Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Check the condition of the threads on retaining rod (12) and nut (6). If the threads are worn or damaged, use new parts for replacement.
Check the inside of support assembly (8). Make sure that the support assembly is clean and free of dirt.
Assemble the recoil spring assembly loosely.
Install spring (9) in support assembly (8). Install retaining rod (12) and support (10).

Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Fasten a suitable lifting device to the recoil spring assembly. The weight of the recoil spring assembly is approximately 227 kg (500 lb).
Put the recoil spring assembly in position on adjustable supports (1) in Tooling (A).
Adjust the adjustable supports in order to align the centerline of the recoil spring assembly with the centerline of Tooling (A).
Illustration 5 g00498760
Illustration 6 g00498781Note: The suitable lifting device has been removed from the recoil spring assembly in order to provide a better illustration of level gauge (4).
Put a level gauge (4) on the recoil spring assembly.
Reposition the recoil spring assembly until the recoil spring assembly is level. Reposition the recoil spring assembly until the retaining rod and nut (6) are centered in the hole in reaction plate (2).
The recoil spring assembly is leveled by moving adjustable supports (1) higher or lower.
After the recoil spring assembly is leveled and centered, install pins (5) on the back side of reaction plate (2).

Install Tooling (C) on Tooling (B).
Operate Tooling (B) in order to hold the recoil spring assembly in position between reaction plate (2) and movable plate (3). Refer to Illustration 6 and Illustration 2.
Make sure that the recoil spring assembly is level and centered in Tooling (A).

Illustration 9 g01891973
Make sure that a vertical centerline is at a right angle to support (10).
Install the support so that the welds are positioned properly in order to obtain Dimension (Y). Dimension (Y) is 30 20 mm (1.2 0.79 inch).
Remove the suitable lifting device. Close the covers of Tooling (A).
Compress the recoil spring assembly with Tooling (B).
Open the covers on Tooling (A), and measure the assembled length of the recoil spring assembly.
Measure the distance from the end of the support assembly to the mark on support (10).
Dimension (X) is the assembled length of the recoil spring assembly. The assembled length must be 870 mm (34 inch).
If the assembled length is not correct, close the covers
