The switch I got from bus depot was  068-919-081  oil switch 11187. Since I
told them what it was for, model and what it was doing, I am guessing they
shipped the proper one. They originally sent me the one for air cooled and
had to ship the right one. I dont know if it is an aftermarket or a dealer
item that they are reselling. I thought my problems were cured when I
replaced it.
Thanks,
A J
