632 bobcat

[Brian Wilhite]

I have a 632 and it runs great, it tipped over on it's side and lost 3 gallon's of Hyd fluid. I filled it up and replaced a line for the bucket. It is squealing and loss of power when using the Hydrolic's and want's to die. I was told that there is air in the lines but I have done the hole working the system up and down thing like bobcat said to do. It is getting worse, any idea's?

Those for the most part have no problems working air out of them and I have never had to "bleed" any air out of them. I wonder if the squealing you are hearing is pump damage from cavitating. The only thing I can think of for loss of power and wanting to kill the engine is excessive load like the aux hydraulic are sticking on. Ohter wise I would look to the engine itself if it is lacking power.

Check if there is an aux. hyd valve. I had one that controlled the aux. by pushing one of the drive levers sideways. The customers hired man would lean on the lever getting into the machine and lock the aux. in the detent position. Hyds. were in relief all the time and the machine had no power. Just had to bump the lever back to neutral and everything was fine.
