Hi Ernest,

I would like more solid info on whether the gears are really
robust enough to handle the load.

 


The alternator that is 80% efficient and is pushing 50A requires just about 1Hp.
What I've seen of the gears, unless they're made of pot metal, I don't see how they couldn't be stout enough.  I haven't rebuilt my engine yet, so I'm going off drawings (probably not to scale), and measuring the gear on the CAS.  I think I calculated the torque at considerably less than 10in.lb., but I'd have to find the napkin that I calculated that out on 8*)

PS:  If you are doing 4 things at once you're doing better than me. :)
