Iseki TH185-TH265 filters and filter set
Suitable for the entire series: Iseki TH185, TH205, TH215, TH235, TH255 and TH265. The manual distinguishes four filter types: engine oil filter, air filter element, fuel filter and hydraulic filter. For most filters, Iseki does not provide separate part codes in the factory documentation (unlike the oils, which do have explicit product codes) — below are the practically verified replacements from our catalog.
Engine oil filter
One filter type applies to the entire series, regardless of whether you have the E3112 engine (TH185/205/215) or the E3CD engine (TH235/255/265).
Engine oil filter Iseki TM | TH | SXG | SF (SKU-002/6) — explicitly matched to engine codes E3100, E3112, E3CD and E3CE. Height 73 mm, width 69 mm, thread 3/4"-16UNF.
Air filter element
The manual specifies: clean every 100 hours, replace every 600 hours or annually.
Air filter Iseki TM3160-TM3247 | TM15-TM17 | TH16-TH205 | … (SKU-20019) — this explicitly lists TH16, TH18, TH20 and TH205 as applications (outer diameter 95 mm, inner diameter 45 mm, length 185 mm). For the larger TH235/255/265 (E3CD engine block), we recommend comparing the dimensions of your current element before ordering, as no 1-to-1 confirmed SKU is available for this specific engine block within these exact model numbers.
Fuel filter
Interval: clean every 100 hours, replace every 400 hours.
For the TH185-265 itself, we have not been able to verify a 1-to-1 confirmed fuel filter SKU for the exact model number (the Iseki fuel filters available in our catalog are documented for other series such as TG6/TH5 or TM/TXG). Contact us with your fuel filter dimensions (diameter/length) or the part number on your current filter, and we'll find the right match for you.
Hydraulic filter
Note: this filter is part of the same circuit as the transmission oil (see our article on engine oil & fluids) — always replace it together with the transmission oil.
Hydraulic filter Iseki SIAL | GEAS | TK | TG | TH | TF (SKU-250012) — explicitly lists "Sial Hunter, TH18, TH19, TH20, TH22, TH24, TH205" and engine E3CE/E3CF/E390/E3100, a good match for TH185/205/215. Height 145 mm, diameter 110 mm, thread 1"1/4-12UNF.
Complete filter maintenance in one go
Prefer to do everything at once? Then combine the three items above (engine oil, air, and hydraulic filter) with fresh engine oil (see our article on engine oil & fluids) — that's the complete "minor service" for this series.
