I am putting a different cab on my 4430. 1974 s/n
26??? so old style valve. This valve has three lines
coming through the firewall. I understand the
left/right lines for steering, but what is the third
line for?? Can I block it off?? The extra line's
source is opposite side of valve from bleed port and
about ten inches lower. Thanks for the help.

They won't mate up for you,,if you want to use the new style valve in the newer cab you will need to change the steering motor down front,,some one on here has one,,we were talking about it last week...or fit the old style valve into your newer cab....
 
Might be that John Deere put the line there cause it needed to be there. The line you are referring to is the hydraulic pressure for the power steering, as in no line, no power steering.
 
Larry it sounds like he has a new style cab with the steering brick out in front of the fire wall these take 3 lines to operate the steering brick(valve), then 5 lines down to the steer motor, they will not mate up with out making them match..

Why change steering valve? Steering valve & dash aren't part of a SGB(cab).

Update: I just read Ken Henry's other post where original SGB burnt so now I understand the need for different steering valve & dash.
