Abstract
A seat puller removes a valve seat or bushing from a structure such as a fluid pump. The seat puller may be formed of a shaft having a threaded adjusting nut fastening region, a central shaft region, a land region, a cone shaft region and an end stopper region. The seat puller includes a slide lock jaw held onto the shaft at the land region by a spring. The spring permits the slide lock jaw to open slightly and thereby permits the slide lock jaw to slide down the shaft to the cone shaft region. This causes the slide lock jaw to open and engage the internal and bottom surfaces of a seat with its outer circumference, thereby permitting the seat puller to remove the seat from the structure in which it is seated.
