My Toro 44 Proline has a Kawi 12.5 hp FB460V recoil start. The PTO clutch is specified by Toro to take 2.9 amps at 11.6 volts at 3000 rpm. I assume the Kawi has a 3 amp alternator, but I don't know for sure. The p/n in my Toro manual for the alternator coil is 59031-2065. I have the Kawasaki Workshop Manual on the FB460V, but the electrical info is geared to this motor with an electric starter, and is not much help. I have not bought the engine yet, but am looking to swap the Kawi 12.5hp for an 18hp Kohler single cylinder recoil start that has a 15 amp alternator. The swap looks straightforward mechanicwise, but I am worried that the bigger alternator on the Kohler might cause problems for the PTO clutch (Toro p/n 54-3200, actually an Ogura, I think). Anyone have any advice on this?
