Rear PTO question

946 Views 5 Replies 3 Participants Last post by  oleboy
A while back I was using my 140. It has the (under 30,000) rear PTO installed. There was nothing being ran by the PTO at the time, when for whatever reason the round shear plate disintegrated.

Closely examining the round shear plate it looked to be possibly made of 1/16" spring steel. Not having anything on hand to fabricate one, I pulled a scrap of 1/8" aluminum sheeting out of my bag O tricks and fabricated a new one. My figuring the use of the shear plate originally being steel, and the added thickness of the aluminum would have near the same shear factor considering it's use. I'm somewhat skeptical even though I have the PTO back together and balanced.

I'm looking for feedback, thoughts and experiences from others who have done what I have?

What you are calling a "shear" plate (I think) , is actually a "Flex" connector , that is designed to relieve - or quell - any minute mis-alignment between the two shafts . It will automatically adjust itself to account for any settling in , from time and gravity forces that occur . As long as you have it centered , I don't see the harm in the connection , being what it is . That being said , just keep in mind that any slight frame twist will stress that joint . If the mounting bolts for the plate are rubber isolated (which I think they are) , they very may well be enough to allow a little frame flex , without any concern or worries .

I could be wrong , but I'm pretty sure the "new" revised by Deere "FIX" , unit will a fiber , thin flex connector .

Keep an eye on it . Some manufacturers (Simplicity) used a thick rubber joint connecter to do the same thing .

Good luck , and if you are worried about it , you can still buy the new Revised fiber item from Deere , or on the used market . I've seen them advertised on eBay and I'm sure some members here could fill an order as such , also .
