The list above is for reference. This gasket fits most common JCB machines. Visual verification and part number are key.
The hydraulic system is extremely sensitive to contamination. Before opening the filter cover, you must thoroughly clean the entire top surface of the tank. Allowing even the smallest amount of dirt to enter the oil can cause catastrophic failure of the hydraulic pump or valve blocks.
This gasket provides an airtight seal for the hydraulic tank at the filter access port. It prevents oil leaks and, more importantly, the ingress of water, dust, and dirt into the system.

Yes, it is absolutely necessary. The old gasket is compressed and hardened by heat and pressure. Reusing it will almost certainly cause a hydraulic oil leak or, worse, allow dirt to enter the tank, which can destroy the main pump.
2. Does this gasket fit the fuel cap?No. The alternative numbers (331/45908, 331/33064) listed in some catalogues are incorrect and refer to a fuel cap. This gasket (813/00466) is exclusively for the hydraulic tank filter cover.
