Farmall 460 hydraulics heat up and dont work

Posted by matt1983 on July 14, 2011 at 18:25:17 from (71.234.106.161):

Well Ive been up and down the hydraulic system in my Farmall 460 but still havnt found a solution to hydraulic system heating up and not working after a while. I have cleaned and checked all the valves and screens and anything else I could find and I cant find anything wrong. But once the tractor has been used for about an hour the hydrauics get hot and begin to whine louder and louder and it sounds like its coming from the pump. The rear fasthitch begings to raise and drop and then it hits a point where it stays pressurized constantly and strains the engine to keep the fast hitch up. Im fairly certain at this point that the pump is bad. I think whats happening is the pump is bypassing around the worn gears and it works until it heats up the oil so much that the thinned oil cant be pushed by the worn gears (or worn housing around the gears)... Does that sound logical? If so what does everyone recommend for a pump. I know that there are 12GPM and 17GPM pumps but I would like to go bigger if possible. Any suggestions? Thanks!
