Kent's Custom Gas Engine Front Crank Seal Race Removal Tool

Store > Engine Products
For most 4 cylinder, 6 cylinder and V8 engines from 1963 to 1985. Made to remove the race on the end of the crankshaft when replacing the front crank seal.

PLEASE NOTE: This puller is custom-modified and is made to order. It has to be narrower than the diesel version. PLEASE allow three to four days before it can be shipped to you. Kent modified this puller and developed a procedure to remove the front crank seal race so the job could be affordable for 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 GAS engines from the mid-1960s to the mid-1980s. Watch the video below to learn more.
