I will be on the hard in a marina in Mobile, Alabama in a week. Among other things I want the yard to do is inspect and clean the injectors, but I think I will also order and bring to them a set of new injectors just in case. Can anyone please give me the part number for the Kubota D850 engine injectors? (I think they come in 3-pack). Big thanks!

Also, how big a job is it to replace the injectors? Do they just unscrew a new ones screw in, or does an assembly of some sort need to be removed from the top of the engine in order to get them out and back in again? If the ladder, I am assuming a particular gasket will be needed too.

It's been a while since a mechanic removed and reinstalled ours on our prior M25XP. He used a long reach type socket to remove them. New crush-washers were used to install and he always used a torque wrench for the install. The shop that tested them replaced the tips, after checking the spray patterns.
It was important to keep the area around the threads clean and clear of dirt, also.

Here are the pages for the Kubota 1550E manual (which maps to the M25 motor) showing the parts of the injector system

Thanks for the injector parts info. I’ll call my ‘local’ Kubota office on Monday and get them ordered. I’m on the Rankin dam pool in NE Mississippi but will be in a marina tomorrow on the next pool down the TTW where I’ll have WiFi and can open that up on my laptop. I’ll get them shipped to the marina in Mobile so they’ll be there when I finally get there in about 10 days.
Cheers!
