Engine Replacement

[AES 1815]

I have a 2007 John Deere with the Yanmar 3TNV76 engine. The engine blew, I am guessing the oil pump went on it. There was plenty of oil in the engine. The tractor only has 276 hours on it. I have been quoted $12,000 by the local JD Dealer to replace the engine. I am thinking of having the engine rebuilt. I will have to pull the engine and get it to the rebuild shop. Looking for a step by step guide on pulling the engine. Does anyone know where I can find one?

I think if you need a step by step instruction manual to remove an engine you should bring it some where. Try a smaller diesel shop and not a dealer.

The OEM JD service manuals are very good, and provide step-by-step instructions. You do need to use common sense and it is good to have some mechanical experience.

I have done the frame-mounted deeres (955), and the non-framed deeres (4300). All the parts were available and not crazy-priced if you are resourceful. For the engine, you may only need bearings, rings, gaskets, and possibly oversize pistons. Labor to bore the cylinders is not expensive.

I do not know the 2305. I have posted some of my rebuild projects on TBN.

I second the OEM JD manual suggestion. They tell you exactly what to do with pictures.

The 2305 motor isn't that difficult to get out as tractor engines go. It has a frame and a drive shaft to the rear hydro. You don't even need splitting stands, just a cherry picker and some jack stands.

So the 2305 sounds like it is built like the 955. That does make it easier, and more like a car than a traditional tractor. The engine is suspended on rubber engine mounts on a full-length frame.

Sorry to hear about a blown engine with so low of hours on it. It' a smart thing to try to reach 500 or more hours on a new machine within the first 5 years. This way, should anything falter, the powertrain warranty kicks in.

Knowing Deere's use of Yanmar engines, it's always good to research if the engine is limited production or as a wide global production. The 3TNV76 is defined as a,
3 = 3 cylinder
T = inline
NV = family generation and tier emission level
76 = piston size.

If you do a search of use for this engine, it's found in these Yanmar tractors,
GC219
GC222
GC223V
GC322
GC322V

With all that said, this engine has a limited use to locate parts outside of any Deere dealer.

The 3TNV76 was never made as a 3TNE76, 3TNC76, 3TNB76, 3TNA76, nor a 3TN76. It has no prior engine family history, making the 3TNV76 engine very rare. Knowing this, I would of passed on a machine with this engine.

IF you look into re-power engines, chances are a 3TNE78 engine could fit on your machine. The Hp would be a tad better. The 3TNE78 is a very popular engine used in many applications. It has a family generation history too, so parts availability would be greater.

If he's asking how to step by step remove it, probably a waste of time. I just took a Cummins out of a Dodge to put rings in it and lap the valves a little. Fella had a chip in it and it broke all the top rings into short pieces. It broke the second ring on one piston and then he had a miss. I never had any kind of book, I just did it, ran good.

A Cummins would be 3X the size of his little 3 cylinder Yanmar engine in the compact John Deere.

Yeah, I know, right.

How did the engine blow? Did it window the block? Lock up? Eat some bearings?

Thanks to everyone for taking time to reply. I will look for the JD OEM manual. I have pulled a few car engines, just did not want to assume a tractor engine would be the same. Be well, be free, be happy.....

The Yanmar engines are used in the ThermoKing and Carrier truck refrigeration units. And yes, they will have different model numbers, but Yanmar does not change the internal parts for different product manufactures.

I worked at ThermoKing plant in MPLS and have some knowledge of how the engines were specified.

If you have a ThermoKing or Carrier dealer near you, you might want to check on their parts prices.

You did say if the block is OK or not.
