Hi, I have a 1540 with the same thing, the dealer come and looked at it when i first got the tractor, and said it was just air not worked out yet, my tractor also seemed very weak on the loader capacity, i hear the squaling often when turning or operating the loader, my steering also seems kind a weak turns hard sometimes sitting still with no load on the loader. Dealer never did say what to do this was a yr or so ago. I turned the the pressure relief valve up some to where i think the loader should operate, and now it performs nicely, it wouldn't even pick a bucket full of dirt up. And this loader is suppose to be rated for 2,000lbs. My loader also acts jumpy sometimes,and when you dump, it just sort of flops down and then a few minutes later it will dump all the way, it has air in i no thats what it is but why???? It just sounds like it surging all the time. So if there is a problem and a fix for i would appreciate info on this.


Thanks

Ryan

Hi, well i hope they don't find out about mine might be frowned upon. The dealer checked the pressure and i also checked it myself, it was up to spec but it still wouldn't pick up a bucket full of dry dirt out of the pile, unless you backed up. The manual don't show anything about the pressure relief valve, but i just graduated as heavy duty truck mechanic , and i have helped the mechanics at the coal mine i work for, and i am the neighbor-hood equipment mechanic as a side job, so i figured i could figure it out. (Sorry about the background info, just wanted to make sure no one thinks i have no experience with this stuff) The valve is on the right side (sitting in the seat) under neath the joystick valve, it has slot for flat screw-driver, and a lock nut to hold it. I could turn the screw while it was on the tractor (paint was holding from turning) So i took the nut and all loose and unscrewed the whole thing and don't it on the bench where it was easier than on my laying on my back. ( It has been awile since i done this, my memory not the greatest)

I don't know how much i turned it or what pressure it is at now, i just turned it a 1/4 turn at a time then tried it until i got it where i wanted it. It will just start to pick the back tires up now, with oversized R-4s loaded, with 800 lb blade on. I hardly ever push it this far though.

If anymore question just ask.

Just be careful when doing that, its very easy to blow seals and cylinder packing's out of the pistons with to much pressure, or blow a worn or chaffed hydraulic line. I am a fellow diesel mechanic myself. I have seen a few dump trailers blow the seals out the five stage pistons because they had it hooked to the high pressure side for a walking floor trailer. Just be careful not to damage anything, just my advice.

Thanks for the heads up Dennis. It is easy to tear things up in a hurry when adjusting and tweaking things like this.

I was advised MF has tried several different solutions, but nothing was quite upto to their satisfaction... sounds to me like they are still working on it.

Well i hope they find a soulution, i was using the tractor again tonight and it gets old having the bucket flop around and not hold a grade, and having this thing surging all the time.

if your experiencing hydraulic power issues and noise, try changing your external hydraulic filter. i have spoken to dealers who have had these issues, and they solved the problem by changing the original MF1500 series hydraulic filter to the hydraulic filter from the MF1400 series. this solved the problem immediately. something to do with the capacity and micron rating of the two filters.
