Installation Notes

Filter element replacement is typically performed by a diesel technician or heavy-equipment mechanic during scheduled maintenance intervals. Before servicing, shut down the engine and allow it to cool. Inspect the housing and sealing surfaces for cracks or debris before installing the new element, and confirm the molded urethane ends seat fully against the housing faces. Follow the equipment manufacturer service manual for torque specifications on housing hardware and any applicable inspection requirements.
