JD 414 engine

I know about nothing John Deere, so go easy on me. I have this power unit came off a chipper I was told. 6414 tf. I'd quess 6 cyl, 414 ci, T for turbo. Whats the F? How much hp will it be? An industrial unit or tractor also? Or can be made to fit a tractor? Not looking to sell. Just would like to know what I have.

We have one on a portable irrigation pump 125 hp i believe that has a turbo on it...also have one on a lagoon pump naturally aspirated 100 hp

Chuck has the HP right on but my book gives variables at different rpms and industrial or gensets. Also my book lists a D or T but no F. Only ever seen one in the older motorgraders, and seen only the 359 listed in tractors no 414.

The 414 was used in tractors. Too many to list. Might have started with the 7000 series in the early 90s. I know our 7410 had one.

I'd like to add they were used in combines too.

If it is written on the plate as a 6414, in theory you have the older block design (round belly). The northern hemisphere tractors never had it. I would not swear that some Chamberlain or Argentinian Deere had it tough. I just don't know.
Tractors starting with the 6000-7000 use the newer 4045 and 6068 (exactly same displacement), that has the new "square" deep-ribbed block, and is still in production.

It appears the 414 was utilized in the following industrial models. What's your engine block casting#?

The earliest built tractor in the United States I know of to use the 414 was the 7600 Deere tractor introduced, I think, in the early 1990's. I do not recall if the last of the 9400 combines may have also had this engine, or if it came with the introduction of the 9410. In both applications of the tractor and the combine, I think this engine was referred to as a 6.8 liter engine and NOT a 414. If I recall, this engine is a longer stroke version of the 359 diesel engine, but based on the same engine block and family. If I am incorrect, please someone correct me. I had never seen or heard of the 414 until I saw the very first one on an irrigation pump several years ago. I am going to go through my best recollection, but I think the 4 cylinder 219 cubic inch diesel engine shares the same bore and stroke as the 6 cylinder 329 cubic diesel engine. The next evolution to those engines was the 4 cylinder 239 cubic inch diesel engine sharing the same bore and stroke as the 6 cylinder 359 cubic inch diesel. The other variant was the 4 cylinder 276 cubic inch diesel, which shares its bore and stroke to the 6 cylinder 414 cubic inch engine. This last remark is something intriguing to me. I believe the 2630 and 2640 Deere tractors from the 1970's utilized the 276 cubic inch diesel engine, while subsequent models went with the 239 cubic inch diesel. Again, I am not aware of a tractor utilizing the 414 in the United States until the 7600 tractor came out. Today, the current version of the 276 is the 4.5 liter, just like the current version of the 414 is the 6.8 liter. The 4.5 liter (276 cubic inch) made its comeback to tractors, at least here in the States, with the introduction of the 6000 series tractors in the 1990's, about 20 years after they originally were placed into the 2630/2640 tractors.

The 414 is a 6.8 litre engine. It is a slightly larger (bored out) version of the 404. Think 4020, 4430 turbo version and later 6600,7700combine models. One of the most widely used engines from Deere. It is capable of upwards of 300 hp, used in models such as 9570 combine and SP sprayers. It is in no way similar to the 359.

Your confused on that thought jdjim,, they are in the same family as the 359,,and nothing like the old 404/466...they have a cross flow head..

Thanks for the comment, Tim. I had forgotten about the cross flow head. I decided to look things up on the engines for my own benefit on bore and stroke.

4-219 & 6-329: 4.02 Bore x 4.33 Stroke
4-239 & 6-359: 4.19 Bore x 4.33 Stroke
4-276 & 6-414: 4.19 Bore x 5.00 Stroke

6-380: 4.125 Bore x 4.75 Stroke
6-404: 4.25 Bore x 4.75 Stroke
6-466: 4.56 Bore x 4.75 Stroke
8.1 L: 4.56 Bore x 5.06 Stroke
9.0 L: 4.661 Bore x 5.354 Stroke

Same family? A 6.8 litre is slightly larger bore 404 w cross flow head. The 359 was made in same era as 404, ok. The 6.8 is derived from 404 and not 359 is what I was saying. I have always been under assumption that the 414 block (6.8 L) was derived from the 404 block.

Looks like I stirred up some controversy? Be Sunday before I can get back to it, but I'll post some pics and someone asked for casting #. Thanks for the response.

The 414 is not derived from the 404 ...the 404 went to a 466 ci. They are designated as a 6.8 liter now . we have a 6.8 in a 7600 and my brother has a 6.8 in his 7630.

Ditto 414 isn't in same engine family as a 404. Below is a list of equipment that utilizes same engine block as 7600

No controversy, I guess I am misinformed. I am no mechanic, nor do I play one on tv...I was always under the assumption that the 404 evolved into the 6.8 414. Learn something every day.

Your okay,, some of this can get confusing,,, the 404 evolved into the 466..

Sorry, you are wrong on this one. The 414 is a 300 series Dubuque built engine. The 404 is a Waterloo built 400 series engine. No commonality other than the green paint and parent manufacture. Totally two different cats. The 6.8 is the kick off from the 414. Just to clear the ar. No offense intended. DW

Here's a couple pics

Yes, that is the "Family" of engines I was referring to,,a group of engines with the same features and design,,this "300 series" design was started back in 1964 with the 1020/2020 3 and 4 cylinder, they had a cross flow head design, which was good, but the 4 cylinder versions had a balance shaft system that was not so good. They had interchangeable rear block cover/extension that allowed for different applications. The 2630 had a beefed up version with 276CID and would interchange with the smaller units "if" you wanted to,,then the 6 cylinder version came along with 329,359 and 414 cid.,,they also would/could interchange with the smaller units...Deere used this Family of engines in most of their industrial units and also was used in small to mid size as power units.

Horse feathers. The 300 series 359 & 414 are the Dubuque/Mannheim/Saran engines with the starter on the right side of the block. The 400 series 404/466 are Waterloo engines with the starter on the left side of the block.
The 300 series engines were very popular in the industrial division, stationary power plants/pumps/marine propulsion and utility tractors.
