Component Code(s) 5051SUBJECT: PLUG LOOSENING AND OIL LEAKING FROM THE MAIN HYDRAULIC
CONTROL VALVE
PROBLEM:
Reports indicate that the plugs in the main hydraulic control valve may become loose. The loose plugs can allow oil to leak from the valve.
SOLUTION:
If the plugs in the main hydraulic control valve become loose, use the procedure that follows in order to prevent oil leaks.
Illustration 1. Typical Control Valve
(A) 231-6879 Plug
(B) 3D-2824 O-Ring Seal
(C) 231-6878 Plug
(D) 7M-8485 O-Ring Seal
(E) 201-9261 Plug
(F) 4K-1388 O-Ring Seal
Remove and replace plug (A) and seal (B) if the plug becomes loose or leaks oil. Apply lubricant on the threads of a new plug (A). Tighten plug (A) to an increased torque of 200 + 20 - 0 N?m (150 + 15 - 0 lb ft).
Remove and replace plug (C) and seal (D) if the plug becomes loose or leaks oil. Apply lubricant on the threads of a new plug (C). Tighten plug (C) to an increased torque of 305 + 20 - 0 N?m (225 + 15 - 0 lb ft).
Remove and replace plug (E) and seal (F) if the plug becomes loose or leaks oil. Apply lubricant on the threads of a new plug (E). Tighten plug (E) to an increased torque of 240 + 20 - 0 N?m (175 + 15 - 0 lb ft).
The effectivity of the increased torque specification for the plugs in the main hydraulic control valve is listed in Table 1.
