This is a new, genuine Kubota diesel particulate filter kit, part number 1J801-18930. Kubota’s V2403-CR-E4B engine parts book lists it as FILTER,KIT(DPF), and Kubota Engine America’s DPF chart lists it as the new DPF filter for the V2403. Kubota dealer catalogs list it for the L4060, L4701 and L4760 tractors, the MX4800, the L47 and the KX040-4 excavator. It is the filter section of the DPF muffler, which the parts list breaks into a DOC catalyst kit, this filter kit and a body kit.
The filter is replaced when it is loaded with ash that regeneration cannot burn off, when the filter element is cracked or melted, or when it is fouled with oil or coolant. Frequent regenerations, a DPF warning, low power and high exhaust back pressure are the usual signs. Find the cause before you fit a new filter. Kubota also sells this filter as a remanufactured exchange kit, 1J801-18910. That is a separate item, and this listing is the new filter.
Confirm Fitment Before You Order
Kubota uses several different DPF filter kits on the V2403, so the engine model alone will not pick the right one. The L5060, L5460, L6060, MX5200, MX5400, MX5800, MX6000 and M62 take the 1J802 kit, and the L3301, L3560 and L3901 take the 1J804 kit. Send us your machine model and serial number, your engine serial number and the number on the old filter before you order. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Kubota’s parts list shows the DPF gaskets as separate lines, 1J801-18410 or 1J801-18412. Send us your engine serial number and we will match the right one. Check the V-band brackets for stretch and heat damage. With the muffler apart, inspect the differential pressure pipes and sensor and the exhaust temperature sensors, since a blocked pipe or a bad sensor gives the same warnings as a loaded filter. Follow the Kubota workshop manual for torque and for the DPF service steps after a filter change.
