Torque Screwdriver

[bash_brannigan]

I am in the process of rebuilding my first automatic transmission, and there are a couple of adjustments using a torque screwdriver (torque in the 10-30 in lbs range). AutoZone shows a torque screwdriver in their loan-a-tool program on the website, so I went to rent one and found that they are not known to anyone in the stores, and not shown on the in-store list, which is frustrating. I can't find anywhere locally to buy one - I have some time this weekend to finish up the rebuild so can't order online and get it in time. Also, at the risk of being thrown off the forum, I really don't want to buy an expensive tool for one-time use!

Anyone any thoughts how to improvise a torque screwdriver? I was thinking of some sort of t-handle and a luggage scale, but at 10 in lbs I am not sure I can get a scale accurate enough to work. Any thoughts or advice would be appreciated!

bit socket + in lb torque wrench?

Where do I find an in lb torque wrench that goes down to 10 in lb? Of the places I can find 1/4 drive torque wrenches, they start at 20 in lb, and I wouldn't trust it at the lowest value on the scale, even if that value wasn't twice the value I need to measure!

I have a little 1/4" drive torque wrench for that. what you want is a beam style, NOT a micrometer/click style.

they are out there...

You need to get a DIAL type in/lb torque wrench which starts at zero.

Ya know what bud, this took me all of 5.2 seconds to google.

Hopefully this solves your problem

Check a bike shop. A lot of carbon parts spec low torque ratings so guys don't internally damage the carbon part without realizing it.

That is the only one that i have seen to be worth it. .5 in lb increments 5-40 in lbs. Plus with that one you use bits so you can make it as long as you need to and can get various bit sets and lengths.

Apparently home depot has one as well but, whether it is worth it or not or if they even carry it at your nearby store....

Thanks. I did try Google before coming here. Google is what lead me to believe that AutoZone had torque screwdrivers in their tool rental program. I found out when I went to pick one up that they don't. What I am looking for is a way to get this done over the weekend, so unfortunately a link to a place in Colorado isn't going to help.

I can find many sources for torque screwdrivers, but none that are local, so I figured the combined wisdom on the board would come up with something.

What I think I will do is buy a fishing scale or similar, calibrate it using water and then hook it on the end of a wrench, adjustable wrench, or whatever I have that will work.

Thanks for the suggestions guys. Looks like I just have to hope that the method I have suggested will work - or back to Google on Monday!

Go to your local dealership for that make, find the transmission guy, offer him $20 to stop by your house on his way home with the tool he uses?

Well that certainly is interesting - a store not too far away shows 3 in stock, but I was in that Home Depot not an hour ago, and the tool guy assured me that they don't sell anything like this! If my hamfisted approach doesn't work I will drive over to see if they really have them.

Thanks for your help!

I'm sure you already know this, but if you go this route don't forget to multiply by the length of the moment arm.

An impact wrench?

Check with your local Firearms store. Many stock torque screwdrivers.

Also x2 of gunsmith tools. Wheeler has a decent clutch screwdriver that they sell in a kit with scope ring alignment rods and a lapping tool. I think the above torque wrench has been discontinued under the KD name and is now labeled Gear wrench, since Apex Tool Group is slowly ending KD.
