Once again, I have hydraulic issues with my IH industrial 3414. I am humbly requesting advice from all of you experts out there who may have pulled a front pump on one because of FEL issues.
Tractor was doing some work dragging a blade around when I heard a buzzing/rattling mechanical-type noise coming from the engine, over the regular noise of the diesel engine. When I reduced the RPM the noise abated somewhat but didn't go away.
I grounded the front end loader bucket, and shut it off. I walked around, looking for anything amiss. No blown lines, no puddles of oil or water...no odd root stuck in the fan, nothing. Hyd reservoir was a little low, but still had enough fluid in it. I started it back up...still made the noise, but the loader lift and bucket curl cylinders were now non-responsive, no movement at all.
I looked at the front of the engine, and the pump drive shaft was still turning, the belts were still intact and turning. The noise is loudest at the front of the engine, to my ear, it seems about where the water pump is. I would have thought that if the pump crapped itself the noise would be there, forward of the radiator but it doesn't really sound that way. (The power steering and 3pt lift are fine, so the dual pump is still working, and having both lift and curl cylinders go out at once just seems like a pump gone bad to me).
My first instinct is to just pull the pump and replace it. But, knowing this machine it's probably not that simple, so I could use any advice about what else to check, and any diagnostic methods to keep me from replacing a functioning pump if it might be something else.
Thanks for your help
