I have not been able to get a guage on it yet. A new valve is being shipped and should be here in a couple of days. Dealer said sound like it has to be in valve and they covering it under warrenty, but other then that they "never heard of anything like this before."
Seems like my issue would be a common problem that would have common causes.
As I am waiting for this valve to show up, I have been trying to learn a little along the way and have been trying to dig up some info on hydraulic noises.
I have read about "hydraulic hammering" which I kinda think is what I have going on. Says hydraulic hammering caused by fluid moving through system and being suddenly slowed or stopped, thus causing a surge and clunk noise as pressure slamms into its restriction or sudden valve change.
This can be fixed with flow restrictors and such, which I don't think is what I have to do.
I think in my loader valve there is something wrong, broke, cracked, stuck, bad o ring, whichever, in the bucket function neautral valving causing all my issues. Such as a blockage that
1. Is causing flow restriction and my noise I am hearing when returning valve to neautral (fluid slamming into this blockage instead of moving freely through its open center circut) 2. Causing flow restriction and fluid/hoses to heat up.
3. Causing flow restriction and the noise I hear in the pump, like a electrial shock, this being cavitation.
4. Causing air to get into the bucket cylinders, thus not allowing the bucket to hold itself in dump position when backdragging. Bucket will dump, but as soon as I start to back up to drag, bucket cylinders would collapse or give unless I help valve in dump function for while back dragging. I think cylinders would collapse with the air in them (fluid wouldn't dump bucket, gravity did due to limited hyd fluid flow caused by blockage)
I hope you guys are understanding wat I am trying to say. I am not good at explaining things either. Any way this is my theory. What do you guys think? I hope this new valve fixes my issues.
