Required Tools
Tool Part Number Part Description Qty
A 1P-0520 Driver Group 1
B 5P-0960 Molybdenum Grease Note: Make sure that all of the parts of the hydraulic track adjuster are clean and free of dirt and debris prior to assembly.
Make sure that all of the passages in the piston assembly are filled with Tooling (B). Make sure that air is not trapped in the passages in the piston assembly.
Illustration 5 g00526455
Install relief valve (12) in the body of the piston assembly. Do not tighten the relief valve.
Install fill valve (13) in the body of the piston assembly. Tighten the fill valve snugly. Do not torque the fill valve.
Illustration 6 g00526454
Install plate (10). Install bolts (11) which secure plate (10).
Illustration 7 g00526453Note: 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.
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 8 g02723581Note: 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.
Install O-ring seal (4) and backup ring (3) in cylinder (2).
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).
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 cylinder (2).
Fill the cavity of cylinder (2) with Tooling (B).
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).
Center piston assembly (5) in cylinder (2). Insert the piston
