He means the five gallon bucket of paint finish.
Geeze tough audience! I never claimed I was a painter nor try to be , but all things considered it came out much better then the way I received it. LOL

Original Link To Rebuild Pics vs now with "5 gallons finish" , I'm not ass blasted by the finish considering no metal work to the hood was done and I didn't disassemble to paint a work machine not a yard princess lol

I would worry that swapping lines after verifying the schematic would risk doing more damage to the possibly failing pump?
I am just suggesting swapping the up and down boom hoses on the same spool, nothing radical in that.

Until you do that simple test or Tee in a gauge everything is just speculation.

The relief valve is tied into the pump IN side of the valve so if it had a problem every function of the loader would be affected not just lift and curl.

Thank you, Dave. I'll give this a try in the morning and see how it handles a 250lb weight in the bucket on both setups.

Looks fine to me, just not Kubota Orange and I like the painted hairpin cotters too.

Around here, 5 gallon finish refers to a backyard paint job, sometimes applied with a brush or roller. Usually refers to a paint job applied to a John Deere.

Lol ! Not butthurt just didn't know the expression. It was "out of the can" Krylon Fusion Popsicle Orange spray paint after grinding/stripping the surface rust and sanding to bare-ish metal where it was rusted. Not "Kubota" orange but it's close enough for me for a loader that sits in the barn to fix the driveway washouts and move firewood without continuing to rot to hell.

Why would that be? It would only change the direction the valve would cause the cylinders to move. The system does not care if direction of movement reverses.

Should not harm anything and might give some useful information.

A simple way to test the hoses being run correctly, break the fittings on the cylinders and wrap them with a good rag so they can not shoot out stream of oil under high pressure. Then with tractor idling operate the controls only enough to see what fitting is dripping.

Tested swapping hoses .... no joy .

Took a close look @ the belt and despite being taught it was worn on the sides and into the V.... tensioned the living $hit out of it and tested again... Full lift back!

Took it off which was a pain in the nuts and took to a hyrdo shop that came close enough with pitch but slighty shorter, adjusted the pump bracket and re-tensioned... lifts more than I should ever try to lift LOL


Thanks to everyone for their help... simplest thing.. Occam's Razor still applies !

Sorry but I'm not reading this to the end.

At first I was going to say champagne tastes on a beer budget but after seeing all that new paint and new hoses I'm thinking air in the lines. Did you purge properly?

Ended up being a worn belt. It was tight but slipping from wear on the edges and down the V.

Is your 3 point fully raised when you have this issue? I found my upper limit stop was out of adjustment, so with the 3 point fully raised it was pulling all the pressure and not allowing the FEL to do its job.
I figured this out by lowering the 3 point to about the half way point and suddenly I had FEL lift again.

Mine uses a separate pump for the FEL , it is not tied to the 3pt which is run off the hydro trans pump. thank you for the suggestion ! It ended up being a worn belt!
