ABSTRACT:
A well unit dynamometer installation means and method. A reciprocal well unit is operated with a spacer mounted on the polish rod above the carrier bar. To install a dynamometer the unit is stopped, the loading removed from the carrier bar, the spacer removed and the dynamometer attached to the polish rod above the carrier bar. The spacer comprises nested sleeves, each having a slot. The outer sleeve rotates with respect to the inner sleeve, allowing the slots to be aligned so as to be slipped over the polish rod. End plates connected to the inner sleeve allow operating loads to be transmitted through the spacer during operation of the well unit.
