Diesel swaps are becoming more common every day. The advantages are obvious to anyone who understands the basics of automotive technology. Diesels are more robust, produce more low-end torque, and offer higher fuel mileage than comparably sized gasoline or petrol, as they call it every else but here in the USA engines.
Well, first of all, most diesel swaps are not easy. In addition to that, depending on where you live, a diesel swap may make the truck difficult to get registered. There are a few options. One of the more common is the Cummins 4BT a four-cylinder variant of the 6BT found in Ram trucks that has been successfully swapped into a wide range of vehicles.
To get the low down this Kubota diesel engine, we contacted them about their experiences. Kubota Facts. My most important piece of advice would be to take lots of measurements. The VDI is an inline four-cylinder, four-stroke diesel with a displacement of 2, cc cubic inchesand depending on the model number, has a bhp rating of between 30 and 36 at around 2, rpm. They weigh right around pounds roughly half of a 4BTand have a Our first source had some experience working on the Kubota and knew it to be a reliable engine.
Before he started, he read every online forum about swapping these engines that he could find. He pulled out the engine, then stripped the wiring harness down to just what he needed to make the new engine start, run, and make the gauges work.
Then he took measurements on the engine for the flywheel depth the rear of the engine to the flywheel facediameter of the flywheel, inside diameter of the flywheel face, and the pilot bearing hole. Factoring in the one-inch adapter plate, he was able to calculate how much to take off the flywheel so it would fit in the bell housing and have the proper depth for the throw-out bearing. He took the flywheel to a local engine shop to have it machined. DetroitDiesel drilled and tapped the Kubota's crank end left to accept a new pulley.
Bali beach font also had to make an oil fill port center with cap on in the Kubota's valve cover.Discussion in ' Flat Fender Tech ' started by garage gnomeJun 27, Log in or Sign up.

Only question I have, and maybe you guys can shed some light on it is, the kubota only revs up to rpm. The L head will go up to rpm or so. I was curious how the lack of rpms would effect my jeeps wheeling ability.
Would the added torque make it so I would be able to use a higher gear? My jeep has a T18 and overdrive, so I have 8 gear choices. Lots of times in say mud, 2nd is too low and 3rd doesn't give me enough wheel speed but 2nd od is perfect. I've heard 25mpg.

GlennJun 27, Joined: Mar 21, Messages: 1, I would think you'd need to go to taller gears in the diff's to compensate for the lack of rpm. Otherwise you would have a pretty low top speed. The kubota diesel would have about the same 60hp that the flathead has. The higher torque is what allows the diesel to make 60 hp at a lower RPM and throught the 0-redline range it will feel significantly stronger than the l-headbut its still the same 60 hp, and will still only be able to push the jeep against the wind with the same amount of force.
It will be more efficient and way stronger around town though. Joined: Aug 10, Messages: 20, Right - power is what overcomes drag. Torque gives you acceleration. It would be a fun project. However, I'd think you'd be better off with the VW 1. The Kubota is from a reefer unit or something like that, is it not?Forum Rules. Home Forums Reviews Articles Store.

Looking for a replacement D engine is analogous to finding a needle in the haystack. However there are a lot of Kubota D, D and D engines available both new and remanufactured. Is it possible to swap any of these into the ZD21 mower? Yes, I checked with Kubota and their conservative answer is "the D is the only engine tested for use on the ZD21", but the brochure for the ZD21 also lists the ZD28 and they share a majority of parts.
The ZD28 comes with a D Last edited by ejbeaulieu; at PM. I would check the overall dimensions to make sure the new engine will physically fit im the mower, and flywheel connections to make sure the drive line will be compatible, the rest is linkage and such.
You can even make adapter plates for the driveline if needed. The question is, is the mower worth the hassle and expense? There you will find dimensioned engine drawings.
This should help answer your questions. Looking at the Kubota web site and the service manual, I think I can find a way to make a swap. I may have to replace the mounting brackets but it should fit.

Dad and I rebuilt the L-head engine in It still runs good but it will be nice to have more torque which I am sure the diesel upgrade will provide.
I apologize in advance to anyone who is offended by my blatant disregard for originality. My Dad believed in upgrading for safety and reliability.
The Jeep has 11 inch brakes, 12 volt electrical, a Warn overdrive, seat belts and an auxiliary gas tank so despite appearances, it is not stock anyway. I bought a used V engine and have been working on it to get it ready for the transplant. Greg at Overland Diesel sold me the conversion kit and the turbo kit and the later model bell housing.
Here are pictures of the Jeep, the engine as I received it, the engine all cleaned up painted. If anyone local is interested in the engine, perhaps we can make a deal.
It runs well and is a complete engine minus alternator.Deutz Diesel 1984 Ford Ranger - F3L912 Swap

It was his little baby. He bought it in from the grandson of the original owner. The old fellow never took it off road and it was in amazing condition. I helped my dad restore it in and it has been painted one more time since then. It still has the original oak in the hat channels!
I am planning to use the stock Jeep gauges and add a two gauge panel under the dash for a boost. Keep posting pics! I would love to see that installation and find out the costs involved.

Post: Engine swap Is it possible to swap out the engine in an L for an bigger one say one out of an L ? The procedure usually is simply placing heavier weights on the governor.
However, few people can do that for successfully themselves, and many mechanics might be reluctant to do so for other reasons. However, some stripped down tractor models use the essentially same engines as more expensive models but have lower HP ratings Maybe to steer people into bells 'n whistles' models. Essentially these engines are just de-tuned, but I don't know if governor weights would be the only difference.
The fuel on such engines probably could be turned up, but the engine would run hotter and might need a bigger rad. One of the things a properly designed governor does is to make it hard for any load to over-heat the engine.
Engine swap TOm just for your reference on diesels. Many can be adjusted up on fuel or torque with a screwdriver and small wrench. That is on the older ones, the newer ones will take different shim packeages added or removed from the pump. Some have a good leway of plus horsepower gains, that is in hte bigger farm tractors and some you would be lucky to get 10 horsepower more.
The newer pumps are harder to change and intentionally done to help keep the pollution down from us gear heads. Smoke isn't always power but a lot of people might think it is. Engine swap Tom, your post got me thinking so I checked out Deere's HP rating for itsa 3 cyl Yanmar with 61 ci. Except the is rated at 23gross HP and the at 20 HP. The has So it seems like the same engine is set up to perform differently. Engine swap Here is the difference. The makes its horsepower at a max RPM of or so.
I think the increased engine speed is used to partially compensate for the smaller wheels to keep the ground speeds in high range up to a reasonable figure. I am also learning that running the HST at higher input speeds creates more heat and requires a synthetic or semi- syn oil to deal with the increase. Kubota 's BX also has a fan mounted on the input driveshaft to blow air on the tranny cooling fins. I suspect that Deere may have missed this or some other issue and that is why they announced the and then pulled it off the market to deal with problems that cropped up.
Engine swap Art: thanks for the note. I meant to reply to one of your earlier comments that I think mentioned a vane type of injector pump. I hadn't heard of the design, but as always I'm interested such things.
The mechanism I understood for turning up the fuel is that heavier governor weights don't swing out as far at a given rpm to reduce fuel delivery, so they deliver more fuel per rpm. I guess that the reverse of the idea is that for a given load, a given rpm would be achieved by a lower throttle position.
That idea is from a fairly detailed discussion on another board. I guess there are other ways of affecting fuel delivery as well--or maybe the other discussion was just wacky. The mechanism seems to make sense to me though.
