Fuel cap for Terex RT-130

The fuel cap, part number 205567, serves as the primary seal for the diesel tank on heavy machinery. It functions to close the fuel tank opening, preventing the entry of dust, water, and debris into the fuel supply. By maintaining a sealed environment, it also limits fuel evaporation and prevents accidental spills during crane operation. This component is designed to fit the Terex RT-130 rough-terrain crane model. It is compatible with equipment identified by serial number 10020.

Fuel caps are engineered to interface with the tank filler neck to ensure a secure closure. Many designs include an integrated seal or gasket to maintain pressure and a ventilation mechanism to allow air intake as fuel is consumed, which prevents the formation of a vacuum within the tank. A functional cap is necessary to protect the engine's injection system from contaminants that could otherwise lead to clogged fuel filters or damage to the pump and injectors. Ensuring the tank remains sealed is a standard maintenance practice for heavy equipment operators.
