I disassembled the main pump and found nothing wrong, then I pulled the right final drive and found the lining worn off one side and had been filling on the plate,,this is where my grindings were coming from,,I checked the left side and it was worn down badly. A combination of a heavy tractor and a big slitter planter,along with a bin full of seed,,mixed in with Southern Ohio hills is probably the cause. We don't realize how much the brakes on a single axle are put to the test like this.

Hummmmm ? Now didn't I remember reading about you running some aftermarket brand of hyd. oil ? Just wondering if you knew for sure what brand oil this tractor had in it ?

tim s · Oct 6, 2017

Oh yes it's Castoil, and the brakes actually wore out from being over loaded on the hills is what I'm thinking. We have used Castoil for 25 years in the other dozen Deeres with no problem, I am solid on using it for sure, 2-4020's a 3020 4240,4440, 8230,2-8330's and 2-9400's this is the first brake issue in those 25 years. The big splitter planter this 8330 pulls is heavy, and I am sure it was moved on the road a few times with the seed tank full..and we have a few serious road hills in this area. as you can see on the other brake it is worn down a lot..Bad or wrong oil will let the brakes deteriorate, this is not the case in this repair, I am sure there are other oils that will work, but other than Castoil #20169 in 55 gallon drums, and #20167 in 5 gallon pails I am not sure of the others yet,,Deere does not own a refinery,,and there are other oils out there to match Deere specs,,,maybe others on here have proven which ones they are, it can be a costly experiment, for sure, and 25 years of successful use has proven this oil to us..now if I can just get my little brother to gear down on some of these hills.....

Still I have to "wonder" if hy-gard would/could of helped it ?

Might be time to hook up some sort of brakes on the planter ?

I truly think that this oil is as good or better than hy-gard..When Deere designs their equipment they try to get a good cross sectional view of all the terrains involved,,On Hill country roads the strain on the brakes is far greater than in the normal areas. Years back when we first started to use a large grain cart behind an 8640 we soon found out that you don't bring a cart load home to the bin site,,a 30,000lb. tractor and 800 bushels of corn plus the cart weight on one axle of brakes did not work out,,on that set up it would bow or dish the brake disc,then eat up the perimeter of the linings as they failed. I should have went to the brakes first on this job, but when I did not find lining in the sump screen I went to the main pump instead,,turned out as the brakes were actually wearing down instead of deteriorating the small particles went on through the sump screen. And again I am posting all this to share what I learn as I go....

That's why those JCB fast tracs got so popular as they were set up for the road and the carts and tankers they pulled usually had brakes.

Surprised your suction screen was clean.

So was I,and I checked that first ,of course,, that is one reason that I inspected the pump,,it seemed that since the linings were "worn" down instead of deteriorating that the particles were small enough to go through the sump screen. The filter system on these are very good so it captured these particles before they could get to the rest of the system. I weighed this tractor before I put the duels back on and it weighed 26,660lbs. no fluid in the tires,,I'm not sure what the planter weighs, but it is a lot to ask of one axle of brakes on these Southern Ohio hills.
