Welcome to the forum! I just came across this thread. I have a 108 also, but haven't seen anything on this type of repower. Should be something out there on a similar tractor, as the wide frames were used for many years. Biggest challenge may be in getting a clutch to work for the 3 speed.

I don't know how big a hurry your in but I plan to do this very conversion on a 149 this winter. I have two Yanmar diesel engines out of Tri-Pacs that are rated at 11.4hp. Earlier I posted that they were 8.5hp but I was mixing the KW and HP. I have not done this particular conversion before so I'm looking forward to it.

:welcometogttalk: Good luck with your project.

Chris, yours will be a bit easier, due to the 149's hydro.

This is true. I did do a conversion on a tractor that was not a hydro and found there to be very little difference as long as it is
shaft driven to the transmission.

Hi Jessy:
I'll try and take photos as the project proceeds. You will have to let me know if there is something that you would like more photos of in case I miss something. The engine will be going into the tractor pictured in my avatar. (sp?)

About the biggest concern is adapting the clutch plate to the new engine and having it in the right place.

The adapting should be pretty easy. You will just have to look up parts for a 782d to give you the correct adapter to bolt up to the front pulley. Also keep in mind that because of the rotation of the motor. It will be mounted in the chassis backwards from what you are used to. The flywheel will be towards the front of the tractor.

You guys need to contact Dave Chester over on www.cubcadetcollectors.com/forum He has a 149 with a two cylinder kubota engine in it. Did the conversion two or three years ago I beileve. I have seen it at several plowdays since and it is a VERY well done unit.

Takes all the fun out of it if you copy someone else's work. Would like to see photos of it though and should be a good reference for someone who has never done a diesel conversion before.

One of the slickest CUB conversions I have seen was at a tractor show in Ankeny Iowa.
Guy had taken a cub and stretched the frame and set a Crosley motor and transmiittion ahead of the transaxle.
I think thats the same trannny used in the power kings and that little croosley purred liike a kitten.
