Frequently asked questions
How do I confirm this filter fits my specific machine?
Check your existing filter's dimensions (height 450 mm, outer diameter 150 mm, inner diameter 110 mm) and cross-reference with the brands listed. If your filter matches these specs and is used on Komatsu or New Holland equipment, this aftermarket filter is a direct replacement.
What is the filtration rating and media type?
The product specifications do not include a specific micron rating or media type. For detailed filtration performance data, please contact our support team. The filter is built to the original dimensions and ratings for the listed cross-references.
Will the thread size and sealing surface match my housing?
The largest inner diameter is 110 mm and largest outer diameter is 150 mm, which typically correspond to standard mounting configurations. However, we recommend comparing these dimensions with your original filter to ensure a proper seal and fit.
Is this an OEM part or a generic aftermarket filter?
This is an aftermarket filter, not an OEM part. It is designed as a direct replacement for filters from Donaldson, Fai Filtri, Fleetguard, HiFi Filter, Komatsu, New Holland, Oxfil, Samsung, and WIX, built to match their specifications.
How do I install this filter?
Installation is similar to standard hydraulic filters. Ensure the system is depressurized, remove the old filter, clean the mounting surface, lubricate the gasket, and tighten the new filter by hand. Do not use tools to avoid overtightening.
