This is a new, genuine Kubota diesel particulate filter kit, part number 1J070-18930. Kubota’s parts list calls it FILTER,KIT(DPF), and Kubota Engine America’s DPF chart lists it as the new DPF filter for the V1505. Kubota dealer catalogs list it for the LX3310, LX3520 and LX4020 tractors, the F3710 front mower and the ZD1611 mowers. 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 Engine America’s chart also lists a cleaned exchange kit for this filter, 1J070-18910. That is a separate item, and this listing is the new filter.

Specifications

Fits / Applications

• Kubota V1505 diesel with a DPF
• Kubota LX3310 tractors (HSD, HSDC)
• Kubota LX3520 tractors (DTN, HSD, HSDC, SUHSDC)
• Kubota LX4020 tractors (HSD, HSDC)
• Kubota F3710 front mower
• Kubota ZD1611 mowers (LF, RL, RLF)

Use new DPF gaskets and check the V-band bracket for stretch and heat damage. With the muffler apart, inspect the differential pressure pipes, hoses 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.
