Loader H130 Loader on 2032R "Drift" question

[Parkanzky]

I have a fairly new 2032R with the H130 loader. When I got it I tested the loader "drift" by raising the bucket to about 4' off the ground, shutting off the engine and leaving the tractor for the night. About 24 hours later, it had probably dropped a foot or so.

Yesterday, we were hauling log out of the woods with the forks. At one point, we had a few logs on the forks that I would guess weighed a total of 3-500# and we turned the tractor off while we did some limbing. When I looked back at the tractor a couple minutes later, the forks had dropped at least a couple feet. On a later trip out of the woods, we had closer to 6-800# on the forks and turned the tractor off to stack the logs by hand and if you stood back and watched you could actually see the forks creeping down.

I assume that JD has specs for this somewhere. I'd like to know the proper term for this settling, how it's tested, and what the specifications are for my loader. If not specifically for my loader, then what is typical? I want to run a couple of tests myself so that I understand whether or not there is an issue and where things are at before I involve the dealer.

John Deere has a table of leak down rates in inches/hour. I assume this is unloaded. Your dealer should have this info. The table I saw only went to the H120 and it was 2.82 inch per hour for the boom.

A few feet in a few minutes is probably well past their minimum spec.

The earlier reference of a foot overnight would be acceptable. The later...not so much.

First, make sure you have no leaks anywhere. Hoses, cylinder rods, etc. If all that is good, you have a valve spool that is leaking by more than it should.

Both of your data points seem like a lot to me. I have much less drift with my 4 year old 2320.

I have a call in to my dealer and they are digging up the spec (and the test) for me. I'll let everybody know what I find out.

Here is the chart from JD.
It seems like loader leakdown has got worse over the years. I wonder if it's because lo vis hydraulic oil is the norm now.

I had a similar concern with my 2015 JD 2032R loader drifting. So I did a quick test and posted it below. Does 7.2 to 7.8 inches per hour seem normal to you guys? On thing I have not yet tested is the bucket tilt drift. All I can say is that when I executed the test below, I started with the buck completely tilted back. After the 50 minutes was over is was tilted at least 1/2 way. Put it this way, if there was a load of gravel inside when I started, 75% of it would have been on the ground by the end of the 50 minutes. The tractor is to be serviced by the dealer this coming week and the plan is to ask them to test it as well. I apologize if the sheet below is hard to read as I pasted it directly from Excel. Apparently I am not smart enough to attach it as a .jpg. Thoughts, comments, concerns, suggestions are all welcome. Thank you! PS, if someone would like to post the .jpg please let me know and I will send it to you. It is much easier to read.....

Let me know what you hear. I took mine to the dealer and they said that those specs are for the cylinders and is not a measure of how far the loader arms fall or how much tilt there is. So if the cylinder extends that far in an hour, they'll do something. In my case, they passed because there is not a lot of movement in the cylinders to drop the bucket a long way...
