This is a new, genuine Kubota crankcase breather filter element kit, part number 1J770-05810. Kubota’s parts books call it ELEMENT,KIT and show it in the oil separator group. Dealers also call it the oil separator element or the CCV element kit. It is the small filter inside the oil separator, the part that takes oil mist out of the crankcase blow-by gas. Kubota’s engine parts books list it for the common-rail D1803, V2403 and V3307, and dealer catalogs also list it for the V2607.

Kubota dealer catalogs list it across the L, MX, M, KX, U, R, SVL and SSV lines, for example the L3901, MX5400, M7060, KX057-5, SVL75-2 and SSV75. The full list is below. A plugged element raises crankcase pressure, which can push oil past seals. This is not the fuel, oil or air filter, so match the number on your old kit or have the machine model and serial number ready.

Frequently Asked Questions

What does the Kubota 1J770-05810 kit do?

It is the filter element for the oil separator in the closed crankcase ventilation system. It takes oil mist out of the blow-by gas before the gas goes back to the intake.

Which engines and machines use the 1J770-05810?

Kubota parts books and dealer catalogs list it for D1803, V2403, V2607 and V3307 engines with the oil separator, in machines such as the L3901, MX5400, M7060, KX057-5, SVL75-2 and SSV75. Call 530-668-0818 with your machine or engine serial number and we will confirm it.

Do I need the separator O-ring too?

Kubota lists the separator O-ring as its own part, 1J770-05130. If yours is hard or cut, order it along with the element kit.

Is this the same as the fuel filter or oil filter?

No. It is a separate, small element that only cleans crankcase blow-by gas. The fuel and oil filters have their own Kubota numbers.
