Kubota GB110-GB200 filters replacement
Kubota GB110-GB200 filters: part numbers and intervals
The filters of your Kubota GB replacing them is the most rewarding maintenance you can do: cheap, quick, and it prevents the most common faults. Below you'll find all filters for the series with the original Kubota part numbers from the manuals, the intervals, and what to look out for.
Suitable for the whole series: Kubota GB110, GB130, GB140, GB150, GB160, GB170, GB180 and GB200.
Kubota GB filter overview with original numbers
The OEM numbers below come directly from the consumable parts list in the Kubota manuals. Use them as a reference when ordering. Please note: a ready-made filter kit specifically for the GB110-GB200 does not (yet) exist — the filter kits in the shop are put together for the older B and GB15/GB20 series, which have a different air filter. So for this series, order the individual filters below; each one has been matched to the correct OEM numbers.

| Air filter element | All (single element) | 6A100-8263-0 | Clean every 100 hours; replace annually or after 6× cleaning |

| Fuel filter | All — complete (glass bowl + element) | 6A320-5886-0 | Replace element every 400 hours |

Kubota GB air filter: dry element, so never oil it
All GB models have a dry paper air filter element. At the 100-hour service, blow it clean from the inside out with compressed air at a maximum of 5 bar, keeping the nozzle at a distance from the element. Never tap it out (the element deforms, allowing dust to enter the engine past the filter) and never dip it in oil. Always fit the dust cap with the arrow pointing upward, and empty the evacuator valve at the bottom. A clogged air filter can be recognized by loss of power and black or white smoke.
Kubota GB fuel filter: the source of most starting problems
The fuel filter sits in a transparent bowl under the tank. Dirt, water, and bacterial growth in old diesel collect here first — so check through it at every service. After replacing the element, the fuel system must be bled. Also check the O-ring on the filter bowl: a dried-out O-ring draws in false air and causes exactly the same symptoms as an empty tank (stuttering, stalling, not starting).
Kubota GB oil filter and hydraulic filter: don't mix them up
Please note: the engine oil filter and the hydraulic filter on this series are both spin-on filters that look similar, but they are absolutely not interchangeable. The hydraulic filter (in the transmission circuit) has a different construction and opening than the engine oil filter. If in doubt, always check the OEM number on the old filter. The F versions of the GB160/180/200 also have a second, different filter for the CVT transmission.
