3PT Lift help

Hello,

I have an old 8n that I'm trying to use to do some plowing with. It looks good and runs well.

Last year I installed an auxillary hydraulic system that 'theoldhokie' put together for me. That works great, except I'm having troubles with my 3pt hitch now (and ever since installing the kit actually). I can no longer use the original touch lever to raise and lower the lift. There is an adjustment screw on the bottom of the diverter valve that I was using to manually raise and lower the arms, but that's not going to work for me with plowing this fall.

As far as I know, the auxilliary system should not interfere with the original whatsoever, it simply uses the original sump. The return line from the diverter goes into the top of the tractor just next to the shifter and the oil supply line just comes out of the bottom of the sump.

Is it possible that this is putting too much (or not enough) pressure into the original pump that the lift is not being actuated?

Thanks in advance for any tips!

ou have the name of the fellow that you ought to be asking.
 

I was hoping to find him here, I couldn't possibly look through over 4000 pages of user names though...
 
You should have been together with TOH the whole way through your project.
I asked TOH tons of questions throughout the process of installing my live
hydraulics.
He is your best bet to get it done right.

Hope that helps.

You should have gotten mine. You would have had it installed and using it in about an hour. 2 at the most.

Lots simpler and except for not having to take

your foot on the clutch the lift works just like it did.

Mine has no diverter valve. Doesn't need one??????

Mine is the original idea.

You really need to call me (should have done that long ago) and I will help you resolve your problem. Apparently you purchased a system with a provision for high flow remotes and a higher volume pump.

The internal 3pt control valve cannot exhaust more than a scant 3 GPM of flow - anything more than that coming in through the test port will generate excessive back pressure in the lift circuit and interfere with the normal control of the 3pt lift. That is why you have the adjustable flow divider. You can't run the bigger pump without some means of limiting the flow into the test port no matter who's system you buy. The screw on the flow divider is a one time - set it and forget it - priority flow adjustment that is used to acheive the proper flow reduction for the 3pt live hydraulics circuit. It is not to be used to manually actuate anything. So give me a call or send me an email and I will walk you through the adjustments needed to get your system to work properly.
