Euros Kubota ZD323 ZD331 ZD326 Maintenance Filter Kit K3181-82240 — Full Engine, Fuel & Hydraulic Set

Euros K3181-82240 is a complete maintenance filter kit that replaces primary and secondary air filters, oil, fuel, HST and hydraulic filters for Kubota ZD323, ZD331 and ZD326 mowers.

Keep mower systems running cleanly with a matched set of filters designed to replace the factory references listed for the Kubota models above. This Euros maintenance kit groups the parts you regularly change—primary and secondary air filters, oil and hydraulic filters, HST filter and two fuel filters—so scheduled service is faster and you avoid mismatched components. Each element is offered to fit the specified OEM numbers, simplifying upkeep for commercial and residential mowing equipment.

Which original parts does this kit replace?

This kit is assembled to match multiple OEM part numbers commonly used on Kubota ZD series mowers. It covers both air stages plus engine and fluid filtration so you can do a comprehensive service in one visit.

• Primary air filter: replaces K3181-82240
• Secondary air filter: replaces K3181-82250
• Oil filter: replaces HH150-32094
• HST filters: replaces HHK70-14073 / HHK70-14070
• Hydraulic filter: replaces HHK32-16770 / HH3A0-82630
• Fuel filters: replace 12581-43012 (two included)

How will installing this kit affect mower performance?

Replacing worn filters prevents excessive dust, debris and contaminants from entering engine and hydraulic systems, helping maintain power delivery and hydraulic responsiveness. While filters don’t increase engine output, fresh filtration helps preserve component life and consistent operation under load.

• Restores proper air flow to the engine by replacing both air stages
• Removes contaminants from fuel and oil to protect injectors and bearings
• Maintains HST and hydraulic cleanliness for smoother steering and lift functions

What’s included in the Euros maintenance kit and why it matters?

The kit contains every filter you’ll typically change at scheduled service intervals for the specified Kubota models. Having matched filters on hand reduces downtime and the risk of installing incorrect replacements during a field service visit.

• 1 primary air filter + 1 secondary air filter for staged filtration
• 1 oil filter and 1 HST filter to protect engine and transmission fluids
• 1 hydraulic filter to safeguard hydraulic pumps and valves
• 2 fuel filters to ensure clean fuel delivery and easier fuel system maintenance

How do I confirm this kit fits my mower?

Check your mower’s service manual or the existing filters for the OEM reference numbers listed on the packaging. The Euros kit was matched to commonly used Kubota part numbers—confirming those numbers ensures correct fitment before purchase.

• Compare part numbers printed on your current filters to the replacements in this kit
• Verify compatibility with Kubota ZD323, ZD331 and ZD326 mower models
• Contact seller support if you need help matching a specific serial or part variant

Who is this kit for? Technicians, groundskeepers and equipment owners who service Kubota ZD series ride-on mowers and prefer the convenience of a single purchase for routine maintenance will find this Euros kit useful. It’s designed for scheduled maintenance intervals where replacing air, fuel, oil, HST and hydraulic filters together reduces service time and helps maintain system reliability. If you need full-set filtration aligned to the OEM numbers listed, this kit provides the matched components for an efficient service.
