When I want to replace a swivel, the bearing is seized to the bentpipe when the set screw is tightened. Some techs tighten them, some don't. Then it has to be cut off with a cutting wheel to replace when it finally goes. With the WW setup, the bearing doesnt need to be greased or replaced. It's similar the top swivel block.
Tobacco's comments do cause me some concern though. Every 2 month's tells me that either it's an alignment issue, low/flat tires on his machine or the WW setup isn't any better. If it's every 2 months why not use the super swivel? They're all excessively overpriced, but if it's every 2 months surely a super swivel would last that long.
I have also run the double swivel and I must say that it does hold the bent pipe in place the best. But Mad, you said short swivel (way cheaper) is hard to come by and that it's what you ran on your doubles. But in my experience the short swivel won't let the bent pipe come down enough. I have to run the long swivel ($150) with the double to get it to work. Our distributor can and does keep the long in stock now.
Swivel...you are the weakest link.
