I think I asked you before but I've unfortunately lost that information, I hope you can help.
I have an '04 and I purchased a '05 generator. My question is about gear matching. The '05 unit has a "B"gear, and the '04 gear has no marking. Can I swap these out?
The '04 by now has 70,000 miles on it so is reasonably well worn in on Rotella Synthetic, if that makes a differnce. There is no sign of malfunction, I am doing this preventative exchange for track reliability.
