Product Detail

Hydraulic Motor 23B-62-11500 / 23B6211500 – Komatsu Motor Grader Parts

The circle drive motor , also known as the circle rotator hydraulic motor, provides continuous 360-degree rotary motion to the moldboard circle on a Komatsu motor grader. When the circle drive motor fails, the operator loses the ability to index the blade to the left or right side of the machine – an essential function for grading slopes, cutting ditches, and working in reverse. The grader can still move, but blade positioning becomes severely limited, and grading efficiency drops dramatically.
