This is another one I was meaning to post about ages ago. This swap is into a Williams Wildcat skid steer tractor. Pretty cool piece of kit. From factory it ran the Wisconsin V4 - a popular stationary workhorse engine of that era. Not easy to get parts for over here these days… so what’s an alternative?
Throw an EA81 above the location of the old engine with a solid shaft connecting the two hydraulic pumps that are mounted on either side of the engine, directly to its crankshaft.
This one utilises a belt to deliver power from the flywheel to the hydraulic pumps:

And this is the Williams Wildcat: The V4 in place:

Very low centre of gravity gave it an edge on inclines, you can drive one of these across the sides of hills that would be considered dicey at best in a regular tractor. Great for slashing hillsides with.
If anyone happens to be visiting Melbourne in Oz, head over to Spotswood Science works - they have what I think is the last one off the production line in one of their display sheds. Many of them were construction yellow, which is what this last example is painted in.
That’s it for me and creating/swapping Subaru engines into bits of machinery. Now curious if anyone else has any to share, given the lack of responses so far I’m guessing it’s a pretty rare thing to do!
Cheers
