I am fairly new to skid steers, bought a Bobcat 743 about 4 months ago. I developed a leak out the back of the spool valve. I removed the spool valve and replace the seals. Since reinstalling the spool valve I have ran the machine around and believe all the air is out of the system. My problem is that it will not lift the arms up or tilt the bucket more than an inch or two before it stops any thoughts on what might be wrong? I retraced all the lines and believe they are all hooked up right.
