Happy New year everyone. I'm hoping someone with some knowledge or available parts on the shelf to compare can help me determine some interchangeability of crankshafts. I am working on my personal JD Gator with a 16hp Vanguard. (Of course JD won't give you a Briggs model number to offer up) I also have a 21hp Vanguard sitting on the shelf that I'd like to swap in (Model 381447 0xx3-E1 [middle two numbers illegible] 00071011). The first obvious set back is the crankshafts. The Gator shaft is tapered where the 21hp is a standard straight keyed shaft.
This is where I need help. anyone know if the internal specs are the same? ie: stroke, journal diameter and width, etc... I can and plan to open them up to compare before I swap the 16hp into the 21, but was hoping I could get a little light shed before I take it that far.
Thanks
Chad
