450lb torque

[Floyd D. Fitzgerald]

ok, all the posts contained some funnies, and I had some laughs.
But seriously folks, how was the torque really applied?

What tools did service shops have? what does the manuals say about doing this?

I have tried to put all the force I can on my try at this, and am sure it was not enough.

thanks,
floyd

Floyd........as was said, you CANNOT over torque that BIG-NUT ...but... the consequences of under torquing is having to replace yer 6-spline HUB is a PITA. $60 (not cheap) You haffta have yer tractor ON-the-GROUND to apply that much torque. Iff'n you don't think yer torquing enuff, figger out a LONGER handle, that ALWAYS multiplies yer applied effort. Some ol'geek called Archimedes is reputedly to have said: "Give me a LEVER long enuff, and a place to stand and I will MOVE the world", or sumptin to that effect.

The NEED to torque that BIG-NUT is REAL. 450ft/lbs is what it is rated. Only the sphincterly challenged goes out an rents a 600lb torque wrench. Ennythang from about 400 to 500 ft/lbs is close-nuff.........Dell, the non-challenged

Most shops used a 3/4 inch torque wrench 4 ft long.

Long lever, hang weight on it is the way for most of us.

That said, in the close quarters of a Mazda RX7 (Hummmmmmmmm) transmission hump, where a long lever is difficult to use, I saw this contraption being used to get 350 lb-ft on flywheel to crank nut.
Looked pretty well built & the fellow said he had made & sold a few.
Many ways to skin a cat.

A shop would have the correct torque wrench for the job. Ya common man will not own one but a shop would because they would also need it to torque the head bolts on a diesel and a lot of other things

Floyd,

I think you misunderstood some of the replies. Yes folks were having fun, but they were serious too.
Start with your tractor ON THE GROUND
Get a long handled socket wrench, breaker bar, combination wrench, or similar
Weigh yourself (for the math below, I weigh 215, replace your weight where I inserted 215)
450/215=2.09
Soooo - You slide a 2.09 foot long piece of pipe (roughly 25 inches) on or over your wrench and put all your weight on the end of the pipe, or use a longer piece of pipe, and put all your weight at 2.09 feet from the nut.
This dosen't need to be exact, so if your pipe is off an inch or two, it's not going to matter.
Follow?

Floyd - as I said - get a 2' long 2" combination wrench and hang off the end of it. I found a cheap one for abour $35, but it works just fine and I only use it for this purpose. Don't just tighten it once, tighten again after driving around, then again, then again, THEN AGAIN! Keep putting torque on it until it does not budge after driving on it a bit. Put the lock ring on it and you are good to go.

Thanks, Paul
