Shed cleaning find

[Sparky-(Admin) 22,112]

Rearranging the shed and the garage for winter. Came across this. 
  Anyone know what model it fits? Seems small for a C series.

I bet that is a C series bell… unless those ones are 6-1/4”?

107900 is a idler, 102900 is a wheel.

Seems like the "old style" PTO clutch face. I don't know the exact year range, but the older (maybe 1960-ish to 1973?) used a smaller diameter PTO. I may be wrong, but I think everything after C-series used 6 and 1/4 inch.

Maybe it’s for the 8HP units? B-80’s and the like. Smaller HP = smaller clutch face??

Just got a replacement clutch face for a 1972 Commando 800 (8 HP ) and it measures 6 inches .

Yes but the early PTOs were smaller in general. 

 

Old style on the right below.

 

Both my Bronco and a couple Chargers I've had came with these on them- I assume as replacements for the electric PTOs by a previous owner. This is also the size that was on the older PTO kit from the 60s.

Looks like the early 4365 has 6 rivets
