Vintage Torque Tool

[GT1929]

How to use vintage apco mossberg dial seems to go 24 inch lbs. If torquing head to 55 ft lbs.

If the wrench is marked in inch-pounds, it won’t go to 55 ft-lbs. Look for a wrench with a 3/8” socket.

Your wrench is for things like bearings and precision light work.

Thank you. I couldn't figure it out it was used in the aircraft engine maintenance previously.

Only thing I know of on a Model A off the top of my head that is spec'ed in that range is pinion preload at 20 in-lb.

Yep, so don’t toss that wrench because you can use it for a rear end overhaul.

Thank you all. Won't toss it as it was my Fathers he was in aircraft engine maintenance.

There are some semi-decent import beam-type torque wrenches out there in that range, but a good dial wrench in that range will set you back a mortgage payment. Please hold onto it, or sell it to me.

I've got all sorts of torque wrenches 1/4 3/8 1/2 being 3rd gen tinkerer. I just picked up this little adapter to toss in the tour tool box. https://www.harborfreight.com/12-in-drive-25-250-ft-lb-digital-torque-adapter-58706.html

I don't think I've ever seen one with that range (24 inch lbs.) that wasn't basically a screwdriver.

Randy - CDI Torque (now owned by Snap-On, so you know what that does to the prices! But they're down in your neck of the woods - City of Industry) has several dial-type torque wrenches ranging from 0-15 in-lb on up. I have a couple of CDI ratcheting type that I got from Grainger years ago and they're quite nice. They have rebuild/calibration services as well. NIST traceable if you need it.

This is what I was thinking about in my previous post. Apco Mossberg made several ratings of these, starting at about 6 inch-oz and up. (55 ft-lbs would be even more out of reach!!).

If it's the type that Randy show's in post #15, this won't work, if it's a typical, common type torque wrench, try this: https://www.mountztorque.com/calcul...tmu1QOm6rnzSJHYd_iWbWrsfUNSAl0CO6MJulJ5hkCLv1

Small screw sizes up to 3/16" are in that range. My old dial in/lbs torque wrench has a range of 0 to 600 in/lbs. The average one hand with a srew driver will get to 14 or 15 in/lbs.

So good practice is to use a torque wrench more or less at mid-scale to get the best results. Let’s say that OP would use his 0-24 in-lb torque wrench at 18 in-lb to get to 55 ft-lb, and that the torque wrench is 6” from handle to the pivot point. Using Katy’s formula, 18 indicated in-lb would need a spanner extension of about 214 inches (almost 18 ft) to get to 55 ft-lb. Kinda tight under the hood for that, methinks.
