Diesel Cub?

[Jeff M]

I just got home from Plain City and A guy across from us had a Cub Cadet with the starter/generator and it squeeled for 5 or 10 seconds before it wiuld turn the engine over.

Seems as though that would be due to a loose belt. Just the same, you probably wouldn't have enough grunt to spin over a diesel with the Cub s/g.

With the higher compression ratio of the diesel engine the starter/generator doesn't stand a chance in cranking the diesel engine over. I think an air starter would be neat to have if your going diesel on a cub.

Yup a loose belt on the CC would finally turn the engine over as the belt gets hot and sticky in that one spot on the pulley(friction). After a while the belt is trash. If the belt is slipping when trying to start the generator is losing charge too it has to be slipping too while running.

Some of the Yanmar 3 cylinder diesels have a cable operated compression release. I been lookin at my JD 850 and trying to imagine al the work to get that engine in a Cub, it would be very when done but man o man is that a lot of work ......... What about just converting the C-60 to diesel didn't Oldsmoble do that back in the 80's with the 350 gasser, add a few diesel componets and presto they made a diesel from a gasser.

They did convert an Olds motor gas to diesel, but that was one of the most significant lemons in the auto industry. Some of them are still out there. I saw one last week powering a Massey-Harris. However, seeing the major problems they had, I think converting the C60 would kill it. I do think putting one of the 20 hp 3 cyliners is a fantastic idea. We use a JD 870 at work and it is a pleasure. I have also considered putting in one of the tiny 4 cyl gas motors in a Cub, say from a Geo or Suzuki.

Most auto diesels were built from gassers and most were more successful than the GM. Even the early Mercedes (semi) diesel was originally a gasoline engine. At one time I had a 220 gas and a 220 diesel... same block and many other common parts.

I came across a picture of a Kubota 722 diesel engine with the starter mounted on the right side from the factory. Looks like the injector pump isn't in the way afterall.

I can't figure out how to post the picture.

E-mail the pic to me and I'll post it.

Boy would I like to have that setting in my garage.

This is a fascinating thread! Before I got too excited about the Kubota 722, I'd do a little more checking. Maybe Marketing just turned the picture around so it would look prettier.

My Kubota has the injectors on the right side but it's not here to check the starter location. Never had a reason to check until now Grump

Actually, the Olds diesel engine wasn't the lemon most make it out to be. It suffered from a poor understanding of diesel engine needs by the consumer and the GM automobile dealer network's inability to service and troubleshoot problems. Most of the engine's demons stemmed from dirt and water in the fuel making it's way into precision components and the wrong service type oil in the crankcase. No water seperator, lousy fuel filter, owner abuse, repair shop mistakes, poor maintenance, crappy diesel fuel - the list goes on and on - this particular engine died of neglect straight from the factory. The design was good, application was horrible. Similar to the Edsel's unfounded reputation, it also was unfairly sentenced to death by design and marketing.

I can think of genuine fiascos, like the Vega's incredible melting aluminum engine and Cadillac's V8-6-4 clunker.

I'm anxious to see a Cub diesel conversion, it's gonna be a work of art!

I have a vw 1.6 diesel block and & bellhousing separated that I'll bring to Cecil's.

If there is tractor apart somewhere - we can line up the components - and then do some collective head scratchin.

Maybe it isn't such a crazy notion as all that.

like the cub, there are lots and lots of these machines out there, and parts are available and reasonable.

nice torquey little critters

sure would be nice to have a bit more oomph behind the flail mower most of the time

The conversion I would like to see is a Continental Y-69 off an IH baler or combine installed in a Cub. Since IH replaced the Y-69 with the C-60 in its balers and combines, it would be neat to see one running side by side with a C-60 in a tractor. Yes I know the Cont. has 9 more CI's but what would that amount to in actual performance? I still say IH could have designed, built, and sold the Cub more economically since they wouldn't have had to develop another mag, carb, and other components from scratch.

As to the "diesel" Cub, other than the pride and fun of seeing if it could be done, you would still have a three speed transmission, non-standard hitch and PTO, and the tendency to break finals and other major castings. I would rather go ahead and buy a nice newer compact tractor and be done with it.
