  • Torque
  • Anyone know the specs for what the lug nuts should be torqued for both front and rear wheels on a 54 NAA? I always just torqued until it felt right, but in my old age, I'd like to be more accurate.

  • I don't anybody who actually torques their lug nuts on. I use a 6-PT socket wrench to snug up and final pass is with a breaker bar -not a 6 FT fence post, a short pie (cheater bar) don't overtighten. To answer your question, front wheel studs lug nuts are 1/2-20 NF to 120 ft/lbs and Rears are 5/8-18 NF to 240 ft/lbs, both Grade 8 spec'd. Has nothing to do with the wheels. Torque is the value set by material and size for any fastener. Torque is a term often misunderstood and overused. Many do not know the proper method of torqueing a fastener. It's done in three steps, not all at once. Many do not know the different settings; there's inch-ounces; inch-pounds; foot-pounds; Newton-meters so know what you are dealing with and how to convert each. You really want to do all that for lugs nuts? A little better than hand tight is sufficient. You might be amazed to see how close you can get with your hands first then check with a torque wrench. Your tractor, your call.
