A hub puller kit for power ends of frac pumps, the hub puller kit comprising:
- an adapter flange comprising a first surface, a second surface, one or more sets of fastener openings extending from the first surface to the second surface, and a central opening, the one or more sets of fastener openings disposed radially outside of the central opening;
- and
- a hydraulic actuator coupled to the adapter flange, the hydraulic actuator comprising a hydraulic cylinder and a hydraulic plunger disposed at least partially within the hydraulic cylinder.
A method of removing a hub from a pinion shaft of a power end using a hub puller kit, the method comprising:
- positioning an adapter flange of the hub puller kit adjacent a first surface of the hub;
- fastening the adapter flange to the hub;
- pressurizing a hydraulic actuator coupled to the adapter flange to apply a first force to the hub in a first direction and a second force to the pinion shaft in a second direction, the second direction being opposite of the first direction;
- and
- moving the hub away from the pinion shaft.
