The new Adapt-A-Case multi-functional tool (p/n T-135PRBRAC) tests the pressure of the 6L80/90 1-2-3-4/3-5 reverse drum to ensure there are no cracks or leaks. Simply place the tool in the drum and use an air gun in each hole to check for leaks. It also installs the bearing to the proper depth by placing the bearing on the tool and setting it on the tapping into place. For more information, visit www.adaptacase.com.
