Seat removal and installation for the overhead valve engine presents challenges. The bottom ledges of the seats are not exposed, creating a need to machine a center groove in the inside diameter of the seats.

The E-Z Bore puller assembly comes with a hex mandrel and interchangeable jaws for intake and exhaust seats. Simply position the mandrel assembly with the correct jaws and expand into machined groove in seat. After installing mandrel assembly, place puller block across gasket surface of head and tighten puller to draw seat out of cylinder head.

Storage case included!

End mill and saw/grooving tool are available separately for Briggs & Stratton 6.5HP Animal engines only.
