hydraulic cylinder rebuilding questions

Posted by Dave on March 31, 2002 at 18:32:27 from (205.188.200.157):

I have a JD 1010 loader with a backhoe. I have just started having problems with the loader and have some questions. With the bucket curled all the way up and the control lever in neutral the bucket slowly curls over to the dump position as if the cylinders were leaking internally. Also if I push into a pile of dirt and try to curl the bucket up it will not move and I can hear the hydralic pump straining. There are no leaks and the fluid level is ok. With no load on the bucket it will curl up fine. All other hydraulics are working fine. Is this problem normally caused by internally leaking cylinders or control valve problems? Is there any way I can narrow this down to one or the other? I would hate to pull my cylinders and try to find rebuild kits for them only to find out they are ok. This just happened out of the blue, working fine one minute and not working the next. If I have to rebuild the cylinders is it normally just an oring replacement? I have never done one before but have an idea of how they work. Thanks for any info or tips.
