860 vs. industrial flywheel

Anyone know how to identify a Red Tiger flywheel? The one from my 134 industrial is different from the single-disk flywheel in the 2000, so it MIGHT be compatible with a double-disk clutch in an x60. Would Ford have had 3 different flywheels? The timing numbers are easy to find and clear, but I haven't found a part number on it. That would make it too easy. I can grab some measurements after milking.
This would be a good one to use, IF it's the right one - it had a drive hub bolted rigid to it, so there is no wear on the face.

12" across the face
1" from the face to the ring gear
2" thick
15/32" from the face to the bolt flange

Hello FordFarmer , The Five speed live pto flywheels are completely different than four speed and five speed flywheels and 100 series are different than 01 / 1000 series flywheels. Most Industrial engines use 100 series tractor flywheels but not all of them some are Industrial only . I have never seen part numbers on them . All 100 series tractors 1954 - 1957 use the 1/4 inch or so spacer plate behind the flywheel and the flywheel is thinner about 1 1/2 inch or so . All 01 series 1957 - 1962 and 1000 series 1962 - 1965 use the thin spacer plate behind the flywheel and use the thicker flywheel about 3 inches thick . Both five speed live pto flywheels are are dished and have no machined surface for the disc but are different thickness by about a 1/2 inch and will not interchange with each other . The combination you think might work will not work whatsoever with live pto clutch setup . As to your question about 3 different flywheels after 1959 you have S.O.S. flywheel , 4 and 5 speed single disc flywheel and 5 speed live pto flywheel , and to further complicate things 1957 and early 1958 01 series coarse spline tractors used the 100 series flywheel and clutch . What exactly are you trying to do ? Thanks Tony

Thanks for the info, Tony.
There's a guy looking for a flywheel for his 860 (his
post is on page 2 or 3 now). Was hoping this
flywheel I have off an industrial would work for him -
I would get a few bucks for it, he'd have a cheap
flywheel.
