PUMP GP-PISTON 2141097 - Caterpillar

In order to properly install the hydraulically actuated Pin Grabber Coupler, the host machine must be equipped with the appropriate recommended Caterpillar hydraulic control kit or an equivalent kit. Regardless of the source, any non-Caterpillar hydraulic control kit must provide the same system functions as the recommended Caterpillar hydraulic control kit in order to ensure safe operation of the coupler.
At the time of publication, the following machines have been approved by Caterpillar as host machines for the quick coupler. The machines have been rated with the standard configuration for the machines. Consult your Caterpillar dealer for additional information.
The Caterpillar Quick Coupler (Hydraulic Pin Grabber) is compatible with Caterpillar hydra-mechanical tools but may experience increased wear where there is long exposure to excessive vibration. The vibration caused by extensive use of a hydraulic hammer as well as the added weight of certain demolition tools such as shears, crushers, and pulverizers may cause premature wear and decreased service life of the coupler.Be sure to carefully inspect the coupler daily for cracks, bent components, wear, distressed welds, etc. when operating with any of the above work tools.
