Kubota D1803-CR, V2403-CR, L3901, L4701, MX5200, KX040-4 & KX057-4 DPF Gasket | Genuine Kubota 1J801-18412
This is the genuine Kubota DPF gasket, part number 1J801-18412. It seals the joints of the DPF muffler where the catalyst, the filter and the body clamp together. Kubota engine catalogs list it for the common rail D1803, V2403 and V3307, and Kubota dealers list it for the L3301, L3901, L3560, L4060, L4701, L4760, L6060, MX4800, MX5200, MX5400, MX6000 and LX3310 tractors, the KX040-4, KX057-4, U48-5 and U55-4 excavators and the R430 and R530 loaders. It replaces 1J801-18410.
Fit new gaskets any time the DPF muffler comes apart for a filter clean or a filter change. A used gasket leaks soot at the clamp and can upset the pressure reading across the filter.
