Kent modified this puller and developed a procedure to remove the front crank seal race so the job could be affordable from the DIY mechanic. This costs less than half the cost of the factory tool. It is not as fast or as "slick" as the "big boy" but it gets the job done on most front crank seal races on both gas and diesel engines from the mid-1960s to the late 1980s. Watch the video below to learn more.
A good electric heat gun is needed to make this tool work in most cases.
