Draft-control valve replacement fixes all kinds of things

[RegL]

I talked to Terry this morning. He confirmed something Carl mentioned up thread, which is that they dropped that charging-valve filter in 2010 -- the same time they switched to the new version of the draft-control valve that they put in. So I think all this rigamarole probably doesn't apply to a new 1430. He says that replacing the filter shouldn't require bleeding, but that if I ever DO want to bleed those circuits I should crack the port on the bottom of the charging valve. Sometimes, that's just a port, sometimes there's a hose on it. Just crack it and then tighten it back up again (essentially the same thing I did, except I did it at the draft-control valve). Finally, he said that the nipple I highlighted in the picture is NOT the place to bleed it. That concludes my report.

Nor the old 1430's. Isn't the charging valve for the brakes. The 1430 does not have hyd. Operated brakes or tilt seat. Has draft control but no filter in its circuit.

I think the poor old charging valve has kinda become the all-purpose source of hydraulic lines for odds and ends over the years. Looking at those 1850 hydraulic diagrams that Carl posted a while back, that charging valve is in the circuits for:

- brake tender
- brakes
- steering
- draft control
- PTO

So a lot of things are interacting, all at the charging valve.
