I'll bite...how does it work?

And one installed on a 1480 1/2 shaft -should hold up to 8000 ft-lbs-were starting at 5000 and working ur way up if it limits too soon- Jess

Synopsis: When you exceed the rated torque of the limiting bolts, they break. The bolts cost $100 for three of them and the shaft is retained even when the bolts break. Yes, I read the pirate thread.

 

[drivelineman]

its a accurate device that will limit torque by the sheer in the special bolts they supply-it does hold the shaft together after it sheers-it will not flop around- available from 2000 ft-lbs to allot like 25000 hehe - Jess

Sweet mother of GOD!!!

 

[chevyfumes]

Nice...

 

[drivelineman]

these are all custom made at this point the flanges were made in house -the weight on these was 50 lbs- they have a beafy feel when you pick them up- Jess

So its kinds like the rear brake rotors on freestyle bikes ? The unit is made like a unit bearing kinda , top and bottom rotate independently of each other until bolted together ?

 

[drivelineman]

here's the fancy little bolt there are three- Jess

Pretty good idea. I've seen these used for years on PTO driven shredders and other types of farm/ranch equip. We used a PTO driven drag behind shredder all the time on the ranch. Always had to replace those "torque fuses" when the blade of the shredder would catch a log or somethign else hidding in the tall grass. Finally about time they start using em in the auto world.

Those are the same style limiters as used on Frac pumpers on the driveline between the transmission and the pump all behind the 2250hp diesel V12 you bet they work.

I was reading an article on Suicide Sally while waiting to get my hair cut a couple months back and they were talking about this then.
Jess have you checked out the rear drive shaft on her?

Hhmmm used to have to crawl underneath a 10 wheeler at spud harvest about twice a week to replace those things. They look a little different but same idea

 

[BL1TZKRIEG]

I've seen those for semi trucks
awsome idea

 

[MattK]

they had these in one of the 4x4 rags in the last few months. they called them torque fuses in there as well.

 

[muddybuddy]

whats the starting price for one of those driveshafts? looks like beef

 

[drivelineman]

These driveline's are for sand cars- there 1200 per side- Thanks for the input - They are used allot on semi truck and ag stuff- Jess

 

[fireplug]

Same idea as the Warn hub fuses then.

 

[drivelineman]

sort of but i think more workable-and accurate- Jess
