Just had the double cylinder in the boom rebuilt, installed everything and hoses but cylinders will not move. Do I need to bleed the cylinder?
I was thinking something about the same.Usually you just have to cycle them few times and any air will work its way out. I did one time have the dual boom cylinders rebuilt on a grove tms300 and when I reinstalled them one of the cylinders was moving really slow and fighting the other. I had to adjust the pilot check valve on one of the cylinders to get them back to opening at the same hydraulic pressure. The hydraulic shop claimed they didn't do anything to the check valves and maybe they didnt but something about the rebuild changed the pressure required to open the valve.
