I need a way to torque a gland nut to 450ft lbs without using a torque wrench...

I know there has to be a mathematical way to do this by using thread pitch, nut rotation, and diameter. I swear I read a thread on this but I cant find it..

This is for a flywheel nut on my turbo VW that is oversized and I cant use a conventional torque reduction device/tool.. I would just tighten the hell out of it but I don't like to work that way..

I know there are some big brains on this site thats why I have belong to the forum for some time now, so i hope that you guys can help me out here..

Thanks
Joe

funny i found that same conversion site.. thanks for looking though!

I have that tool and it works great but unfortunately it wont work in my situation because the nut is oversized..

I think I might have to break down and buy a 3/4in torque wrench....

I might be oversimplifying this but isn't a ft / lb the force of one pound at a distance of 1 foot from the pivot point. If this is the case you could measure 4 1/2' from the crank centerline on a bar on your 3/4" drive ratchet and hook something like a fish scale (maybe - don't know if they go that high) and pull on the scale until you read 100 lbs. Thread pitch does have an effect. Finer pitches have more contact and therefore more friction to overcome and should need a slightly higher torque value to achieve the same clamping force I would think. Since they have given you a torque value, they should have already done any research necessary to the correct value. Clay

Before I would fork over $700 bucks for a wrench I might use only once I would check out the rental companies to see what they have in stock. Craftsman, S-K, New Brittan Tool and Die all want an arm and a leg for a gear reduction 3/4" 0-600 ft/lbs wrench. I can never find the Snap-On man, but I bet he wants your first born male child as well.

How about a VW shop locally? They must have a wrench in that size range and could probably bolt your motor to the bench and put on your fly wheel for you for less than the cost of the rental probably.

The easiest way I can say is using this method.
Scroll down to using an extention with a torque wrench.

thanks guys... I think my best bet is going to modifying my Torque-Miester (gear reduction) tool.. i think I might weld a 1 1/2in socket to it but Im not sure..


That gets me thinking is there a homemade tool sticky? there should be! some of my favorite tools are the one that I made...

i agree Idea . i have some interesting stuff myself. for example... ever try getting to those motor mount nuts inside the frame on the 80s-90s Chevys ? i cut a 15mm wrench in half and welded the boxed end to a short pry-bar. works great.

So you pry the nuts off? Laughing

We have a tool section for just such a reason (SMOKEmUP.com Forum Index -> Tools). To tell members about tool solutions to problems. Like Crow Foot wrenches for tight places.

i think he meant we need a sticky at the top of the Tools section so its easier to find.

well it took me 2 hours but i made my torque-miester tool work for a 38mm gland nut!

I used my 1/4in carb bit and my drill press to do all the machining.. Taking carful measurements I got a real nice fit that works great..

Thanks to all that replied. This was hell of a lot cheaper then buying a 3/4in torque wrench..+

nice work Cheers . are you saying you used a carbide burr to do that ? i would like to hear more about how you accurately cut that out. i still think a "sticky" on homemade tools is a good idea.

I agree with 10sec.et on that one, damn nice die grinder work!!!! Anybody that's ever used one a lot will appreciate what a good job you did. Good going. Clay

I just leveled the drill press and locked down as deep as I wanted to go. Then ran the tool by hand using a mill vise and taking measurements as I went...

I often use my drill press as a mill.. I'm sure that the shaft bushing will wear out soon but I can replace it...
