On a Dearborn 14-16 sickle rear mount, the in to out movement of the 3/4' square shaft is only about 3", with the down almost up to the weld to the universal which creates problems.
1. This option of a sleeve would not work as the Ford 600 is already 1 3/8". not 1 1/8"
2. The use of an overrunning clutch 1 3/8" female to 1 1/8" male, Would require shortening the square 3/4" implement female end to accomadate the extra length of the overrunning clutch.
3. I decided on the purchase of a completely new drive shaft, that came with a 1 3/8" splined shaft,with snap coupler, and the standard 7/8" X 3/4" rectangular shaft and mill it to the Dearborn square 3/4". This shaft comes with the plastic safety shield also eliminates the bolt on shield that kept the cut hay from wrapping up on the shaf t and shorten the implement end by 1/2".
A 4th option is to use the adapter I use on the Ferguson buzz saw 1 1/8" splined pulley. I cut apart a 1 3/8" splined drive shaft before the universal and welded a old 1 1/8" splined shaft. This created 4" more in length which required 4 inch extensions.
I also updated my 2N to a 1 3/8" splined shaft as that is what my buss hog requires.
