Are there any 4 cylinder Wisconsin engine fans on here. I have a 30hp Vh4d serial 5088621. I'm trying to figure out what year it was built. I have searched the net but only found that the 3rd and 4th digit determine the year. I'm wondering if it is possible that this motor is a 1988? The article also stated that early years only use the 3rd number. How do they put it in a certain decade. Is it by the 1st number? The reason I need a year is because they used 2 different oil filter types in these. TIA
Hey guys @Brufab called. Ok I have seen that method used before but it's a catch 22 I've seen some with a serial like that and then on another tag it will have like NOV 66 or something to that effect. But not all hope Is lost. You can call continental engines here is their phone number 800-922-5632 the used to have a couple guys that were very good at establishing that information. At least they did when I was working on the S14D that I was working on. If that comes up empty I'll keep looking on here for what goes on and I'll look more if needed. Have a blessed evening everyone.
