In the heavy machinery industry, reliability is determined by the quality of every single component. When your 160H Motor Grader requires an engine overhaul or routine maintenance, selecting the right coupling is critical for power transmission stability.
We provide the 125-2989 (1252989) Coupling Assy, specifically engineered for the 160H series equipment. This aluminum housing coupling ensures superior heat dissipation and vibration dampening, protecting your engine and hydraulic systems from premature wear.

This is often a sign of a worn 125-2989 coupling. If the aluminum teeth or the internal insert is damaged, it creates metal-to-metal contact. Solution: Immediate inspection and replacement with a new 1252989 coupling to avoid pump shaft damage.
In 160H graders, this indicates the coupling assy is disintegrating. Solution: During a 160H engine overhaul, the coupling should always be replaced as a preventive measure to ensure the longevity of the hydraulic system.
Answer: Our product utilizes an OEM-standard tri-metal structure. It is trusted by repair shops and equipment fleets globally for its ability to handle high torque loads without fatigue.
