Used with M48 flat sided nut that is 65 mm (2.56 inch) between the two flats.
Start By:
a. Remove the front idler and the recoil spring assembly.
The spring of the recoil spring assembly is compressed under several
tons of force.
Do not attempt to compress or release the tension of the spring with the
nut on the end of the retaining rod.
Damaged threads on the retaining rod or nut can cause the assembly to
come apart with force, resulting in injury or death.
1. Prior to disassembling the recoil spring assembly, make sure that Tooling (A) is on a level
surface.
2. Prior to disassembling the recoil spring thoroughly clean the outside surface.

Note: Completely fill the seal grooves in the piston assembly with Tooling (B). The grease will
displace air when the O-ring seals and the backup rings are installed.
5. Install backup rings (7), backup rings (8), and O-ring seals (9) on piston assembly (5).
Note: O-ring seals and backup rings must be installed in the correct position in order to ensure the
correct operation of the hydraulic track adjuster. Backup rings are distinguished by the color of the
ring. Backup rings (7) are black in color. Backup rings (8) are brown in color.
Illustration 4 g02723581
Note: Completely fill in the seal groove for O-ring seal (3) and backup ring (4) in cylinder (2) with
Tooling (B). The grease will displace air when the O-ring and the backup ring are installed.
6. Install O-ring seal (4) and backup ring (3) in cylinder (2).
7. Apply Tooling (B) in the groove for lip seal (6). Use Tooling (A) to install lip seal (6). Install lip seal
(6) until the seal is 0.5 ± 0.5 mm (0.02 ± 0.02 inch) below the surface of cylinder (2). Install lip seal
(6) with the lip toward the outside of cylinder (2).
8. Check the condition of the threads on rod (1). If the threads are damaged or worn, replace rod (1)
with a new part. Put a small amount of Tooling (B) on the sliding surface of rod (1). Install rod (1) in

22. 10. Put a small amount of Tooling (B) on the sliding surface of piston assembly (5). Put a minimum of
60 cc (4 in3
) of Tooling (B) on the end of piston assembly (5). This grease will prevent air from
displacing grease in the cylinder during the installation of the piston. Make sure that the grease
covers backup rings (7) and (8) and O-ring seal (9).
11. Center piston assembly (5) in cylinder (2). Insert the piston assembly into the cylinder.
Note: It may be necessary to use a soft faced hammer to install the piston assembly into the cylinder.
12. Make sure that grease is expelled from the vent hole for the relief valve. Tighten relief valve (12) to
a torque of 34 ± 5 N·m (25 ± 4 lb ft).
13. Add approximately 5 cc (.3 in3
) of Tooling (B) through fill valve (13). Apply a force to piston
assembly (5) and open fill valve (13) in order to purge all the air from the hydraulic track adjuster.
14. Tighten fill valve (13) to a torque of 34 ± 5 N·m (25 ± 4 lb ft).
