I picked up a 1985 kohler 7.5r62 gen set last year. I'm finally getting time to mess with it. It has 158 hours on it. I hooked it up to a propane tank and it fired right up. This thing runs like a wrist watch. So for good measure I pulled the radiator sent it out to be cleaned and pressure tested. I'm going to change the belt and all the hoses. I also would like to change the thermostat. I can only find a 44 mm tstat in 160 or 180 degree temp. Stock that came out was 170. I'm thinking go with the 180*. Im planning to but this unit in a gen box and use it as a standby unit with an auto transfer switch. Any help or suggestions about this unit would be great. Pics to come!
