I was bending bars trying to to loosen my lugs and some just would not budge on my M35a2. I able to acquire a calibrated 3/4" torque wrench that was due for resert and I increased to setting until the lugs came loose. It was in the area of 600 - 650 ft. lbs. Twice as much as the required 325 to 350 torque the TM says to have. By the way, the torque wrench was recertified without needing adjustment afterward. The Maintanance unit that did the last service must have used a 1" impact and ratteled it for some time to get the lugs that tight. I'm glad that I did not have an issue on the road, like a flat, I would have been there for awhile and the cost, don't even think about going there.
I got a 3/4" ratchet wrench off the internet that is 24" long but will extend to 41", along with 3/4" extentions and a socket that does both sizes, also got a electronic torque measuring device, 3/4" male on one end and female on the other. Had it checked for accruatcy and it was only off 1 ft. lbs. at 350 ft. lbs., good enough for me. I try not to get stuff from China but for something that will sit in the Duece's tool box until its needed and the price for all of it at $200 give or take. Just having to get a 3/4" torque wrench is a heck of alot more than that. Its good insurance along with marking the lugs to see if there is any movement.
Got all the "stuff" from that site that starts with a "E" and ends with "y" did I do that?
Hope this info helps someone.
