Which engine is in your Yanmar

It is possible, after the 1.413 there is a japanese letter which I can't totally make out. It might be their symbol for cubicliters.

Looks like Yanmar uses that 3T84 engine a lot. Thats interesting.

Does anyone have any idea which engine is in a JD 750? I've got a new (to me) yanmar 1610D which has a 3T75U engine. I note the JD 850 has a 3T80x engine. Just wondering which JD model is nearest to my 1610 in case this is ever useful to know.

This whole discussion certainly helps relate grey-market to US yanmars, at least with respect to the engines.

The engines in newer JD and yanmar are as different as night and day. Yanmar builds engines to John Deere specifications. The intake and exhaust manifolds are on opposite sides of the head. This is the first difference noticable when comparing the engines. The injector is mounted different and doesn't appear to be the same, I'm not sure on that one. There are componants that will exchange, the starter, alternater, possibly the injector. but the castings for the block and head are completely different. I know that the early yanmar built JD's were the same.

My F22D has a 3TNB82U engine. Rated at 22PS at 2500RPM.

My F16D has a 3T75U-NC. I think it is similar to the 195D US model.

Yep, Chris....Yanmar did use that 3T84 engine in a lot of tractors and other things as well. I see it in a variety of displacements and it sort of reminds me of the Chevy mall block Engine. Basically the same casting, but depending on internal parts that engine ranged from a two barrel 265 cu inch "economiser" on up through the 400 cu inch "mighty mouse" version.

I stopped by the John Deere dealer to see which Yanmar engines were in the different Deeres.
455 - 3TNA72UJ3
650 - 2T80UJ
855 - 3TN75RJ
790 - 3TNE84EJK
990 - 4TNE84EJK
Trail Gator 4x6 - 3TN66C
The JD 735 front mower has a weird V-twin vertical Yanmar diesel but it is packed so tight I couldn't find the plate.
