Typical applications in the nautical field

The thrust washer is a component that falls within the logic of spare parts for Sail Drive transmissions and for assembly/disassembly and restoration operations during maintenance. In particular, it is considered in operations where it is necessary to replace parts subject to wear, damage or deterioration over time, especially when working on groups that require correct fitting and careful placement of components.

When replacement may be required

• Scheduled maintenance interventions on Sail Drive and connected components.
• Restorations following disassembly for inspection or overhaul.
• Replacement during work on adjacent parts, when it is preferred to renew components related to assembly.

Operational advantages (from a maintenance perspective)

The main objective is to offer an identifiable component consistent with workshop needs. This thrust washer, offered as a compatible replacement, can be useful for those who want:

• Reduce downtime during maintenance interventions by having a dedicated and coded spare part.
• Manage spare parts in an orderly manner thanks to clear references (code 4050044 and indicated original reference).
• Support maintenance of the indicated Sail Drive engines and groups, maintaining consistency with the variants listed in the datasheet.

As with all spare parts, the final performance depends on the correct selection of the component, the condition of the assembly being worked on, and the quality of the installation.
