Note: Cleanliness is an important factor. Before assembly, clean all parts in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. All assembly procedures must be performed on a clean work surface and in a clean hydraulic area. Keep cleaned parts covered and protected at all times.
Note: Check the O-ring seals and seals for wear or for damage. Replace the components, if necessary.

Personal injury or death can result from recoil spring force. Recoil spring force, if not relieved, can result in personal injury or death. Relieve spring force before removing threaded retainer, performing repairs on recoil spring housing, or removing recoil spring. |
- Install tube (11) onto adjuster assembly (10).
- Attach a suitable lifting device to recoil spring (12). Install recoil spring (12) onto adjuster assembly (10).

Illustration 6 g00832545 Note: Two adjustable supports (1), reaction plate (2), and movable plate (3) are part of Tooling (A).
- Position two supports (1) of Tooling (A) in order to support the recoil spring assembly. Make sure that the two supports are level.
- 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.

Illustration 8 g00832845 Note: Do not remove the lifting device from recoil spring assembly (4) until the unit is centered and locked in Tooling (A).
Note: Recoil spring assembly (4) may be installed in Tooling (A) from the end. In this case, the reaction plate must be removed. Then reinstall the reaction plate after the recoil spring assembly is in place on the two adjustable supports in Tooling (A).
Note: The lifting device is removed from recoil spring assembly (4) for photographic purposes.
- Attach an appropriate lifting device to recoil spring assembly (4). The weight of the recoil spring assembly is approximately
53 kg (117 lb) . Carefully lift the loosely assembled recoil spring assembly and position the recoil spring assembly on two adjustable supports (1) in Tooling (A). - Adjust the two adjustable supports until the centerline of recoil spring assembly (4) and the centerline of Tooling (A) are aligned.
- Reposition the recoil spring assembly until the rod of the adjuster assembly is centered in the hole in reaction plate (2). Refer to Illustration 8.

Illustration 10 g00832618 - After the recoil spring assembly is centered, install pins (5) on the back side of the reaction plate, as shown.
- Operate Tooling (B) enough to hold the recoil spring assembly in position between the reaction plate and the movable plate. Make sure that the recoil spring assembly is centered. Make sure that the rod of adjuster assembly (10) and the hole in washer (13) are centered with the hole in reaction plate (2).

Illustration 12 g01353022 - Close covers (6) on Tooling (A). Use Tooling (B) to compress the recoil spring assembly slightly.
- Open covers (6) on Tooling (A). Measure Dimension (X). The compressed length of Dimension (X) must be
404.6 mm (15.9 inch) . If the compressed length of Dimension (X) is not correct, close covers (6) on Tooling (A) and adjust the length with Tooling (B). Adjust the length of Dimension (X) until the compressed length of Dimension (X) is correct.Show/hide table
Illustration 13 g01352888 - Install special nut (7). Slowly release the pressure on Tooling (B) until special nut (7) is seated against plate (10).
- Install strap (9) and install bolts (8).
