I am having a hydraulic issue. At first it was making a lot of noise. Checked fluid and its level is good. It would raise and lower arm, bucket, and move forward and reverse but not left or right. Pulled the cabin open and saw that the line on top of hydraulic pump was leaking at the fitting. I tighten the fitting and stopped the leak. Reading thru other post I saw that the noise and problem could be caused by air in the system and I should cycle all the the hydraulics to work the air out. While cycling all the hydraulics it completely stopped working. I currently have no hydraulics. The serial number is over 15001 so there is no port block filter to change. Are there any other filters that could be clogged besides the large hydraulic filter? Where should I start looking for the issue? Thank you for your help
