CP-563 (1YJ, 5AJ) Vibratory Compactors
Reference: Service Magazine; December 6, 1993; Page 11; "Improved Hydraulic Hose Retention Minimizes Rubbing and Chafing" for CS-563, CP-563 Vibratory Compactors.
Description of Change: The hydraulic lines from the blade control valve to the blade cylinder has been updated to incorporate the use of steel tubes.
Adaptable To: The improved leveling blade lines are effective with CP-563 (1YJ385, 5AJ125 Vibratory Compactors). To adapt earlier machines, use the following procedure.
NOTE: Earlier machines (1YJ1-384, 5AJ1-106) must be modified as described in the Reference Article before the procedure in this article can be performed.
Procedure To Install Steel Tubes In Blade Circuit
Illustration 1. Existing Blade System Lines (A) Hoses. (B) Fittings. (C) Blade cylinder. (D) Hose retaining clips. (E) Blade control valve.
1. Remove and discard two blade cylinder hoses (A), retaining clips (D) and two fittings (B). Plug the open hydraulic ports on blade control valve (E) and cylinder (C).
2. Weld five plates (1), and four brackets (2), and four weld nuts (3) as shown in Illustration 2.

Illustration 3. Location Of Tubes (5)
3. Use Illustration 3 to install two tubes (5) on the left side of the drum yoke when viewed from the operators station. Secure tubes (5) in place with ten half clamps (6), five plates (7), and five bolts (8).
4. Install cover (4) on top of brackets (2) with four bolts (25) and four washers (26).

5. Use Illustration 4 to install two hoses (9), four o-ring seals (14) and six half clamps (10).
Clamp assembly (EE) requires two plates (11), one bolt (28), and one locknut (13). Position the clamp as shown in Illustration 4.
6. Secure the final two clamp assemblies to the front of the drum yoke. Use one plate (11) and one bolt (12) for each clamp. Thread the bolts into the existing weld-nuts.

7. Use Illustration 5 to install the O-ring seal (16), adapter (17), O-ring seal (18), elbow (20), and O-ring seal (19).
8. Use illustration 5 to install the O-ring seal (18), elbow (15), and O-ring seal (16).

9. Use Illustration 6 to install hose (21) between elbow (20) and tube (5) that is closest to the drum. Install hose (22) between elbow (15) and tube (5) that is farthest from the drum. Install one O-ring seal (14) at each end of both hoses.
Illustration 7. Modification Of Clamp Bars (X) Bar. (Y) 32 mm (1.3 in) reference. (Z) 16 ± 1 mm (.6 ± .04 in). (AA) 4 mm (.2 in) fillet weld. (BB) 144 mm (5.7 in) reference. (CC) 126 mm (5 in) reference. (DD) 60 ± 1 mm (2.4 ± .03 in). (27) Plate.
10. Weld plates (27) to bars (X), as shown in Illustration 7.
NOTE: The machine must have the propel and vibratory hose clamp modifications described in the Reference Article.
11. Install the modified bars (X) on the propel and vibratory hose clamp assemblies.
12. Secure hose (21) and hose (22) with four double clamps (23), two plates (7) and two bolts (24) as shown in Illustration 6.
