Yeah I definitely double checked all that! The hood fully opens, I can easily reach my oil filter and drain and pump. Yeah once the system is bled one should be enough, but I'm concerned about temps. Maybe I'll have to run an oil cooler.

What's the capacity of your upright? Piston sizes? I'm curious having one side would be easier. I'm going to be running a 6gpm 2500 psi pump to support my pistons. I'm worried about temps.

Never noticed overheating on my system, I also don't know the GPM of pump either, just know it works. :smilewink:

I'm thinking 6 GPM @ 2500PSI is overkill for a GT loader, and would be concerned about jerking movements, and slamming the cylinders.  Besides,hydraulics live longer at and below 2000psi. :thumbs:

I've been doing some research and I think your right! Going to go with a 4.5 gpm 2k psi @ 2k rpm and 2.5 to 2.7 at 3600 max rpm 4k. I will be running a control valve with an adjustable pressure relief. I'm going to start off with no oil cooler and see what happens. I will leave a place for one just in case.

You are really making some progress on it. I will note like the others that on my fel only one upright is the reservoir and no problems with the temps or running out of oil. My problem is I need a new control valve.

What size steel are you using for the uprights and arms and what thickness?

The uprights are 4x4 by 1/4" wall. The arms are going to be 2x4 by 1/8" wall.

That's some seriously strong steel you're using.  I used the same thickness steel for my loader arms, and not sure, but I believe thicker for my towers as well.  Better to go on the heavy side than too thin I say.

I was thinking of using 3 x 3 x 3/16 and 2 x 2 x 3/16 seems strong enough to me?

Lol! I don't want to worry about ever breaking! Those sound decent size. I would personally go with a 2x4 for the vertical strength on the arms.

I agree on the rectangular steel for the arms.

Pretty sure that those PF engineering plans use 2 x 2 for the arms.  I agree that you can´t build it strong enough though.

Have a small update. Work is crazy. Started the arms, I machined some weld in bushings today with steel outers and oil impregnated brass inners. I'm going to be using 3/4" sst bars for pivot pins.

I have the upper towers capped and opened up for the arms.

Now I'm waiting for the new pump and 4 spool valve to finish the frame fab. I also have to pick up more steel for the rest of the project.
