RETAINER SYSTEMS

A wear part and retainer system in combination, for earthmoving and mining equipment, the wear part having a first passage extending therethrough in one direction and a second passage extending in a direction lateral to and intersecting the first passage. The first and second passages each have an outer end and an inner end. A latching member is mounted in the first passage for movement between a non-latching position and a latching position in which it locks the wear part to a mother part. The latching member has a recess therein and a biasing element mounted in the recess. A locking pin is mounted in the second passage for selective movement along the passage between a retracted position in which the latching member is free to move into and out of the recess and an extended position in which it locks the latch in the latching position.
