I would need a serial number to verify that in fact you do have a M-610…. if it is…. the 610 came with the VH4D Wisconsin, not the VF4D. There are a number of internal differences for the bobcat VH4D from a baler, concrete saw, etc. VH4D. I would recommend going to the facebook group Melroe Bobcat Owners of America…. a ton of knowledge over there.
I have a 500 that has a Wisconsin tdj 18 hp inline 2 cylinder conversion from the stock kohler. the tdj was used because of the tapered roller bearing on the crank, although it has since been converted to a fixed speed chain drive. So side pressure is not a issue now. But those you might want to look at if the vari-speed trans is still good in yours. But it will be weak turning at being only 18 hp.
