1. A pivot pin, comprising:
- a) a hollow tubular sleeve having open ends, said sleeve has a uniform outside surface diameter from a first open end to a second open end, and said sleeve has a tapered inside surface such that said inside surface has a larger diameter at said first open end and a smaller diameter at said second open end;
b) said sleeve having a longitudinal axis;
c) a removable load cell, positionable inside said hollow tubular sleeve, and extending substantially the length of said sleeve and having a longitudinal axis; and
,d) strain gauge means associated with said cell for measuring axial deflection of said pin.

Abstract
A pivot pin including a hollow tubular sleeve having open ends for encircling a removable load cell having strain gauges attached thereto for measuring loads on a pivot joint. When loads are placed on a pivot joint the load cell will deflect and its deflections are detected by a strain gauge which measures the axial deflection of the load cell.
