cumbres 09-03-2012 18:44:29 70.169.116.230 Report to Moderator	I have a leaking outer seal on the right side. Read the nice write up found on a link here. Read the manual. Everything seems within my abilities as a shade tree mechanic without a lot of courage, except for one thing. That is the the spec calling for 450 foot pounds of torque on the axle shaft nut. The biggest torque wrench I can find stops at 175. Is there an old timers (sorry :D ) trick to make the 175 foot pounds wrench work for the 450 foot pound spec? Also, any other tricks I should know?

For the believers on just weight.... Loosen the lug nuts on your car/truck lay 100lbs on the end of a ft bar to tighten the nuts then go drive it... Make sure you insurance is paid up.... Typically, 80% – 90% of the input torque is used to overcome friction in the threaded and underhead regions leaving only 10% – 20% of the input torque left.... That being said i would venture to say it would take at least 600lbs of weight to achieve 450 ft lbs of torque... Nutter shock :shock: The same apply s when you are re-torquing your head bolts,,, add 10 to 15% to the torque setting to achieve the desired recheck of torque... I have never seen this apply to a N head bolt tho... All I have ever worked on the bolt turned (torque overcame friction) before the desired torque was meet... TO check actual torque on a bolt that has been torqued accurately it takes dedicated expensive equipment anything else is just a guess... The equipment must be able to measure the instant the fastener moves and at what torque it took to move it any thing else is just a guess... [Reply]  [No Email]

I had checked with the autparts stores and they didn't go that high. I will try the cheater bar and my more then 200 pound weight with a bounce to finish the job. Thanks! [Reply]  [No Email]

No way I trust using just weight on a bar to do the job its not going to tighten it to the correct spec (NOT EVEN CLOSE) if you think so you are smoking some good chit.... [Reply]  [No Email]

If you're really hung up on numbers you can buy a torque multiplier to go between the socket and torque wrench and multiplying your torque wrench reading by the factor the multiplier does. But I'd get the big pipe and known weight and save the money for a welder or something else you'll use more. [Reply]  [No Email]

I weighed myself. I divided 450 foot pounds by my weight, and made a mark on the black iron pipe at that distance. I hung on the pipe with all my weight, holdign the pipe at the mark I'd made. Voila, 450 foot pounds. [Reply]  [No Email]

Those axle nuts need to be checked once in awhile. while you are there, might as well check the prices of the 3/4 drive 1, 1 1/16, 1 1/8, 1 1/4, 1 5/16' sockets. around old tractors, you need those too. with tractors, I don't have much luck with the 1/2" drive stuff to break loose old parts. even the good 1/2 ones break with 4' of pipe on em. BTW, don't ignore garage sales. I picked up four 3/4 drive one inch plus impact sockets, and a half dozen plus 1" wrenches for a buck apiece. Guy said no one wanted the 'big' old stuff [Reply]  [No Email]

Some "rent" the tools, like AutoZone if they had one. They charge you purchase price then give your money back when you return it. Otherwise I've been told that 100 pounds on the end of a 4 ft bar is close to 400 ft/lbs. YMMV [Reply]  [No Email]

I don't mind buying tools when I need them but would rather the $$ went to a nice mig welder instead. Much more needed tool. [Reply]  [No Email]

No dice on stretching that 175ft-lb wrench to 450. You need a longer, thicker, and larger drive (storey of my life :lol: )wrench to torque that after you get that seal fixed. They can be pricey. Might check out HB for cheap wrech. [Reply]  [No Email]
