Wisconsin TJD

[MichaelBeck]

Looking for a Wisconsin TJD engine for a Ditch Witch J20 trencher. Does anyone know what other equipment might have used a TJD engine with the same crankshaft as the J20 trencher. The current engine has a hole in the block so I need to tear it down to see if the crank is still usable. If so maybe I could possibly find a TJD and swap crankshafts if I had to. Thanks

How about a VG4D? I'm not up on Wisconsin engines, I don't know what interchanges
But I know where there's an engine like I mentioned above

600 series bobcats used that engine along with the john Deere 14t square baler.

Be careful. It's possible that many of these engines were THD'S and not TJD'S. The THD is the odd fire version and the TJD is the even fire. Unfortunately, they are pretty much identical in appearance, so check the nameplate. To use your crankshaft in a THD block would require that you also change cam, flywheel, and ignition. Also, Wisconsin rated THD at 15 hp while the TJD was rated at 18 hp. No idea what, if anything, was done to get the 3 extra ponies. Does your application require a special crankshaft? If no, then why go to the trouble to change it?
BTW, the VG4D is a v-4. Very few parts are interchangeable. Certainly not the crankshaft. One last comment: these remarks are from an 80 year old memory. Verify everything I have said before you act on it.
Good luck.

I'm not up on the Wisconsin's. I never got much chance to work on any. Haven't seen many of them around here over the years

Thanks for the responses. I’m not sure what modifications it would require to install a VG4D since it is a larger engine. Regarding the crankshaft, from what I have read and been told, the crankshaft came in different configurations depending on the application it was being used for. The output shafts are configured different . I need to remove the TJD engine for a closer inspection and do some more research. The current engine has a hole in the block.
