6530 Loader falling problem

[Willl]

Swap your lift/curl hoses with each other.

If it still drops, get your curl cylinders rebuilt.

If the dropping swaps to your lift circuit, get your valve rebuilt.

Hi,

I will try the hose swap.

Brian, the bucket starts falling when I pull up with a load of Dirt and get off the tractor to shovel the dirt into a spot. I have to keep going back and lifting the bucket to a position where the dirt will not fall out. An empty bucket falls without anything in it in a short period of time, just over an hour or so.

I believe that it is reasonable for me to expect the loader not to fall while I work unloading most anything in a period of 10 minutes, even longer. I have a pallet on the forks and it completely falls with nothing on the pallet in a hour or two. I say that this Mahindra loader is not up to par with most. I cannot understand it. I hope to try the hose swap and find out something.

Thanks,
Jirobbi

Jirobbi,
All of the tractor manufacturers, have an acceptable rate of drop, and the luck of the draw is correct. The other day I was at one of my customers, and he had his Mahindra parked in the garage with the loader up about 4 inches above his 4 wheeler. I told him I didn't think that was a good idea, but he told me he sometimes leaves it that way a week or more. Some leak down and some don't. At the shop I have the acceptable specs, and at one time, on TBN, I found a copy of the leakdown specs for a John Deere loader so I compared them to the Mahindra specs, and found them very comparable. I would ask your dealer what the specs for your loader are.

Jirobbi, just how far does it fall in that 10 minutes while hand(shovel) unloading. As far as it falling completely in an hour or two, I know that my 7520 would do the same if not faster. Now for the most part, I am talking about the lift cylinders, not the curl cylinders. As far as what Mahindra says is acceptable, those figures that I posted are straight out of the loader manual. Oh, those measurements are at the ram, so they would be significantly more at the bucket. If it makes you feel any better, I believe that John Deere's are even more.

On a side note, when we bought our Case 580E, we had to do some work on it. We had it in our shop and were tight for space, did misc things to it for over a month. The whole time the loader was raised up all the way and we had the factory block on the loader so the the loader cannot fall, but it was not down on the block. That loader never fell at all the entire time that we had it in there. Now why can't we get that quality on our AG tractors?

Because this quality costs a few dollars more. How many posts are there on here about people looking to purchase and crying about one brand being just a tiny bit more expensive than another. The American public asked for this, now they got it. Don't believe me? Ask the tractor dealers here how many sales they lost because the guy down the road was a few bucks cheaper.

Exactly!

I had a customer comparing one of my implements to one at Tractor Supply. Of course TS was less money, I said to him look at this machine, it is heavier duty and better made than the one at TS, and he replied to me I can see that and that is why for the same money you win. He bought the TS implement.

I guess that my point was that that type of quality IS NOT AVAILABLE on any AG tractor, JD, or otherwise. It seems that you have to go to an industrial machine before you really get the good equipment for a loader. Yes once in awhile an AG tractor is really good, but I do not think that is the norm. The spec tolerances are just to big I guess.

Pop the lines off the loader valve when raised. If it still leaks down too fast it's a cylinder issue, if not it's a valve issue.

Disclaimer: I'd only try this with an empty bucket else it will be a hussey to reconnect.

As others said most manufacturers have an acceptable rate of drop.
My 2615 bucket was dropping almost 2" per hour when I bought it. I was told up to an inch an hour was acceptable. My loader manual troubleshooting guide indicated an internal loader valve leak. The dealer replaced the loader valve with a newer updated model. It still drops with the new valve but would take several hours. I guess its the luck of the draw. Some will stay up, others will drop.

There are pilot operated check valves to add in line to the cyl, to prevent loader dropping until you apply pilot pressure by activating the valve. I think that even OSHA requires something like this when workers are working under one of these machines, for safety reasons.

I would think OSHA requires cylinder locks before any work is started. That is the way it works on airliner's flight actuators (cylinders).
