This filter set provides the three primary service filters for the host machine: a hydraulic filter, an engine oil filter, and an in-line fuel filter. The hydraulic filter captures particulate from the return line to protect the pump and downstream actuators. The engine oil filter removes contaminants from the lubrication circuit to protect the crankshaft and bearing surfaces. The in-line fuel filter traps water and debris before the injection pump. All three filters are supplied together as a single kit, intended for a scheduled 50-hour or 50-month service interval. On reinstall, ensure each filter housing seal is replaced and the canister is torqued to specification.
