Good To Know
Q: How often should I change this hydraulic oil filter for Case? A: Change it at every hydraulic oil service interval specified in your machine's manual, typically every 500 to 1000 hours depending on operating conditions.
Q: Can I use this filter for multiple Case models? A: Yes, it fits the listed Case models, but verify your serial number range to ensure the same thread size and bypass setting.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
