Patent ·
OSTI ID:6505277

A method and apparatus are provided for replacing the bearing between the sampson post and the walking beam of an oil well pump. The walking beam and the pitman arms are securely fastened together to prevent relative movement therebetween. The head portion is adjustably restrained against the force of the counter-weight. The walking beam is allowed to pivot on the connection between the walking beam and the pitman arms so that the walking beam moves away from the sampson post so that the bearing may be replaced.
