I'm in the planning stages of building a llss tractor. Ih 460 sheet metal, dt360 alcohol motor, very light trans, tube chassis. Where I'm up in the air is on the rearend. The 560 rears make me nervous with all the problems they had. I have access to an 806 rearend and trans housing but am not sure if I can lighten it up enough. I have no problem milling the housing out to lighten it up. My local club has a 6500lb limit, but I intend to travel and will have to make a 6000lb limit at times. Trying to keep the tractor as light as possible and have as much moveable weight as possible. Obviously has to be heritage ag based but I am willing to go newer if that is a better option. Light and strong. Options? Thank you in advance.

Since you are just planning I would look into a 885, 895 or maybe one of the maxxum rears, personally I don't know how strong they are but it can't hurt to explore every available option. Your personal wt might be a limitation on a 806, I know they are comparably heavier than the 560 and it takes a significant investment of time to make one work. It can be done but it is difficult enough that I would look into several different options.

I definitely agree with George, as long as your rules say you are allowed to run the dt360 in front of the 895 rear! I went through this along time ago. I was not allowed to run a 360 in front of a 560 rear. I am now allowed to do that. But I had to get billet parts made in order for it to survive. My guess is you'll have to do the same thing in the 895. But at least it will be newer than mine.

Newalkyholic Registered: 09/13/2014 Posts: 155	I was just kidding about calling me fat, but I am well over 130! Add a hundred pounds to that! That's the input I'm looking for so thank you George. Trying to avoid costly mistakes so I'm researching whatever I can. Thanks to all who have responded so far. You have no idea how much I appreciate it. Reply Quote

Red llss	No mater what IH rear you use you will need to run a billet carrier now or later once you start to make some power and hook it to the ground 560 has a stronger trans most running the 656 have went to the pro fab to hold up Reply Quote

Newalkyholic Registered: 09/13/2014 Posts: 155	Yes, the trans will be aftermarket and very light but strong. At this point I see the rearend as the weak link and I would rather spend the time and money to do it right the first time so I can spend more time pulling and less time wrenching. Reply Quote

Brad 1206	If you are going to put a after market trans in, have a good set of bull pinons made and a billet carrier. Should be ready to go in a 560 or 656/666/686, once the work is done both seem to hold up well. One thing about the 560 is the bigger bell housing so you can use a larger clutch disk and easier to get a 4 disk clutch in. Reply Quote

Newalkyholic Registered: 09/13/2014 Posts: 155	I've heard that the 560 rear is actually heavier than the 656. Is this accurate? What size clutch fits in the 560? 11 inch or 12? 656? 666? Thanks guys. Just trying to do this right. Reply Quote

I have been told that the 656 is the way to go with a 350 center section. The 350 center section is not casted for the live hydraulic pump and is much lighter. You have to run a smaller flywheel with the 656 or 350 center section. Degenhardts ran that setup in their old tractor. They ran lss and hssd with the 656 rear end and 350 center section. I think they even pushed that setup with 3 turbos. So whatever clutch they ran would hold the power you should make. I was even told that they had stock gears in that tractor with the constant mesh changed to speed it up. Just my .02, good luck with the build! Beer
