## Abstract

A bushing displacing system comprising an engaging member and a brace member. The engaging member is configured to engage the brace assembly to displace the engaging member in the displacement direction and at least a portion of the bushing assembly to displace at least a portion of the bushing assembly in the displacement direction. The brace member is adapted to engage the brace assembly and the structural member. Operation of the actuator displaces at least one of the brace assembly and the engaging member in the displacement direction relative to the structural member such that the engaging member displaces at least a portion of the bushing assembly towards a desired position relative to the housing opening in the structural member.

## Claims

### Claim 1

A method of displacing a bushing assembly relative to a housing opening in a structural member, the bushing assembly comprising a bushing rod and a bushing sleeve, the method comprising the steps of:
providing a drive system comprising an actuator, a threaded rod, and a brace nut,
operatively connecting a pullbar socket to the threaded rod and the bushing rod;
arranging a receiver assembly to engage the structural member and the actuator; and
operating the actuator to displace the brace nut, the threaded rod, and the pullbar socket to remove the bushing rod from the housing assembly;
operatively connecting a push adapter to the bushing rod; and
operating the actuator to displace the brace nut, the threaded rod, and the pullbar socket to insert the bushing assembly into the housing opening.

### Claim 2

A method of displacing a bushing assembly relative to a housing opening in a structural member, the bushing assembly comprising a bushing rod and a bushing sleeve, the method comprising the steps of:
providing a drive system comprising an actuator, a threaded rod, and a brace nut,
operatively connecting a pullbar socket to the threaded rod and the bushing rod;
arranging a receiver assembly to engage the structural member and the actuator;
operating the actuator to displace the brace nut, the threaded rod, and the pullbar socket to remove the bushing rod from the housing assembly;
operatively connecting a sleeve remover to the threaded rod; and
operating the actuator to displace the brace nut, the threaded rod, the pullbar socket, and the sleeve remover to remove the bushing sleeve from the housing opening.
