[QUOTE="SPEOPL1443, post: 130559, member: 24057"] I recently rebuilt one of boom lift cylinders and now the boom is very slow to lift and will not lift under pressure. The machine drives great (forward, backward & turns). The bucket cylinder operates with no issues. My thought was I needed to bleed air from the rebuilt cylinder. I loosened the Allen screw near the top of the rebuilt cylinder until a small amount of fluid came out, let the machine idle for several minutes and even raised and lowered the boom several times. After tightening the Allen screw, I check the hydraulic fluid level and no change. Any other suggestions before I take it to the dealer and spend lots of money? Thanks [/QUOTE]
