This is the most efficient gimbal bearing removal/puller tool I have ever owned ! I was using a slide hammer with the jaws that grip onto the gimbal bearing and then you slide the hammer and try to bang out the bearing half the time the jaws would slip off the bearing and You would have to go at it for an hour before the gimbal bearing comes out or the jaws on the slide hammer would break.... this tool was a one and done removal I will never go back to the slide hammer way! This kit also comes with a nice heavy duty alignment tool that lets you know your gimbal bearing is aligned with the coupler on the fly wheel, And a gimbal bearing installment tool that slide right on to the alignment tool when you are ready to put the new gimbal bearing in and a gimbal bearing installment tool that slides right onto the alignment tool when you are ready to put the new gimbal bearing in five stars all day!
