Last summer my Ford/New Holland 555E Loader Backhoe hydraulic overheating temperature idiot light turned on. It was hot outside because this is East Texas in summer, but it had never overheated before. I cleaned out the radiators. There are three of them, and one is just for the hydraulics. I also replaced all three filters and all of the fluid. There was quite a bit of sludge in the bottom of the tank, so I wiped it clean with paper towels. The big filter inside the tank seemed to be clogged up with sludge too, so I thought that I had found the problem.
For a couple months during the Fall, cooler temperatures outside, it ran great without any issues. But now the idiot light is turning on again. Fluid levels are good. I'm thinking that there was sludge in the lines that I didn't get cleaned out the first time and it's plugging up my filters again. I have 3 new filters and hydraulic oil.
I'm about to drain it and change the filters when I noticed that the cap isn't venting. As I unscrew the cap on the hydraulic tank, I hear air sucking into the tank. The more I turn it, the louder the sucking air sound gets. When I take the cap off, there is a popping noise from all of the air sucking into the tank.
Can a cap that is supposed to vent, and not venting, be the cause of the hydraulics over heating?
I'm going to buy a new cap and see if that helps, but was hoping for some confirmation that it might be part, or all of the issue.
Thanks
