Description
Bosch Fiber Washer 1 230 107 011 – Thrust Washer / Serrated Washer for Ignition Distributors
The Bosch Fiber Washer 1 230 107 011 is a specially manufactured thrust and serrated washer for classic Bosch ignition distributors.
This spare part is an exclusive new edition from the original manufacturer, which differs from simple reproductions due to its correct surface structure and coating.
The fiber washer is used in the area of the distributor shaft and serves as a thrust washer for axial guidance and as wear protection between the corresponding components.
Exclusive new edition from the original manufacturer
Authentic fiber washers are of particular importance for the professional rebuild of historic Bosch ignition distributors.
In contrast to simple reproductions, this new edition features the intended serrated structure and surface coating.
These properties are important for the function and wear behavior of the thrust washer.
Important quality note:
Simple red fiber washers without the required surface structure and coating are often offered on the spare parts market.
Such reproductions do not meet the original requirements for the component and can lead to increased wear and damage to the ignition distributor.
We therefore recommend using original Bosch NOS fiber washers or high-quality new editions with the correct structure and coating.

Use and Installation
The Bosch fiber washer 1 230 107 011 is used in the area of the inner or outer distributor shaft in corresponding ignition distributor designs.
During the rebuild of an ignition distributor, the existing thrust washers should always be checked for wear, damage, and correct design.
Important: Installation requires specialist knowledge of the respective Bosch ignition distributor. In particular, the axial play of the distributor shaft must be checked according to the manufacturer’s specifications and adjusted if necessary using suitable shims.
Please compare the Bosch part number with the required spare part before purchasing. Not every Bosch ignition distributor design uses the same thrust washer.
