Universal Fuel Injector Replacement (not rebuild)
- Thread starter Jtcf78911

You can have the old ones rebuilt for much less $$. Look around for a tractor repair shop or a shop that specializes in diesel engines. Any good shop will test them for you and let you know if they need to be rebuilt. You can take them to any Kubota dealer for rebuild, but they usually don't have the capability and will just ship them to someone that can. Cut out the middleman and take them yourself.
Here's a link to an online tractor shop and the injector you need. Or go to your local Kubota shop and ask for parts for your G3200 tractor. Same exact parts for maybe 1/10th the price. Do NOT, under any circumstances, buy any parts through the Westerbeke / Universal parts system.
The only parts on the engine you cannot get from the tractor shop are the exhaust manifold and raw water pump. The pump can be gotten much cheaper from other sources like Depco pump, and if you need the manifold you're just SOL.

I was just going to say what Kloudie replied. That's where I got it too. I also did a Cortana search "what tractor is the Kubota Z400 engine used in" and got the same answer. If its on the internet it must be true!
I used a deep socket (metric, I don't remember the size) and a breaker bar to get mine out. There's a thick copper crush washer under the nozzle that needs to come out, if it stays in the hole you can fish it out with a piece of wire. The new nozzles should come with new washers.

Tom, we've been telling people with Kubota tractor engines in their boats this same thing for the past 30 years.
What's not to like?
Kubota equivalents
The nozzles in particular are aftermarket items. Universal doesn't make them and neither does Kubota. They're actually made by Denso and the wholesale price appears to be around thirty or forty dollars. Kubota and the independent parts suppliers buy them and add whatever markup they want. It just happens that Universals markup is about 300%. All they do is put their own label on the box. It's the same as the parts Kubota does make, Universal buys them like anyone else and relabels them. Those are very expensive labels, and that's all you're getting for the money. As long as people keep paying the price, they will keep doing it.
Tom.Actually the 5411, aka M-15, is a Z500 engine out of a B5100 tractor. It's real similar to the Z400 just a little higher displacement. (The 400 and 500 are the cubic centimeter displacements.) I'm pretty sure they use the same injector nozzles though. I've looked through the parts books for various Kubota engines and they all show different part numbers, but when you search the numbers at a supplier they list one part that replaces all of them. When you get into their bigger engines the replacement numbers are different and the actual parts look different. There are quite a few parts that are shared between multiple models.
Hey all. I know you weren't sleeping on this...my new Kubota injectors are now in place and job was pretty straightforward. Quick question - I've read that I would need to bleed fuel system after this work - but manual says M-12 is self bleeding and is sans bleeding instructions. Thanks in advance. T.
Don't believe it. Turn off the water intake, leave the injector pipes a little loose at the nozzles, and crank until fuel squirts out with no bubbles. Tighten the pipes back up and she should start right up. Don't forget to open the water intake again.
Extended cranking with the water on can flood the muffler and get water into the cylinders. If it starts right away there's no risk, but you don't know until you try it.
Unless yours has the electric lift pump. (My 5411 doesn't). If its electric just turn it on till the fuel flows out. No need to crank, no risk of flooding.
