Changing baler hydraulic gauge/re-charge hydraulics

crzybowhntr · Jun 16, 2016

I have a new hydraulic gauge to put on my Vermeer 403F and would like to know what to expect when I unscrew the old one. Will fluid leak/spray out? If so, how do I re-charge the system? I`d like to have a properly functioning gauge for obvious reasons.

(quoted from post at 12:33:57 06/16/16) I have a new hydraulic gauge to put on my Vermeer 403F and would like to know what to expect when I unscrew the old one. Will fluid leak/spray out? If so, how do I re-charge the system? I`d like to have a properly functioning gauge for obvious reasons.

On my JD balers I have/had 2 hydraulic circuits: 1 operates the tie arm with no residual pressure if you shut off the tractor before unplugging the fittings and 2 operates the lift gate which also has no residual pressure if the gate is closed and the engine is off when you remove the fittings.

Therefore the only pressure would be static pressure generated by the atmospheric temperature being higher when you pull the gauge than it was when you disconnected from the tractor.

If in doubt, hook back up to the tractor, engine off, and cycle the hydraulic levers back and forth and then pull your gauge.

On recharging the system, like when you replace a hose or whatever, the tractor will do that for you. Hook everything up, crank the tractor, moderate rpm, cycle the hyd levers back and forth till the function operates.

Thanks. The new gauge is on but reads zero
when baling. Trying to figure out what to
do..

Any luck getting it fixed? I am having similar problems.

Call Carter and Carter in Tn. Long time Vermeer dealers. I am sure they can help you out.

For the others, this gauge monitors pressure on a closed hydraulic system on the baler. It is not connected to the tractor hydraulics. It is the pressure system that manages bale density. The gauge is used to select the desired amount of bale pressure.

On my current baler, I plumbed in at the distribution port just above and to the rear of the baler's PTO shaft monitoring the baler end ports on the gate rams, not the gate ends.

The pressure reads zero till the gate touches the baler and keeping pressure on the handle, pressure will increase to a few hundred pounds or so, till I let off ensuring that the gate has been thoroughly closed.....no latch on this baler like on others so pressure is all that holds it shut.

As the bale forms, the swinging arms (that move out as the bale forms) which are attached to the rams start pushing against the closed rams (shafts all the way in), trying to close them harder which develops pressure on the bale (to make it a tight roll) and if everything is perfect, will max out at about 2500#....the pressure of the tractor's hydraulic system. I'm using a liquid filled 5k# 2" gauge.

Clarification as edit function doesn't work: The monitor has to be on the shaft end (port) of the ram (cylinder) regardless of which end is connected to the gate.
