe better but it was hard to tell with a click torque wrench

Re: Torque wrench

Probably Fred /

The Harbor freight one are OK but you have to test it against a known good brand one to see if it’s off or not! I myself got old craftsman ones

Re: Torque wrench

That looks exactly like the 3/8 " model from Duralast! Exactly! On company makes all!?

Mine must have been a lemon. Couldn't even get it to adjust. The postage going back was almost as much as the wrench. Maybe I'll risk it again.

Re: Torque wrench

Short answer is you really need more than one. The one used for cylinder head nuts is not gonna be one I'd use to torque the drive sprocket or a flywheel with.

Re: Torque wrench

bought myself a digital snap-on unit for £400+ 3/8 lights up when youre getting close and buzzes when to stop. really great tool/toy if youre thinking of going big :D

Re: Torque wrench

Well, I really read and learned a lot today!

Re: Torque wrench

he challenged me to a torque off

HELL YEAH

Now I want to have a torque off.

I don't know if I can juice anyone into a contest though. I'm about the most un intimidating person.

Perhaps if I make a holster and come on the set with the wrench slung low.

I Can't say i can guess torque by feel, but i'm damn shure i know when something is torqued enough. I don't think i ever saw a torque wrench in my life, just don't act like king kong when torqueing? Things and everythings fine.

The initial accuracy is there. What'll be interesting to see is the test of time.

Snap-On is nice but I'd never pay full price for one. Once I got my tool account paid for I turned to ebay and built up a collection of 5 nice used ones for just under half what the truck price was. The biggest iirc is 200 ft.lb.

Still use an old craftsman beam and two old snap-on clickers too. (edited)

Torque wrench is important as you don't want to strip threads, or lose parts as you ride.

1/4 and 3/8 torque wrenches are the most common ones when working on moped, click type wrenches can also be calibrated (they sell digital torque adapter) so you can use it to calibrate your wrench, or you can watch youtube video on how to calibrate torque wrench using rope & water container. I used to have "Pittsburgh" brand 3/8 wrench, it worked fine until it fell from 7ft heigh, then it stopped working. Purchased EPAuto brand 1/4 and 3/8 wrenches, been using them for years, they were also calibrated correctly out of the box, if your in the market for buying one, make sure to read reviews and be careful not to drop it.

Re: Torque wrench

Thanks Simon I'll note these for when I wrench on my Bullet! Got any idea where I could find torque specs for Vespa Bravo?

Re: Torque wrench

Chöschi21 C.K. /

Yea, i use a Tohnichi Dial Torque Wrench, 3/8" Connection, doesn't klick, just shows were you are at.

I don't use it for Heads and stuff easy to do with a normal Wrench, but for the Flywheel, Clutch and things like that it's sometimes quite useful, specially on Sachs 505/504/535 and 508 Clutches.

I need todo this for my Puch! Having to google/wiki with dirty oil moped mechanic fingers every time you need to know a torque setting isn’t easy!

Interesting

Re: Torque wrench

Is a Davey Jones wrench any better than a Peter Tork wrench?
