I have a Troy Bilt Bronco with a Kohler SV 590 19 hp. engine that I have been working on. Last week a friend gave me his Cub Cadet RTZ 42 with a Kohler SV530S 17 hp. engine that blew up on him. I am thinking about swapping the engine from the Troy Bilt to the Cub Cadet and then I will have a zero turn with a newer engine. From what I have found out the only difference I see is that the shafts are a different length. The 19 hp. shaft is 3/32" shorter than the 17 hp.
Does anybody have any experience with this type of swap, any suggestions, or what to look out for.
The only real doubts I have is fitting the pulleys and the PTO to the shaft.

3/32 is not enough to worry about. Just do the swap, and the pulleys will be fine.
Well I made the engine swap this weekend, but came up with one problem. The 19 hp engine came off a gravity feed gas system while the old 17 hp engine had a fuel pump system. Now I'm looking to see if I can just change the tops of the engines out and then have the vacuum fitting and the oil pressure sensor on the new engine. Has anyone had any experience on this kind of swap that they can enlighten me about.
Yes. Everything looks the same except the cover plate on the 19 hp. engine does not have the two holes drilled and tapped for the fittings to screw into. If I could use the cover plate from the 17 hp it would make my life a lot simpler as it already has these in the cover plate.

Yes, it does. Then the 17 also had the oil pressure sensor mounted just above the oil filter on top of the cover where the 19 doesn't have any of this.

Just wanted to let everyone know that the engine swap was a success. Did some modifying on the cover plate from the 17 hp to make it work with the 19hp and have a fuel pump. Also had to replace the governor. all in all I have about $100 in this swap. Since I finished the job I have mown the yard three times with the motor running constantly for about an hour and a half a time. It runs perfectly without a hiccup. And the old Cub Cadet does a very good job of cutting the grass. Thanks for all the help.
