Check the condition of the threads on rod (11) and nut (6) . If the threads are worn or damaged, use new parts for replacement.
Assemble the recoil spring assembly loosely. Position spring (10) onto the tube inside support (9) . Install rod (11) into the tube inside support (9) . Position support (12) .

Note: Two adjustable supports (1) , reaction plate (2) , and movable plate (3) are part of Tooling (A) .
Adjust the spacing between reaction plate (2) and movable plate (3) . The spacing is approximately the same length as the free length of the recoil spring assembly. The free length of the recoil spring assembly is approximately 677 mm (27 inch). Also, make sure that two adjustable supports (1) are positioned between the reaction plate and the movable plate, as shown. Level the two supports.Note: The recoil spring assembly may be installed in Tooling (A) from the end. In this case, reaction plate (2) must be removed. Then reinstall the reaction plate after the recoil spring assembly is in place on two adjustable supports (1) .
Do not remove the hoist from the recoil spring assembly until the unit is leveled, centered and locked in the specified tooling.
Fasten an appropriate lifting device to the recoil spring assembly. The combined weight of the recoil spring assembly is approximately 192 kg (423 lb). Place the recoil spring assembly in position on two adjustable supports (1) in Tooling (A) .
Adjust the two adjustable supports in order to align the centerline of the recoil spring assembly with the centerline of Tooling (A) .

The appropriate lifting device has been removed from the recoil spring assembly in order to provide a better illustration of level gauge (4) .
Operate Tooling (B) and guide the end of the recoil spring assembly through the hole in reaction plate (2) . Put a level gauge (4) on the recoil spring assembly. Make sure that the recoil spring assembly is level and centered in Tooling (A) . Remove the appropriate lifting device from the recoil spring assembly.
Several tons of force are required to compress the recoil spring during assembly.Do not compress the spring assembly until the covers on the tooling have been closed.It is possible for the recoil spring to twist under load and come out of the tooling resulting in injury or death.

Open the covers on Tooling (A) . Measure the assembled length of the recoil spring. The assembled length (X) must be 582 mm (22.9 inch).
If the assembled length is not correct, close covers (7) on Tooling (A) , and adjust the spring length with Tooling (B) . If the assembled length is correct, the assembly of the recoil spring assembly can be completed.
