Restoration of worn hydraulic suspension cylinder

A client contacted Entro about a possible evaluation and rebuild of a suspension cylinder for their rig. Entro performed an external inspection and proceeded to disassemble and do an internal inspection on the cylinder. Entro repaired the cylinder rod, installed new seals, wear rings and a valve block. The refurbished parts were reassembled, painted, and function tested. The cylinder was then put back in service in the North Slope of Alaska.
