I have just rebuilt the SCV's on my 4430 tractor.
I installed all new valves, o-rings and back-up
rings. I adjusted each valve with the adjusting
plate. I backed the return valves off 1/8 of a
turn and the pressure valves at a 1/4 turn. The
clearance on the return valve is about .020 and
the pressure is about .060 so the return valves
open first. I installed them back on the tractor
and adjusted the rods. The #1 SCV is behind a
power beyond kit. Here is the problem. As soon as
i flip the coupler lever on the return side, oil
drains out of the coupler on the right side of the
SCV. I let it go for a little while to see if it
would stop and it didn't. The pressure side does
not to this. I moved the control lever back and
forth a little bit to see if it would stop and it
didnt. SCV #2 is fine. I adjusted them both
exactly the same. Anybody know whats going on? Any
input would be great. Also the when running the
draft lever the arms dont start to raise till the
lever gets to about the #4 on the console.
