Abstract

A quick connect/disconnect system for an arm of an excavator or other machine includes a boom comprising a distal end defining a first yoke structure including first and second yoke members, and each of the yoke members includes an open pin-receiving recess. An arm includes first and second pin-ends projecting outwardly therefrom. The first pin-end is seated in the recess of the first yoke member and said second pin-end is seated in the recess of the second yoke member. First and second arm keepers are located respectively adjacent the first and second recesses and selectively capture the first and second pin-ends. The system optionally includes a second yoke with first and second yoke members that respectively include first and second open pin-receiving recesses. An arm cylinder includes first and second cylinder pin-ends projecting outwardly therefrom. The first cylinder pin-end is seated in the first recess of the second yoke and the second pin-end is seated in the second recess of the second yoke. First and second cylinder keepers selectively capture the first and second cylinder pin-ends. The system also optionally includes a cylinder support assembly for supporting the arm cylinder relative to the boom when the arm is disconnected from the boom.
