Hydra-Test USA has unveiled a new testing solution for the double dry clutch 0AM (DQ-200) valve body. The benchtop model is an “all in one” solution that tests the complete unit. For customers with an existing Hydra-Test machine with the HTC controller, there is a direct plug-in version. The 0AM (DQ200) testing tool verifies the
