Abstract
A crimping head includes a clevis having a first arm and second arm defining a gap therebetween in which a workpiece is positioned and a nest. The crimping head further includes a first sleeve received within a first bore in the first arm and a second sleeve received within a second bore in the second arm. The first pin is received in the first sleeve for relative rotation therewith and the second pin is selectively received within the second sleeve. The hardness of the first and second sleeves is greater than the hardness of the clevis.

A crimping head coupled to a hydraulic power unit, the crimping head comprising:
- a clevis having a first arm and a second arm defining a gap therebetween in which a workpiece to be crimped is positioned,
- a nest having a first end pivotably coupled to the first arm with a first pin and an opposite, second end selectively coupled to the second arm with a second pin to rigidly affix the nest to the clevis,
- a first sleeve received within a first bore in the first arm, the first pin being received within the first sleeve for relative rotation therewith, and
- a second sleeve received within a second bore in the second arm, the second pin being selectively received within the second sleeve,
- wherein a hardness of the first and second sleeves is greater than a hardness of the clevis.
A hydraulic power tool comprising:
- a hydraulic power unit;
- and
- a crimping head coupled to the hydraulic power unit, the crimping head including
- a clevis having a first arm and a second arm defining a gap therebetween in which a workpiece to be crimped is positioned,
- a nest having a first end pivotably coupled to the first arm with a first pin and an opposite, second end selectively coupled to the second arm with a second pin to rigidly affix the nest to the clevis,
- a first sleeve received within a first bore in the first arm, the first pin being received within the first sleeve for relative rotation therewith, and
- a second sleeve received within a second bore in the second arm, the second pin being selectively received within the second sleeve,
- wherein a hardness of the first and second sleeves is greater than a hardness of the clevis.

- a nest having a first end pivotably coupled to the first arm with a first pin and an opposite, second end selectively coupled to the second arm with a second pin to rigidly affix the nest to the clevis,
- a first sleeve received within a first bore in the first arm,
- a second sleeve received within a second bore in the second arm,
- a third sleeve received within the first bore opposite the first sleeve, and
- a fourth sleeve received within the second bore opposite the second sleeve,
- wherein the first pin is received within both the first sleeve and the third sleeve for relative rotation therewith,
- wherein the second pin is slidably received within both the second sleeve and the fourth sleeve, and
- wherein a hardness of the first, second, third, and fourth sleeves is greater than a hardness of the clevis.
