ok i got john deere 1050 tractor with a loader on back hoe on it and the hydraulic system has water in it i'm draining it all and getting a new filter anyone know ways to keep this from happening??? and also i found a john deere 301A tractor with a loader on it locally for $4800 it has new tires and a rebuilt john deere motor with john deere parts think it's worth $4800???

 

Condensation from heat in the cold after operation.
The newer ones have filters for the water.

 

Park it with all of the hyd cylinder seals pointed down if you can. I don't know how water gets by when oil doesn't but it can.

Condensation is the biggest problem though. Older Kubotas, Case and Massey didn't paint the inside of any of their castings and were real bad about it. I was changing out fluid any time I worked on them at the last dealer because of it. Not much you can do about that unless you use that special red sealer paint inside everything. It helps.
My farmalls and new Holland never have this problem thankfully.

 

Well, Dan. There can be more to it than that. Initial water in the system, poor wipers on the hydraulics.
Hooking up to an old piece of equipment that has water in the lines due to it just being old.

Most john deers and a lot of other tractors use their Hydraulic fluid as the gear fluid as well, so leaving it in for a long time is poor maintenance.

One of the reasons water gets in, imo, is that its sucked in on the retraction of the cylinder. It makes it past the wiper into the area between the seals and the wiper, and the hydraulic pressure sucks it into the cylinder. if you got a bad wiper, and water on the whole rod, you will suck every bit in that comes past the wiper.

 

That's true. Never thought about it. Just rebuilt the cylinders when they were bad. Those farmers who brought their tractors to me were mostly dairy farmers and their tractors were so nasty all the time I had to spend a couple hours on the steam cleaner just to be able to tell what I had to work with.

Crap in cylinders is a big problem. I don't loan my implements out anymore. My new tractor is a common sump for hydraulics, trans, clutch and everything. The same hydraulic fluid goes in the drop boxes too. Last time I loaned my baler to the neighbor, that holds about 20 gals of fluid, I ended up with a sump full of nasty wet gear oil. He has an old JD and uses that to slow the leaks. That cost me about 500 bucks for a fluid change. It will never happen again.

 

I'm not a fan of hydraulic bailers.
Leap frog bailer? Or you talking about a round bailer?

As for cylinder rebuilds, most people don't know how to do it, or how they work.
Getting the parts for it is a big deal. I used to be able to go right to a business and grab them off the shelf for free when my mom worked there, but now the place is closed. They sold seals and orings and stuff to the Big 3 auto and other places, for punches and dies, yada yada.

If you have tore one apart, you know what i'm talking about. but genererally the wipers go bad first, which allows dirt into the seals inside, which eventually scores up the chrome which eventually is catastrophic fail.

Hell, most people don't even know that the rods are chrome coated.

Water could possibly seep down in past the wipers though. Its molecular structure isn't as wide as oil is, thats why we use oil, not water. Try running a hydraulic system with water, you'll have a fountain. haha.

I always did wonder why people parked their equipment so wierd.

I noticed a lot of newer equipment has the cylinders pointed in different directions to avoid that kinda stuff.


And as for dairy farmer equipment.
NEVER BUY IT!
they dont take care of their tractors.
Even if they do, they are still trashed. Cow maneaur is so hard on them. They rarely wash their tractors.
if they just use it to plow the field, it might be okay, but all their other stuff is usually never washed.

 

The wiper seals do good to last a couple years down here. Dry and dusty west Texas. I've already replaced the ones on my new square baler once and it's an 07 model. Most of my plowing and other equipment I cover the cylinders somehow to keep dust off the end that the rod comes out of.
My big baler was an old NH big round baler. It had I think 12 hydraulic cylinders on it and was a nightmare. I got rid of it. Now the thing I have with the most is my NH square bale stacker. It's cot a big load of hydraulic cylinders on it and I was going to pull it in to the shop in the next couple weeks to redo all the wipers on it. I have two bent rods to straighten too.

Not all hydraulic cylinders are using chromed rods. The high end ones usually do but when I have to make a new one I use hardened ground and polished rod of the right diameter instead. I've found it lasts a whole lot longer as long as you don't store it with rods out, they do rust, and the rod is harder too. Some new equipment uses the same material also. I really try hard not to buy parts for hydraulic cylinders other than new seals and I get them in bulk. I make new pistons and rods when I need them. It's a whole lot cheaper.

 

Yea. your right on the cylinders.
Good ones are chromed.
I have seen polished ones also.

As for wipers, mostly all you need to do is get some silicone grease, and just smear it on the wiper to help keep moisture on it. If dirt gets on it, then who cares. As long as the grease is packed into the wiper, it will last longer.
With that style seal, you can probably use regular grease as well.

 

The boss I had at the last tractor dealer got me into using a regular oil seal installed backwards for wipers. They are usually tougher than regular wiper seals. Installed backwards keeps nearly everything out. So far I haven't been able to get the right ones to fit most of my stuff on the equipment. The tractor has backwards seals now though.

 

Well, there are like 5 different kinds of wipers, with different strengths and different heat resistances.

I cannot remember them all.
The only type I can ever remember is VITON, but i cannot remember if that was a brand or a type.
They got some with coating on them that supposedly will give you cancer if you touch it. I probably got a lot of cancer now. haha.

 

Air gives you cancer now. And water. And dirt. And everything else.
I took a bath in some hydraulic synthetic aircraft elevator fluid once and was supposed to be dead already. Also helped strip asbestos out of the engine room I was in on two ships before they told anyone it was really bad for you. I don't even want to think about all the radiation I've been exposed to. It was nice knowing you all.

 

this john deere 1050 tractor i got has a john deere 8 back hoe attachment how hard to you guys think it would be to find new seals and wipers for the cylinders on it?

 

Easy at the dealer. If it were me though, I'd pull all the seals and get teh numbers off them and buy them from a bearing and seal place. MUCH MUCH cheaper!
