I have a Park in-lb beam that I use for checking pinion bearing preload. Unfortunately, Park no longer offers it.Always use mine for setting up pinion bearing torque.
I use mine to check the split beams on occasion. So far so good after a few decades.
I’m with these guys. I have one, and that’s exactly what I use it for.I have 6-7. The smallest goes up to I think 60 in oz, and the largest goes up to 150 ft lbs. Most have permanent +/-2% accuracy. I do use them as is (or along with a ratchet adapter), but I mainly have them for periodically checking the calibration of my clicker torque wrenches. Without being able to do that myself, I would have a lot less trust in my clicker torque wrenches…


The Plomb was made by Sturtevant. That is their logo on the back, but their name was left off.I have a Craftsman I bought new, probably > 40 years-old, and still have its box. I also have a Plomb. The Plomb was bought used, I suspect it's older than the Sears. Model 5403 Plomb, made in USA. A 'cool' factor is the 1/2" drive on both sides of the head, so you can have a good line of sight in using it where otherwise the tool would be upside-down. That's useful, versatile, and clever.

Me too and bearing pre-loadAlways use mine for setting up pinion bearing torque.
I find that every one of these "who still uses..." threads are started by people who don't do enough of their own work to need them.
