WELCOME worm to GT talk, glad you joined us. Is the 320 the same series tractor as the 318 330 332? I'm not familiar with the 320.

According to tractordata.com the 320 was made from 1991-94 and replaced the 285 in the lineup.

Welcome to GTTalk worm.
The only advice I can offer is that the small engine specialists that do re power packages may have a recommendation for you.

yes thats the mower ,and it has the vertical shaft and i found that repower section earlier on sew but i also found the same motor at Surplus Center - 26 HP KAWASAKI LIQUID COOLED ENGINE FD731V-BS07 cheaper with exhaust .i sent them a email today to confirm shipping charges . i was interested in the fd 731v-bs07 for 999.00 but it is not a exact replace and was hoping i could find someone who may have already been there and done that , first off the crank shaft is longer by over an inch , and the wiring connection is the same plug but wired a little different . plus the deminsions are a little larger than my motor which is a fd 590v-as00. of course my motor is a 18 horse and this one is a 26horse, not sure the hood will even fit with the bigger motor . and kawasaki is no help .but any suggestions or ideas or advice greatly appreciatted
thanks

Unless you need the extra HP for mowing or other PTO work I would not go to that large an engine. The transmission will not put that extra power to the ground. You will use a lot more fuel with the larger motor. The thing about a properly done repower kit is that the sellers have done all the research and you have assurance that the hood will fit and all the controls will work etc. Just buying a bare engine, particularly one that is much larger, is not the same deal. A larger engine will require more airflow for cooling, for instance, and at the same time it is larger and there will be less room for airflow. I'm just trying to point out some of the potential downsides to this.

well i really dont need the extra power ,you are right but in a parts search for engine parts i run across sew and they have a section on repowering , and according to them this is the motor kawasaki recommends to replace mine , that what sew says but they also willnot guarantee it will fit ,my motor is obsolete, i can still get parts , and after checking on parts for mine and coming up with a list of parts that add up to between 600 too 700 dollars , and i found this motor for 979 plus shipping with a 2 year warranty and 8 more horses , i just thought if its not to much trouble i would give it a try , and i was kinda hoping someone on here has already done this swap and could give me some guidance , now if you know of anywhere else with some information on repowering a 320 i would appreciatte the info but in my personal search sew is the only one with any info on a 320, of course i know there are probably others but i have not found them yet
thanks

If youre idleing the engine all day the bigger one will use more. But under the same load the fuel usage will be indistinguishable

the 26HP is a power house. My brother has one on his Bad Boy zero turn. Only stalls out when cutting the 4ft fields LOL

well i really dont need the extra hp but when parts are going to be 600 too 700 and i found this fd731v on sew for 999 plus shipping with a two year warrannty, and sew says this is the engine kawasaki says is the replacement to the fd590v-as00,but they will not guarantee the fitmentof the motor or talk of the specifics involved in the install so i thought i would look into it ,and i found this web site and thought as many of these engines that are out there some on here surley has already done the swap, and could give me some advice about what is involved , but since you feel like this is the wrong engine what would you recommend that will bolt up with no hitches.
thanks

It could be that nobody here has any experience with the engine and tractor combo you have. You may have to just go with the best info you can get and solve any issues that come up.

It sounds like your leaning in the direction of a repower with alot of unknowns. The rebuild is cheeper and you know it will all fit under the hood!

yes i am leaning toward a path of the unknown , but i had breakthrough today and i found a gentleman who has done the swap and sent pics , it will work , and the hood will shut , now i need a wiring diagram for my 320 , if any body can direct me to where i might find one , i have looked and searched but not found one yet
thanks
