J.D 3rd. rear scv thread size

[onetotaltoolman]

hello- put in a 3rd. electronic scv on the rear of the tractor for esentially controlling the hydraulic top link.
The flow of the hydraulics is way to high, so i found a company callled " bolt on hooks" that has restrictors.
Problem? no idea what the thread size is. The J.D. product kit is called LLVU23912 which is a "rear outlet kit".
So, does anyone know what the thread size is of the rear fittings. I willl figure this out by taking them off and examing
thread size, but it would be soooo much easier if someone already knows that thread size they are. thanks to all!!!!

Match the restrictors to the hoses on the cylinder (likely less "exotic" than the DEERE side) and put them there.

Have you considered install a resistor disc(item 5) that contains a small orifice between hose fittings to slow flow to cylinder??

That would most likely work - where do you get the resistors? On the 3rd. electronic scv, the fitting between the valve body and the quick connect looks like it is a male x male O.R.B (O-ring boss) type fitting 3/8" in diameter.

Depending on the top link hose thread TSC, and likely others have adapter fittings with restriction orifices drilled in them.

ok - cool. Never thought to check there. I have a TSC fairly close. - will check this out.

One could drill a hole in a penny or dime then use that for a flow restrictor

This afternoon i took off the J.D. quick connector then the male x male connector that attaches the quick connect to
the actual electronic valve body. Looking in to the valve body, i was thinking the exact same thing. "bolt on hooks" has several of these adapters,
all say they have a .030 hole in them, but it does not look like they have an adapter with these particular threads. The "penny" could not make its way in to the actual valve, and lets face it, there is something to be said about the price of this upgrade,,,,,,,,,,,

I don't understand why you are unwilling to consider putting the restrictors in the hoses on the cylinder side of the couplers? You can buy little valves made for the purpose thar have adjustment knobs on them allowing you to "dial in" the flow you need to make the cylinder move as you want it to.

 

[onetotaltoolman]

that would work fine too. i have zero experience with that type of restrictor. Read a couple of reviews and the particular one
that this dude used did not work well.
Do you have a source or brand for them?

GOOGLE "Hydraulic flow control valve". Amazon has them, Northern Tool, most any hydraulic supplier. Need to check into what you may buy, many are "free flow" in one direction and adjustable flow in the other, you would need one of those in each line
