Designed to work on Cummins B and C series diesel engines and for Dodge pickup 5.9L diesel engines.
Also features a load-bearing collar for friction-free use while rotating it in the housing. Just insert this engine barring tool into the flywheel housing until it engages the ring gear.
Then attach a 1/2" Dr. square drive ratchet or breaker bar, and turn it to rotate the engine, makes the job easy.
