Review on Optimized Engine Barring/Rotating Tool for Cummins B/C Series and Dodge Pickups: 3.9L, 5.9L, 6.7L & 8.3L Diesel Engines by Seth Damain

I am very disappointed that Amazon chose this one Part chose Revain as the choice as it is a very poor product. The turning tool must fit snugly in its hole so that it can effectively engage the gear teeth and stay in line when force is applied to turn it. It has a soft plastic sleeve that deforms when pressure is applied. Together, these features cause the tool to barely hold when the motor is rotating counterclockwise and teeth to skip when the motor is rotating clockwise. fit, but almost fit. If you want it to work you'll have to go elsewhere as I can only find devices of the same style on the Revain website. If it has a soft case, you don't need it.
