Hay maker2 Calling all 4020 powershift experts! 11-04-2015

I have a question for Hay maker2 on the forum posted on 11-04-2015. I have a 3020 powershift that has the same symtoms as your 4020 powershift and I also thought repacing C1 drum sealing rings,piston packings, going through control valve/shift valve housing, check sump screen, new filters and oil would bring up C1, C2 and PTO pressures from origionally 50 psi. but only came up to 60 psi and PTO is 150 psi like all the other elements now. My question was did changing the manifold fix the problem? The last of that forum was you had changed C1 drum and that brought your pressures up to 110 psi and you stated on that last post you were going to change the manifold next. I am going to change C1 drum and the manifold also and hope that will fix problem. I was a John Deere Technician for 28 years and never had that problem but everything is getting older and more wear on things just like me. Thanks Troy

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o ... [Read Article]
