Wear assembly and removal system

Abstract

A wear member may include a mounting portion with a cavity for receiving a base for mounting the wear member to the earth working equipment, an external surface, a recess in the cavity, and a hole extending from the external surface to the recess. An insert is at least partially situated in both the recess and the hole for movement relative to the wear member to facilitate removal of the wear member from the base. Optionally, the hole may receive a lock for securing the wear member to the base. A removal tool may be installed into the hole to engage the insert to forceable engage against the base causing forward movement or removal of the wear member.

1 . A wear member for earth working equipment comprising:
 a wearable body having a working front end, a rear end with a cavity for mounting a base therein, wherein the cavity includes an opening at the rear end wherein the base is received therethrough and an opposite front surface, and a recess in the front surface; and   an insert having a front end and a rear end, wherein the insert is movably positioned in the recess in the front surface of the cavity to facilitate removal of the wear member from the base.   
     
     
         2 . The wear member of  claim 1 , wherein the wearable body includes a hole extending from an external surface to the recess. 
     
     
         3 . The wear member of  claim 2 , wherein the insert is at least partially situated in both the recess and the hole. 
     
     
         4 . The wear member of  claim 2 , wherein the hole receives a lock that secures the wear member to the base. 
     
     
         5 . The wear member of  claim 1 , wherein the recess forwardly converges and the insert includes a body having side surfaces that converge towards a front end of the insert. 
     
     
         6 . The wear member of  claim 1 , wherein the rear end of the insert includes a head that extends laterally outward from the body and acts as a stop for the insert in the recess. 
     
     
         7 . The wear member of  claim 1 , wherein the front end of the insert includes a partial threaded surface. 
     
     
         8 . A wear member for earth working equipment comprising:
 a wearable body having a working front end, a rear end with a cavity for mounting a base therein, wherein the cavity includes an open rear end through which the base is received and an opposite front surface;   a hole that opens in an external surface; and   a recess extending from the front surface of the cavity and communicating with the hole.   
     
     
         9 . The wear member of  claim 8  including a lock in the hole and a movable insert in the recess. 
     
     
         10 . A removal assembly for a wear member of an earth working equipment comprising:
 a wear member having:   a wearable body having a working front end and a rear end with a cavity for mounting a base therein, wherein the cavity includes an open rear end through which the base is received and an opposite front surface;
 a hole that opens in an external surface; and 
   a recess extending from the front surface of the cavity and communicating with the hole;   an insert within the recess and in the hole; and   a removal tool receivable in the hole to engage the insert to apply a rearward force against the insert to facilitate removal of the wear member from the base.   
     
     
         11 . The removal assembly of  claim 10 , wherein the insert has a front end formed with a thread formation and the removal tool is a threaded wedge that engages the threads on the insert. 
     
     
         12 . A method of removing a wear member from a base comprising:
 mounting a wear member on a base of an excavating equipment, wherein the wear member has an exterior surface, a cavity defined by an interior surface to receive the base, a recess extending forward from a front of the interior surface, a hole extending from the exterior surface to the recess, and an insert in the recess such that a portion of the insert is partially situated into the hole; and   inserting a removal tool through the hole to engage the insert and force the insert rearward against the base to move the wear member forward relative to the base.   
     
     
         13 . The method of  claim 10 , wherein a lock securing the wear member to the base is removed from the hole prior to inserting the removal tool through the hole.
