Does anyone have a link or some advice on doing an engine swap on a d6100e?

I have located a d950 I'm supposed to pickup in a few weeks.

I have done many creative engine swaps on cars, boats, trucks, and even recently an 8.1l fuel injected engine with an Allison 5 speed electronic transmission into a 1977 airstream argosy motorhome, BUT I've never done one on a small tractor and was curious if there are any specialty tools I might need or good places to find a workshop manual that might have torque specs. I'd like to have anything I need ready so the tractor isn't down too long.

I know the d950 will basically bolt up minus the upper radiator hose situation being a little different and it having a true alternator instead of the dynamo.

All I can add is that I had a d950 engine in an ancient Steiner tractor that I felt was amazingly powerful for its size. I think you will be very pleased after you have sorted the swap. Good luck.

Upper and lower radiator hoses are smaller, you will have to neck down the radiator end of both.
There is nothing needed specialty tool wise to get it done.
The D950 could have a dynamo or a true alternator.
If you change the oil pan, change the pickup tube too.
You can get the WSM off Kubotabooks.com

I might just purchase another radiator and use normal hoses. Those all aluminum radiators are fairly reasonable. I'm guessing I would just buy a 7200 radiator and it would prob bolt in.

I always remind folks to insert a wooden block on BOTH sides of the bottom of the engine at the front axle. This keeps the engine from flopping to one side or the other when it's unbolted from the transmission. I always block the rear tires and roll the front of the frame forward, but to each his own. It's a simple process.
