Precise 1217634 steel separator plate from the FEROSTEM range. This is a 2.5 mm thick brake system friction component, dedicated to drive axles and final drives of Caterpillar (CAT) and Volvo wheeled excavators. The disc features 67 external teeth, ensuring perfect engagement with the housing and efficient braking force transfer.
FEROSTEM products guarantee maintenance of factory operating parameters. Steel plates undergo special treatment to withstand extreme loads and temperatures, ensuring proper alignment and torque distribution in the axle.
| Brand | Excavator Models |
|---|---|
| Caterpillar (Wheeled) | M312, M313C, M315, M315C, M316C, M318 |
| Volvo | Selected excavator models (please check dimensions) |
Disc dimensions (191x130x2.5mm) are decisive. Please verify before purchasing, as 3mm discs also exist in the same axles.
Steel plate 1217634 works in a pack with friction discs. When overhauling the axle, it is recommended to replace the entire set and seals, as well as filling the system with fresh transmission oil.
Using a separator plate of incorrect thickness (e.g., 2.5 mm instead of 3 mm or vice versa) will disrupt the brake working clearance. This can lead to brake failure or permanent wheel locking and axle overheating.
Plate 1217634 acts as a separator, spacing friction discs apart and transmitting braking torque to the axle housing.

The main difference is thickness. Disc 1217634 is 2.5 mm thick, while 11705007 is 3 mm thick. Other dimensions (diameters, tooth count) are usually identical.
The quantity depends on the axle configuration. Typically, there are several (e.g., 3-5) steel separator plates per side. Check your machine's parts catalog.
No. This is a steel separator plate (counterplate). It does not have friction material. It serves to separate friction discs from each other.
