Precision 11705007 steel separator plate (counterplate) by FEROSTEM. It is a component of the wet brake system, working together with friction discs. Dedicated to drive axles of Caterpillar (CAT) M300 series wheeled excavators. The disc features dense external toothing (67 teeth) and a thickness of 3 mm.
FEROSTEM parts guarantee OEM quality. Steel plates undergo precision machining to ensure perfect flatness and resistance to thermal deformation, which is crucial for braking efficiency in heavy machinery.

The above list is for reference. Before purchasing, please verify dimensions (191 mm x 67 teeth) and axle part number.
The steel plate works alternately with friction discs. When repairing brakes, it is recommended to replace the complete set (steel + friction) and fill the axle with fresh transmission oil with wet brake additives.
Installing warped steel plates, even if they look good, will cause brake dragging. This leads to rapid overheating of the axle oil and burning of new friction discs.
Plate 11705007 is a stationary element (locked in the housing) against which rotating friction discs rub, generating braking force.

No. This is a steel separator plate (counterplate). It does not have friction material. It serves to separate friction discs from each other.
Yes, typically the M312 model (wheeled excavator) uses the same axles as the C series. However, we always recommend checking by dimensions.
The outer diameter (across teeth) is 191 mm, and the inner diameter is 130 mm.
