J.D. 1010c crawler loader

My hydraulics not working properly. Jerky in operation and bouncy when holding a load and moving. Driving me nuts. Have no idea if there are any filters or relief valves or whatever in the system.

Their is a filter in the hydraulic reservoir. Google JD parts on line and do a search for 1010, Their is a parts download for your machine, 1010 crawler loader.

Thanks for the response. I have found the filter and from all appearances it would do no harm to replace it. I tried to Google the 1010c but haven't found a site that recognizes it. Apparently J.D. doesn't support it anymore. My question now would be could the filter cause the problems I'm having?

The filter would be a good start. If it has a suction filter or has a suction strainer in the tank, either would cause the pump to struggle to supply oil volume.

When the pump struggles to get enough oil, it causes high vacuum on the suction side of the pump, which can cause air to suck in around the pump seal, the filter canister, or any loose connection that may not leak externally, but allow air to enter the pump.

This starts a viscous cycle. Once air is entering the pump, the air contaminated oil is sent through the hydraulic system and back to the tank, only to be picked up by the pump again, this time with air bubbles already in the oil!

I'm assuming there is no doubt about the oil level being correct.

Also inspect the suction side plumbing of the pump. Look for loose fittings, cracked or rubbed lines, bad orings in the pump and the pump shaft seal. Just because it doesn't leak oil, doesn't mean it's not sucking air.

If there have been any modifications to the hydraulic system, that would be a good place to look. Any oil return lines that may have been added can cause problems if there is no down tube inside the tank to keep the returning oil from carrying bubbles into the oil.

I just checked. The 34 page parts diagram book is still their, pg 14 shows the filter in the tank. Just put 1010 ( leave out the "c" )in the search and it will come up in the list the program generates. Yes a plugged filter would cause the problem you describe.

Thanks guys. I have found the parts list and the breakdown. It is an immense help to be able to see what should be there. Apparently what has happened is the assembly became unscrewed from the cover and dropped. Knowing the problem is half the job. (or more) Now all I have to do is fix it. Thanks again definitely appreciate the assistance.

1010 crawler loader has two hydraulic filters and both are in the tank. A suction filter and a return filter. If the return filter gets plugged - there is a filter restriction indicator on the outside of the tank that you can easily see when running the machine. That filter is Deere # AT24274. The other filter inside the tank (suction filter) is metal and can be cleaned and reused. A new one from Deere is near $100. Still available, part # AU11215.

Those filters are almost always off and at the bottom of the tank. With 1010s and 350s. That's because the steel bushing gets lost that goes inside the return filter. Without that bushing - the long bolt cannot be tightened very much without crushing the filter and it quickly falls off.

Where pray tell did you get the idea that JD does not support the 1010 at all ?
The parts book is online on the JD web site.

Hello
I have a 720 loader (on 2010) that uses the same tank and filters as the 1010 crawler. All the parts for the return filter are gone (not laying in the bottom). I can get the filter and make and end cap. They is a filter slid on the suction tube (reusable) But the top of the filter is open, is this correct? I have looked at the drawings and the 2 filter appear to be one assembly, but that doesn't seem correct because suction is at the bottom of tank and return is part of the cap at the top. Any help is appreciated.
Thanks
