Brakes are the same size...

Also, even though there are small differences in several little places, everything will still interchange....I wouldn't be afraid to run the same 160 hp that a 1586 has in a 766.

I thought that they don't have as many plates or is that only in the wet brakes on the 86 series

2 plates and a floater same from 706 up ....... 14s got bigger brakes and the give away is the cast housing they ride in is larger diameter. LOTS of these parts will interchange 706 on up.

And that's exactly why I love these old tractors. I only wish companies would do the same now days.

I believe that the 766 and 966 shared everything but the engine.

I think the seven would handle as much power as the 806, 856, or 966 would.  Most of the time I had mine set so it would dyno around 135 or so with it's ears pinned back, but I usually backed the throttle off enough to keep the boost around 10 or 11 pounds, so figure I was using maybe 115 - 120 most of the time (?).  Not sure I'd want to try 160 for very long pulling a chisel or plowing gumbo.

Actually, if you dig into the rearend you'll find at least one bearing that I know of that is different between the two.  But not enough that I'd worry about.

The brakes are the same size but the 10 used heavy duty linings on the disks.  Fan blades, radiators, and water pumps were also different between models
