6mm Closer Shim Assembly Tool
If your Duc has 6mm valves then this is a must for your tool box. The 6mm closer shim assembly tool facilitates the proper assembly of the closer shim on its taper using the specified torque of 8 Nm (5.9ft/lb). It has been redesigned to allow its use without the need to remove the opening rocker arm. It has a window machined into it that allows the opening rocker arm to protrude through it while still in place.
