COUPLING AS- 1196730 - Caterpillar

Sudden release of spring force can cause injury.To prevent the possibility of injury, follow the procedure to relieve the spring pressure.
Check the condition of the threads on retaining rod (13) and nut (8). If the threads are damaged, use new parts for replacement.

Tooling (A)
( 2) Reaction plate
(3) Movable plate
Determine the position for the recoil spring assembly in Tooling (A). Place adjustable support (1) of Tooling (A) in this position. Level the adjustable support.

Attach a suitable lifting device to the recoil spring assembly. Position the recoil spring assembly in Tooling (A). The weight of the recoil spring assembly is approximately 24 kg (53 lb). Use the following procedure to position the recoil spring assembly in Tooling (A).
Level the recoil spring assembly by repositioning the adjustable support (1).
Position the recoil spring assembly so that nut (8) and the washer can be installed through the access hole in reaction plate (2).
Install two pins (7) on the back side of reaction plate (2), as shown.
Operate Tooling (B) enough to hold the recoil spring assembly in position between reaction plate (2) and movable plate (3).
Be sure that the recoil spring assembly is leveled and centered in Tooling (A).
Remove the hoist from the recoil spring assembly.

Close covers (9) on Tooling (A). Use the following procedure to adjust the preloaded length of the recoil spring assembly.
Operate Tooling (B) and slowly compress the recoil spring assembly. Use the access hole in reaction plate (2) and guide the end of the retaining rod into position in support (10).
Open the covers on Tooling (A). Determine Dimension (X) by measuring the length of recoil spring (11) and support (12). Dimension (X) must be 339.0 1.0 mm (13.35 0.04 inch).
If the compressed length of the recoil spring is not correct, close covers (9) on Tooling (A). Use Tooling (B) to adjust Dimension (X) to the correct length.
If the compressed length of the recoil spring is correct, assembly of the recoil spring assembly can be completed.
Install the washer and nut (8). Be sure that all of the threads in nut (8) are engaged with threads on the retaining rod.
Operate Tooling (B) and release the pressure on the recoil spring assembly. Open the covers on Tooling (A).
