https://www.dieselbombers.com/diesel...version-3.html Post 33 there is a picture of the Oil Pan and Oil Pick up as well as the Oil Dipstick Tube.

 

Ha ha you beat me to it! I just didn't want to drill into the block and while I was in the process of building the pan, it was easy to add the drain. Plus I wanted to have the factory dipstick. I'm not using the NPR alt (wish I did), I have the powerstroke diaphram unit. Next time it will be the NPR alt.

 

Factory Dipstick to what?

If I drill the block for the Kubota Dip Stick I can not use that as the return as it will be to small? I could be wrong but an Oil Return by itself can be no smaller than the exit of the oil return on the Turbo preferably larger by at least 1/2? Sorry I do not know sizes. But in size 10 AN works but a 12 AN is preferable.

But since you told me to forget everything gas I try and throw all that stuff out of my head.

 

The pipe reduces down above where the turbo drains to dipstick tube size, so it isn't restricted. My turbo drain is 1/2 in all the way down to the 3/4 in pipe in the pan.

 

My turbo oil returns through the valve cover, I drilled a hole in the side of it, towards the rear and installed a 5/8 barbed brass fitting. Works great.

I have drilled a bunch of oil dip stick ports in the Kubota blocks, it’s not hard you just have to pay attention and keep your drill straight. The block metal is soft and easy to drill. WARNING- as the brill bit breaks through the bottom it will grab to one side! There is a protrusion of metal that has to be drilled away once your through, not hard just be aware. All the blocks I have ever seen had a have a place on both sides of the block available for drilling, I never have but I’m sure you could use one for an oil return. I use a dip stick from a Bobcat 743, it has a rubber squeeze type seal that pushes down into the hole you drill, works independent of the oil pan.

I have the drill bit size at the house if y'all need it.

 

I just might need the Drill Bit size. But I will not know till this next week sometime when I receive the parts.

I was told by Sam that when you remove the pan you can see a flap on the inside of the block that will show where one can drill for the dip sticks? But I will not know for sure till then.

Again Thank You. And yes I will take pictures to show this stuff.

 

Not sure about drilling from the inside out, I've always drilled from the outside in. I drilled the one in the picture, see the flat undrilled spot under the injector pump.

 

Thank You for the Pictures. And Nice Paint as well. They are a GREAT Help. But it does make me wonder if I will weaken the Kubota Block by using these locations for Oil Dip Stick and Return Holes?

I did not say I was going to Drill from the Inside Out. . I was told that when you remove the pan you can see something cast into the block at the locations of the Dip Stick Locations. I am not sure what Sam was talking about until I remove the Oil Pan for a look see.

If I can use the Drivers Side for an Oil Return I will see how large of a hole I can make to install a 10 AN fitting and Y it off to the Turbo and the Return Oil for the Vacuum Pump.

I will try and Add pictures as I progress through what will be a slow project. As I really feel that there are a few Great Threads on this Conversion but are missing a great deal of detail and photos of there Conversions. If for nothing else There ideas on how things can be done. As people can use there idea or come up with a New Idea and might even be better. But Better is in the eye of the beholder.



But I must ask have you changed out your IDI Engine for the DI Engine as of yet?

 

It will not weaken the block, that's why they are there, that's where Kubota drills the holes depending on the application. You can only drill a hole approx. 3/8 or so, I will get you the specific drill bit size this weekend.

I've still not swapped over to my DI engine; I've been working on a bus project for about a year so I haven't had time. I have finished the bus now and will probably have the DI in there in the next month or so. I’m looking forward to the increase in MPG!

 

Thank You UsedKubotaMan.

By some remote chance in your Never Ending picture accumulation would you have a Picture of the Fuel Rack Limit Screw I have seen talked about to Turn it out 2 Turns?

And I also have the 2800 RPM Governor Spring Kubota Part No. 19077-56412 on the way That you gave the information for. How much did you shorten the spring to increase the RPM Range?
