Material made for a week the block broke and the ear trying to flip the block to relieve the pressure in the hydraulic block not only broke the tool ear but also twisted and broke broke the ear of the upper part of the hydraulic block, now I have the tool is broken and I have to buy another tensioner. The tool must have some sort of stop to prevent it from rotating away from its base to prevent the hydraulic tensioner from braking. To order a complete block and other tooling from your company I have another head to work on. See my purchased order
