May have bbeen covered in one of Ron Hill's Tech Notes, but for your information:

Question:

I have an M25 Universal and believe it is a D850 Kabota. I have the Universal manuals and know the Universal Part Numbers for the fuel injectors I am looking to replace. When I call various Kabota dealers they won't help unless I know the Kabota part numbers. The Universal numbers are 298787 and 298788. Can anyone help?

Answer:

The injectors are Nippon Denso injectors, i.e., not made by Kubota. The number on the ones I removed was 093500-1560 (the ones I installed are -1570 - I don't know what the difference is).

The reason for two different Universal P/Ns is a banjo nut for the fuel return with either one or two nipples. No matter, since this part won't come with the new Denso injectos, just use the old ones over again.

Universal price is about $200. Rebuild cost quoted locally is $84.00. I bought my replacements for $73.00, LESS than the cost of rebuilding the old ones! Search the web.
