Howdy all,
I'd like to bounce a question off you guys for some perspective. My 3 point on my Ford 1700 works well. I have replaced hyd fluid, overhauled hyd pump and replaced lift piston seal ring. I just bought an oil filled pressure gauge up to 3000 psi and went to my place to check things out. My 3 point hyd system pressure pop off should be around 2300 psi per manual, but in reality it started popping off right at 1500 psi. I have no reason that my new gauge is off by 700 psi. Anyhow, the heaviest implement I pick up is my tiller @ 780 lbs, my Carry all full of tree trunk might be a hair over 900 lbs and the lift can pick it up with ease. I don't know what force it takes to pull a 6" wood post , 4 foot buried out of the ground, and again 3 point picks it up easy using my boom. My question is , should I even attempt to change the pop off setting and why. I don't have to shim the relief pop off as I do have an adjustment nut that can vary stiffness of the spring and it is a simple 5 minute job.
I tend to think raising the pop off is not buying me anything as long as I don't have to lift anything heavier than what I have already done in the past. I think it is best to expose the seals to no more than I need operationally if I can help it. Any pinions?
By the way , something else was puzzling to me was the pressure approaching zero as the 3point arrived at the height I intended. I know the feed back arm returns the spool to normal position(100% bypass to the reservoir), which at that point I still have an implement up in the air which the weigh of it should cause pressure in the lift cylinder. Reading zero did not make sense to me although there is no further flow when the lift system reaches it's intended height. Has anybody notice something like that?
