Technical Specification and Compatibility

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.

Part Number: 11705007
Component Type: Steel Separator Plate / Counterplate
Outer Diameter: 191 mm
Inner Diameter: 130 mm
Thickness: 3 mm
Tooth Count: 67 (External / EXT TH)
Material: Steel
Manufacturer: FEROSTEM

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.

Features of FEROSTEM 11705007 Plate

Precision Spline: 67 external teeth ensure excellent engagement in the axle housing, distributing braking forces over a large area.
High-Grade Steel: Material resistant to warping under high temperatures generated in the braking system.
Optimal Surface: Smooth surface structure cooperates with friction discs, ensuring effective braking and minimizing lining wear.
3mm Thickness: Standard thickness for intermediate plates in this type of axles, providing the correct distance between friction discs.

Application in machinery

Brand Excavator Models
Caterpillar (Wheeled Excavators) M312, M313C, M315, M315C, M316C, M318, M318C
Volvo Select wheeled excavator models (check dimensions)

The above list is for reference. Before purchasing, please verify dimensions (191 mm x 67 teeth) and axle part number.

Related Parts and Hardware

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.

⚠️ Safety Warning

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.

Part Role in the Machine and Failure Diagnostics

Plate 11705007 is a stationary element (locked in the housing) against which rotating friction discs rub, generating braking force.

  • › Axle overheating (residual friction due to warped plates).
  • › Purple discoloration (sign of steel overheating - plate to be replaced).
  • › Decreased braking efficiency (surface too smooth).
  • › Deep scratches and pits (damage by filings).

🔧 Expert Guide: Key Installation Tips

  1. Tooth Count: Count the teeth! This plate has 67. Similar plates exist with a different tooth count that won't fit the housing.
  2. Flatness Test: Place the new plate on a glass surface. If it wobbles, do not install it. It must be perfectly flat.
  3. Oil: When assembling the pack, lubricate every steel plate and friction disc with clean oil.

Frequently Asked Questions (FAQ)

Is this a friction disc?

No. This is a steel separator plate (counterplate). It does not have friction material. It serves to separate friction discs from each other.

Does it fit M312?

Yes, typically the M312 model (wheeled excavator) uses the same axles as the C series. However, we always recommend checking by dimensions.

What is the diameter?

The outer diameter (across teeth) is 191 mm, and the inner diameter is 130 mm.
