I currently have a John Deere Quiktrak that is getting a little worn in the engine department. I've considered just replacing the engine but the problem is that the exact number is FX691V-ES16. I can't find that engine anywhere. I can't even find the exact specs on it as far as crankshaft length, diameter, etc.

Can anyone point me in the right direction for a replacement for this engine?

A dial caliper. You have a john deere and they don't make life easy for you to bypass the dealer.

If you dont have access to a caliper as @unknownfl suggested, call Kawasaki, they will provide the info you are looking for (616) 949-6500

 

Kawi can get you all that info, they can also tell you what JD does different, typically it has to do with the wiring that makes it "jd specific".

 

i could be wrong, but this might be the one you're looking for.. call em and find out more..
