Description of Change: New control valve groups, for the snow wing tilt and lift attachments, have replaced the former control valve groups. The valve body, for the new control valve groups, is made of stronger material to resist cracking at high pressure.
Longer bolts, with shorter thread length, replace the former bolts with long thread length to secure and prevent misalignment of the valve sections.
Adaptable To: The new 137-8104 Control Valve Group is a direct replacement for former 107-0552 Control Valve Group.
The new 137-8106 Control Valve Group is a direct replacement for former 107-0549 Control Valve Group.
Both new control valve groups are effective with 14H (7WJ368), 120H (4MK210), 135H (3YK164), 140H (2ZK1406), 143H (1AL248), 160H (9EJ352), and 163H (5AK103) Motor Graders. The new control valve groups are adaptable to earlier machines.
All other motor graders are adaptable to first production.
Typical Control Valve Group
(1) New 137-8106 Control Valve Group (snow wing lift). (2) New 137-8104 Control Valve Group (snow wing tilt). (3) Mounting bolt. (4) Mounting bolt.
