MG TD TF 1500 - in/lb torque wrench

Where in the world do you get an in/lb torque wrench that reads as low as 6in/lb? The lowest I can find is 20 in/lb. I am trying to finish my rear end conversion.

Just a suggestion - you could use an ordinary spanner together with a spring balance, just hook the spring balance on 6in from the nut a apply a 1lb force! Matt

Rob, I got mine by doing an online search. I would tell you the model and make but Alex Waugh has it right now. One thing I would strongly recommend is that you purchase a dial reading in/lb torque. Alex and I found that it made checking the measurements, as you turn the handle around, very easy to read.

If you go to my web-site, mgtf54.blogspot.com, then click on the 2010 "arrow", then click on the October "arrow", and then click on "Part 2 - The Installation of the 4.3 Differential" , you will find a couple of photos with the in/lb torque in use. If you click the photos to enlarge, you may be able to see the brand as well. It was one of the best tool investments I have made.

Rob, Just curious...it's been several years since I did my rear conversion. Where is such a low torque setting called for? Is it for pinion bearing preload? If so, I used the string and balance that Matt suggested.

Rob, Now I see it...it's all coming back to me (slowly)! I looked at John's blog and he notes that Carl Cederstrand actually recommends 11-13 in/lbs. for the preload. That is why it didn't ring a bell at first. Since I used Carl's manual for my work, I used tha string and spring balance for the higher value and it worked out very well. I have no reason to believe that purchasing an expensive torque wrench would have worked any better!

A torque wrench with a range of 0-60 is never going to be accurate at either end. To get an accurate 6 in/lbs you ought to have one with a much smaller range, like 0-20.

Rob,
We were scratching our heads too, when we did this. We came up with a different solution than using a wrench. You can see a picture of it on Bud Krueger's site at http://www.ttalk.info/Ashworth.htm. I believe it is picture #33 and there is some further explanation in text above. We put a beam across the flange and positioned a one pound weight on it. When it got to 6" away from center and the beam started to move, we had achieved the right torque.
Good luck with the project.
Safety? Fast?

I got mine at Harbor Freight a few years back, dont know if they still carry them in inch lbs.

I think 11-13 "/# is with seal installed.

Thank you everyone. I used the beam and weight method scott used and had no problem. Sorry for the late reply.

Just for informational purposes, a inch pound dial torque wrench is not something the average part time mechanic wants to buy, unless of course he has a pocket full of jingles burning a hole in his pocket. A cheap one will cost over $100.00, a decent one will cost around $250.00 and they continue on from there. And, then there's the digital $$$! PJ
