    Hi all. I have a 1999 331 bobcat excavator that has hydraulic issues. Here is what i have so far.
    The stick out and in is very slow, bucket open and close is very slow, left final drive is slow.
    When i stick out and bucket open they both move faster. The same when i close bucket and stick in, they both are faster. All else seems at normal speed. I have completed pressure tests at the main pump they are at pump 1, 2300psi 2, 2600psi and 3 2600 psi under load. The other odd thing i found was that the stick only measured 1000psi when operated
    Im scratching my head here and any help would be great.
