Auxiliary hydraulics line question.

Postby J3 Driver » Sun Oct 03, 2021 6:32 pm

We added a valve to my son cub for an auxiliary hydraulic circuit.

I’m getting ready to get he hydraulic lines tomorrow and am going to go with 1/4” hoses.

I noticed the port that I tap into is 1/8” NPT. Will I be ok going up to 1/4” for the supply and return line from the valve to the bypass block?

Thanks in advance.

Yes, no problem there. Is there a relief in the auxiliary valve? You'll want that. If so I'd back it all the way out. If it's cranked in all the way, it could cause the pump to dead head. Once you have everything working, you can bring up the pressure as needed.

Looks like a nice clean installation!! :{_}:

Thanks
Yes this valve has the relief built in. I wanted to do hard lines but I’m not that good at bending tubing and hoses will be easier I think.

I scratched my head for a while trying to come ion with a good mounting place that I wouldn’t have to drill any holes. Any mods I do I want to be bolt on and off. This was the best I could come up with.

What are you planning on running. I would think the hydraulic pump would be so small it would lack the capacity to have much speed and that you couldn't really run much beyond a lift or tilt. Also fluid capacity without a reserve tank is small and would get hot quick if worked much. I'm definitely not a hydraulics expert but those are my thoughts.

Just a plow angle cylinder. I’m using a two way cylinder so that when fluid is pulled out of the touch control unit it is replaced from the other side of the cylinder.

Don't worry about it. Members have run far more than a simple angle cylinder off the factory hydraulics. Is it 30GPM? No but it will do plenty of things if you aren't in a huge hurry.

I made a mount for the valve that was sandwiched between the steering riser and the torque tube,everything is theoretically removable . It's all in this thread- http://www.farmallcub.com/phpBB2/viewtopic.php?t=15998
