Hose size for toplink cylinder?

Zebrafive · Feb 16, 2012

Make any difference what size hose I use?
Cat II 3pt. 3" cylinder. As short as these hoses will be cost is not the deciding factor.
So 1/4", 3'8" or 1/2" ?

I have 3/8 and it is plenty.

I would use the 1/4 inch hose in a effort to slow down the flow of oil so the cylinder wont move too fast. I would also install flow restrictors in the lines if I could find some. I had no luck finding any locally the last time I wanted some.

1/4 in hose and a needle valve.

My rear SCVs, JD deluxe 301 series made by Husco, have built in flow control. Will that be enough with 1/4" hoses?

Probably. Connect up the 1/4 in hose and try it.

My JD 3rd SCV kit has the huge back hoe quick couplers, not sure on the hose but is definitely bigger than 1/4". There must be some type flow restriction in the system somewhere cause it doesn't move to quickly, very much in control. Could just be the cylinder.
When I hooked up a truck's snow plow to the rear remotes, even though they have 1/4" fittings the plow moved so fast I could do an NHL slap shot!

If you want slower hyd, you can reduce engine rpm.

Install orifice restrictors in the hose fittings. Washer with a small hole in it.

Install needle valves. Surplus Center - 3/8 NPT 8 GPM PRINCE WNV-600 NEEDLE VALVE

Some hyd valves have flow control built in.

If you have the bucks/dollars, you can use solenoid proportional valves.

Mine are 3/8" and I should of used 1/4". I'm putting a needle valve on it to slow it down.

I have flow restrictors, $10 ea + shipping. Install right behind your male quick connect end. 1/2" pipe thread.
