This filter set provides the replacement elements for the engine, hydraulic, and fuel systems of the host tractor at a scheduled 1000-hour service interval. The set includes the main fuel filter, in-line fuel filter, engine oil filter, hydraulic filter, suction filter, main air filter, safety air filter, and the filler cap. Each component is manufactured to the original specifications, ensuring the correct sealing surface geometry and bypass-valve cracking pressure for its respective housing. Using a complete matched set at the service interval prevents contamination from being introduced into the separate lubrication, fuel, and hydraulic circuits simultaneously.
