4020 PTO oring

Mtractor · Sep 17, 2018

I have a 67 4020 JD that needs a new oring around the PTO shaft. I have changed the seal out but it still has a little leak and from the looks of it i need the oring. Whats the part number i need?

Look closely I bet the oil is coming from the actual rear seal, and when you change it you will also need the guide, it will have a groove worn into it the will make the seal fail..you can get the guide from A&I,,they work well..
