I lost Hyd power, bucket slow to lift and full curl makes noise under tractor seat, its not metal noise.
Checked level yellow dip stick, it's OK.
This started after I connected a Power Beyond standard type removing the cross pipe under drivers seat.
This is for a Backhoe and the backhoe operates but also end of movements makes that noise under load.
I saw somewhere that the PB short hose you reconnect for normal use, if you don't connect it it may cause damage.
The sound reminds me of what the Hyd. pump would sound like it it was low flow.
So taking the backhoe off doesn't make any difference.
It use to work great before I know electronics but not this issue.

I hope someone know the sound I'm talking about.
If it helps call me, I'll give you my e-mail then I'll give you the cell number then.
Thanks Barry

Yes it was......M134346.
I had no idea why I lost hyd. power and that strange noise under the seat area.
Guess the sound was air. It was a very small big of oil at the botton of the center top inlet.
Anyway I guess thats the way to learn.

Those manifolds are well know for cracking with age, that same basic design was used on a lot of machines.
