Kubota Hydraulic Filter Replaces HH330-82630 33960-82630 SBA340500720 WIX 57098

Match your current filter’s part number or your parts manual to one of these numbers: HH330-82630, 33960-82630, 32590-38380, SBA340500720, HHTA0-37710, T0070-37710, TA040-37710 (WIX 57098).

No, this is an aftermarket replacement that interchanges to the OEM numbers listed.

Common symptoms include slow or weak hydraulics, jerky loader/3-point movement, pump whining/noise, overheating hydraulic oil, foamy/aerated fluid, or performance that gets worse after the machine warms up. A clogged filter can restrict flow and make the pump work harder. If you replace the filter and symptoms remain, check hydraulic fluid condition/level and any suction screen or strainer (if your model has one) per your service manual.

Follow your machine’s maintenance schedule because intervals vary by model and how hard it’s used. Many machines replace the hydraulic filter at set service intervals and/or when hydraulic fluid is serviced. Heavy use, dirty environments, or unknown service history can justify earlier replacement. The safest method is to use your manual’s hour interval for your exact model.

Only if the fluid clearly meets the Kubota spec listed in your manual (often Kubota UDT / Super UDT requirements depending on machine). “Universal” fluids are not all the same—if the label does not explicitly state it meets the required Kubota specification, don’t use it. Using the wrong fluid can cause noise, poor performance in cold weather, and long-term wear.

No. Hydraulic filters are built for different flow rates, filtration requirements, and bypass valve settings than engine oil filters. Using the wrong type can restrict flow or bypass incorrectly and may lead to poor hydraulic performance or damage over time. Always match the correct hydraulic filter part number for your application.

Make sure the old gasket comes off with the old filter, then clean the mounting surface. Lightly oil the new gasket, spin on until the gasket touches, then tighten by hand per typical spin-on procedure (don’t overtighten). After installation, start the machine, cycle hydraulics, check carefully for leaks, and recheck fluid level. If your system was low or air entered the system, follow your manual’s steps for bleeding/priming.

Color/label and even small design details can vary by manufacturer or production revision. What matters is the part number match. If your current filter number matches one of these interchange numbers (HH330-82630, 33960-82630, 32590-38380, SBA340500720, HHTA0-37710, T0070-37710, TA040-37710 / WIX 57098), it’s typically the correct replacement. If your machine has been modified or you’re unsure, confirm with your parts manual.
