Abstract

A bushing assembly displacing system for displacing a bushing assembly relative to a housing opening in a structural member, the bushing assembly displacing system comprising a drive system comprising an actuator, a threaded rod, and a brace nut, a pullbar socket, and a push adapter. The pullbar socket is configured to be connected to the threaded rod and to the bushing rod. The push adapter is configured to be connected to the bushing rod and to engage the bushing sleeve of the assembly. The receiver assembly comprises a cylinder adapter and an extension tube. In a first mode, the cylinder adapter is arranged between the actuator and the structural member. In a second mode, the cylinder adapter is arranged between the actuator and the extension tube and the extension tube is arranged between the cylinder adapter and the structural member.

First claim

What is claimed is:

1. A bushing assembly displacing system for 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 bushing assembly displacing system comprising: a drive system comprising an actuator, a threaded rod, and a brace nut, a pullbar socket configured to be connected to the threaded rod and to the bushing rod; a push adapter configured to be connected to the bushing rod and to engage the bushing sleeve; a receiver assembly comprising a cylinder adapter, and an extension tube; wherein the bushing assembly displacing system is configured in a first mode in which the cylinder adapter is arranged between the actuator and the structural member, and a second mode in which the cylinder adapter is arranged between the actuator and the extension tube and the extension tube is arranged between the cylinder adapter and the structural member.

2. A bushing assembly displacing system as recited in claim 1 , in which the receiver assembly further comprises a cylinder tube cap, where:
in the first mode, the cylinder tube cap is arranged between the cylinder adapter and the structural member; and
in the second mode, the cylinder tube cap is arranged between the extension tube and the structural member.

3. A bushing assembly displacing system as recited in claim 1 , further comprising a pin arranged to connect the pullbar socket to the bushing rod.

4. A bushing assembly displacing system as recited in claim 1 , further comprising a pin arranged to connect the push adapter to the bushing rod.

5. A bushing assembly displacing system as recited in claim 1 , further comprising: a first pin arranged to connect the pullbar socket to the bushing rod; and a second pin arranged to connect the push adapter to the bushing rod.

6. A bushing assembly displacing system as recited in claim 1 , in which the receiver assembly is sized and dimensioned to receive at least a portion of the bushing assembly.

7. 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,
providing a pullbar socket configured to be connected to the threaded rod and to the bushing rod;
providing a push adapter configured to be connected to the bushing rod and to engage the bushing sleeve;
providing a receiver assembly comprising
a cylinder adapter, and
an extension tube;

a first mode, arranging the cylinder adapter between the actuator and the structural member, and
in a second mode, arranging the cylinder adapter between the actuator and the extension tube and the extension tube between the cylinder adapter and the structural member.

8. A method as recited in claim 7 , in which the step of providing the receiver assembly further comprises the step of providing a cylinder tube cap, where:
in the first mode, the cylinder tube cap is arranged between the cylinder adapter and the structural member; and
in the second mode, the cylinder tube cap is arranged between the extension tube and the structural member.

9. A method as recited in claim 7 , further comprising the step of arranging a pin to connect the pullbar socket to the bushing rod.

10. A method as recited in claim 7 , further comprising the step of arranging a pin arranged the push adapter to the bushing rod.

11. A method as recited in claim 7 , further comprising the steps of:
arranging a first pin to connect the pullbar socket to the bushing rod; and
arranging a second pin to connect the push adapter to the bushing rod.

12. A method as recited in claim 7 , further comprising the step of sizing and dimensioning the receiver assembly to receive at least a portion of the bushing assembly.

13. A method as recited in claim 7 , in which, to displace the bushing assembly into the housing opening in the structural member, the method is operated initially in the first mode and then in the second mode.

14. A bushing assembly displacing system for 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 bushing assembly displacing system comprising: a drive system comprising an actuator, a threaded rod, and a brace nut, a pullbar socket configured to be connected to the threaded rod and to the bushing rod; a push adapter configured to be connected to the bushing rod and to engage the bushing sleeve; a receiver assembly comprising a cylinder adapter, an extension tube, and a cylinder tube cap; wherein the bushing assembly displacing system is configured in a first mode in which the cylinder adapter is arranged between the actuator and the structural member and the cylinder tube cap is arranged between the cylinder adapter and the structural member, and a second mode in which the cylinder adapter is arranged between the actuator and the extension tube, the extension tube is arranged between the cylinder adapter and the structural member, and the cylinder tube cap is arranged between the extension tube and the structural member.

15. A bushing assembly displacing system as recited in claim 14 , further comprising a pin arranged to connect the pullbar socket to the bushing rod.

16. A bushing assembly displacing system as recited in claim 14 , further comprising a pin arranged to connect the push adapter to the bushing rod.

17. A bushing assembly displacing system as recited in claim 14 , further comprising: a first pin arranged to connect the pullbar socket to the bushing rod; and a second pin arranged to connect the push adapter to the bushing rod.

18. A bushing assembly displacing system as recited in claim 14 , in which the receiver assembly is sized and dimensioned to receive at least a portion of the bushing assembly.
