Locking fuel tank cap for Liebherr 916

The locking tank cap, part number 7610826, serves as the closure for the filler neck of a tank on heavy machinery. Its primary function is to seal the opening to prevent the ingress of dust, water, debris, and other contaminants that could compromise the integrity of the fuel or hydraulic systems. The integrated locking mechanism provides security by restricting access to the tank contents, which helps prevent fuel theft and unauthorized tampering with the machine fluids.

This component is designed for use on the Liebherr 916 excavator. The design ensures a precise fit to the filler neck to maintain the required sealing pressure and security standards for this specific model. By maintaining a secure and airtight seal, the cap supports the operational cleanliness of the fluid circuits and protects the machine from external interference.

Tank caps for heavy equipment typically incorporate a sealing gasket or elastomer ring to ensure a tight fit against the filler neck. The locking cylinder is designed to withstand environmental exposure while providing a reliable interface for the operator to secure the tank. A properly functioning cap is necessary to prevent fluid contamination and loss, which are common causes of system failure and increased maintenance requirements in construction and mining applications.
