Turbo time!
 

As I had mentioned in the post of the initial build, my plan was to run a few hours shake down and then install a turbo on my 782D. The time has come! I hope that this will be completed in a reasonable amount of time, and I will take pictures of the progress. So here we go -----

EDIT - I should add the the kit was purchased from OCC member Mike Masharis. The kit is very well thought out and even comes with a short description of someones experience installing the kit. Thanks Mike!

:popcorn: Let the fun begin.

:popcorn::popcorn::ThumbsUp:

You have way too much fun, Doc. I have never heard a Cub Whistle before in person. Now I know I'm gonna have to take a drive someday! :beerchug:

Turbo Time
 

Looks like your in it for the long haul. Got some questions- did you source the components yourself or purchase in a kit? What is the projected power result when installed? Have you beefed up the driveline? the drive shaft and joints- if you did what did you change up to?
Looks like a cool project- I will be watching with envy. Please keep the pictures coming as you go!

Had a racer friend that had this on a tee shirt. :biggrin2:

No need to beef up the driveline on a hydro. Only so much power can go through a hydro, and only takes so much power to drive one. Turbo will help with the load on the PTO, but won't really affect drive power.

Pete I have two whistlers here if you want to here one.It was one of my kits.

you got my attention, but I want to run it for a while and see how things shake out. I still have a few items to address before I can put the hammer down and see how it performs. Could you send me a pm with the kit specifics?
thanks-pete

Regardless of whether the driveline needed to be beefed up or not, I did make improvements. I installed a hydro with the splined input shaft from a Cyclops along with the CV style drive shaft. The adapter at the motor end was supplied by Jeff in PA. The shaft had to be shortened by about 6 inches so I turned a 4 inch long coupler with .750 ID on the lathe then welded it in the middle saving both splined ends of the Cyclops driveshaft. It makes for a nice clean installation and no more spirol pins to worry about.

The first item of business today was to remove the stock exhaust components from the Kubota. The exhaust extension also supports the belt tensioner for the cooling fan so this will need to be modified later in the project.

Next step was to install the adapter plate for the exhaust manifold. The exhaust ports are on the same centers but the stud pattern is different. Countersunk bolts allow the plate to be fastened head, then the turbo and it's manifold bolt onto the adapter.

Once the turbo is installed onto the motor, lube oil must be plumbed to and from the housing. The source for the oil is drawn from a tee fitting installed at the oil pressure sending unit. The drain oil will be piped around to the other side of the block and dumped at the location where a mechanical fuel transfer pump would be installed if used. On a 782D, there is an electrical fuel transfer pump so the engine block has a block off plate. A fitting will be installed there for the drain. The installation of the drain hose will be first on the list tomorrow.

I'm impressed. Drive shaft came out sweet!

Yes it did Sam, and thank you for your guidance. I really like the strength/integrity of the CV style joint. The boots are still available from Cub too. Reasonably priced at $16 a piece. :Thanks:

I think the early 782D's & 882's had the mechanical & electrical fuel pumps. Here is a pic of one of mine with it. I guess I could remove the mechanical one if needed.

Everything looks good so far. Keep the pics coming doc!:beerchug:

What parts did you use for your CV drive shaft?

It's basically a hydro and a driveline from an 1864. That gives you the splined input on the hydro and the CV type shaft. The shaft is too long and needs to be cut and spliced in the middle. The CV to Kubota front pulley adapter is available from OCC member Jeff in PA.

Turbo time!!
 

Your efforts are marvelous! Great work- everything is looking top notch! Very interested in seeing and hearing the end results. Smoke tomorrow??

We left off with needing to run the oil return line from the turbo to the other side of the motor and attach it onto the block where a mechanical lift pump would be if this had one. After removing the plate and installing the fitting supplied with the kit, I ran the return hose around the back of the motor and connected it to the fitting. I made sure to position the hose so that it is a downhill run from turbo to block to eliminate any puddling of oil in the hose.

Next up was installing the air piping to and from the turbo. The original air inlet tube was cut in half to create an elbow, then the air tubing was routed around and into the turbo. The boost air from the turbo to the intake manifold passes over the valve cover. On the Kubota, the engine oil fill has an extension that must be removed to lower the fill cap so that the air tube can pass over it.
I stopped at this point and ordered a reducing elbow to go from the turbo to the air crossover pipe. One is 1 1/8" and the tube is 1 1/2". I think that will make for a cleaner installation.
Pegasus Auto Racing has a huge selection and is a great source of specialties like the silicone hose elbow.

Like I said, you are having good way too much fun....:beerchug::beerchug: Looks great, Doc!

One of the biggest obstacles to over come will be the exhaust from the turbo to the stack. I am going to try and exit the engine compartment thru the original passage in the side cowl. I ordered a couple of close radius U bend tubes used in making race car headers from Jegs.
http://www.jegs.com/c/Exhaust-System...0002&langId=-1 They can be cut and welded to create the snake that I need!

Once the exhaust is built I will modify the factory exhaust support and reinstall the belt tensioner.

You know Doc you are making it very tempting to put one on my 1512.

It's a very well engineered kit, and simple to install. Mike M. did a great job putting this together. All the hard work is done. :IH Trusted Hand:

Jeepers, that's a very clean looking install so far, good work Doc.:beerchug:
Makes me want one. But I need a smoker first.:bigthink:

Very nice work! :beerchug:

I can't believe it but the UPS man has already dropped off the turbo hoses and the exhaust tubing I ordered on Tuesday. Fast shipping! The turbo hose was just a matter of slipping it in place. I still need to buy a couple more clamps. As for the exhaust, I sectioned the two U bends into different angles I needed to bring the exhaust out the original opening in the side panel. About two hours of cutting, grinding, tack weld, cut, grind, tack weld (you get the picture) and I finally had something that would work. I have one more item to complete. I need to build a bracket for the belt tensioner as the original was attached to the exhaust spacer. Maybe smoke and whistle tomorrow! I'd be interested in hearing what everyone thinks I should do for the stack. Leave it as it is now, taller, tip out, chromed, etc. What should I do?

Looks great. I like the exhaust. Well done. Drive it around and evaluate if smoke gets in your eyes. May have to elevate the stack.

I think it looks great, but I believe you will have to do an operational evaluation of your exhaust - smoke in the eyes is not good. Will you be doing a video of some HOT laps around your property? I am sure everyone is very interested in how it performs. Nice work!

An impressive tractor! :beer2:

That is a great looking tractor Stan. You have been very busy.

You will want to divert the exhaust to the front or side the noise at ear level is bad .Been there .May think about a stack brace also a lot of stack wobbling around.

Thanks for the sage advice Mike. I plan to make a mount for the belt tensioner today and then possibly add a brace from that to the exhaust stack to cut down on vibration.

My Yanmar turbo has the exhaust come out of the turbo,
in to a small muffler,
then, down towards the ground.

I REALLY like not having branches try to take off the exhaust pipe!! :bigthink:

AND,,, it ALL fits under the hood! :biggrin2:

John I think you posted on the wrong forum, you need to go to WFM. They are all into that green stuff. LMAO :biggrin2:

I think all of the Yanmars are the same color underneath,,, :biggrin2:

:ExtremeFunny:

Saw this at a show, they did a good job. (Sorry about the size, can't get it any bigger)

Last thing on the to do list was to make a mount for the belt tensioner on the cooling fan. Using the original mount as a drill pattern, I drilled the holes in a piece of 1/4" x 2 1/2" x 4 1/2" flat stock. That put the tensioner right back in it's original position.

The beast runs! I took Mike's advice and added a tip out to the top of the stack. That tamed the noise and got the smoke headed away from the operator. As soon as it quits raining and I figure out how to post a video I'd take from my cell phone, I'll post one of it running. Thanks to everyone for your kind comments. This was a fun build.
