That's crazy talk if it was a shear wouldn't it be shearing something?I'm glad this thread was started now I see all the trouble everybody else is having with muffler bearings,thought I was the only one.Mine keep going out on my lefthand Skyhook. Anybody have any thoughts on this?

Start making righthanded turns only with your lefthanded Skyhook, it will spin the muffler bearings the other way. You will get another 6 months use out of them. HA

390 you're a lifesaver, I never would have thought of that I just hope it doesn't interfere with the rotator cuff splitter or the continueum transfunctioner on the cpu hooked up to the flywheel sensor.I'll let you know how it works out,thanks!

You should feel fortunate that you can even get a muffler bearing. I have had a machine down now for five weeks because they are on back ordered here at the local dealer. The flux compensated magnetic overload relay went out which caused all kinds of problem and took out the muffler bearing, not to mention the dicktorefractometer. Which is used to make the machine look bigger than it actually is for sales purposes.

a shot of the old glass hammer normally solves thet problem so long as the rubber nails dont crack!

Lonking. It's a shear. It cuts stuff.

Everyone else :)
I really wanna believe that these tensioning devices exist. I truly do and I can't laugh any more than I am right now :)

The real reason is the way force of the gold plated tungsten bearings in that rotation joint affect the machines stability.

You don't want to be around one of those muffler bearings when they go out. I have an uncle that lost a hand to a faulty muffler bearing

if you cleaned the pipes a little more often the muffler bearings might last longer....;)

For someone that is suposedly a manufacturer of heavy equipment, and excavators specifically, your knowledge of the product is excedingly narrow.

Everyone knows thats a deep pour concrete peir tensioner. They uses them to make sure that the concrete peirs for highrise buildings are properly tensioned. You wait till the concrete starts to set, and burry that paddle in the pour, rotate it, and that tensions up the concrete giving it the strength it needs to suport a highrise. Thats one of the larger machines I've seen with one mounted on, but it takes alot to tension up that much concrete.

Expensive... because of the quadruple reduction final drive that uses magnetic opposition bearings those units are super expensive, thats the rotation ring that you see at the top of what would be the stick. You can expect to pay a million us for an almost worn out deep pour tensioner unit, not sure what a new one runs but I'm guessing somewhere to the tune 10.5 to 11.2 million.

Not exactly sure on what a demo company is doing with one, they must also do some site work for when the new building goes up.

Hope this helped in your endevours longking...
