ABSTRACT:
A spring assembly and a method of assembly therefor are provided wherein one or more longitudinal coil springs are retained between two end caps. Each end cap receives a hollow pin, each pin extending axially inwardly therefrom and abutting the other pin. The pins include axially aligned threaded throughbores which receive a threaded stud whereby the pins are maintained in abutting relation. The spring assembly is assembled by means of assembly tools which serve to rotate the pins to allow the stud to be received therein and to space the stud within the pins.
