Abstract: An exemplary method may comprise: ascertaining an original distance between a first tooth face and a second tooth face of a sprocket tooth, wherein the sprocket tooth comprises two tooth faces extending from a sprocket core and terminating in a top of the sprocket tooth, wherein an original distance separates the two tooth faces, placing a sprocket gauge on the sprocket tooth, wherein the sprocket gauge comprises: a bottom, and two gauge faces extending from the bottom of the sprocket gauge, wherein the bottom of the sprocket gauge is disposed upon the top of the sprocket tooth and the first gauge face is disposed adjacently on the first tooth; and comparing the original distance defined by the sprocket gauge with an actual distance between the first tooth face and the second tooth face.

Abstract: Disclosed herein are methods for utilizing cutting impact force, bearing temperature, and vibration information of a chipper machine, which comprises monitoring cutting forces generated by the knives cutting logs and monitoring the temperature of the bearings and the knives in the chipper machine. The methods may further comprise identifying a series of cutting impact forces and temperatures to indicate the condition of the bearing, and repairing, replacing, or servicing the bearing or the knives based on the value of the impact forces and temperatures measurements.
