Hey thanks, David. I lost my phone a while back and never got to respond. Finally getting back to this project. I'm looking for a manual that has all the tolerances and torque specs to do a rebuild. Or any manuals for that matter. I think anything would be helpful and interesting. Hey, I have a 3YC as well. I got the complete 2YC compressor 1946 model AND a 3YC pump together at an auction some years back. Going to upgrade the 2YC to 5hp and modern starter pressure switch etc. Going to try find a graphic artist to make a new decal as well. I would love to have a remake of the vintage font and graphics from 1946.
Oh boy. Those RPM numbers look interesting. Thanks. I forgot that the pump is going to put a load on the motor and slow it down as the pressure in the tank increases. I can do the basic calculations with no load i.e. a 1725 RPM motor to X RPM on the pump with no load. I'll have to do some research on a load speed but knowing me an educated guess or more like a wild a$$ guess is what I'll end up doing in the end. It will have to have a no load speed higher than 800 because 800 RPM is what it spins with 100 PSI on the pump. Maybe 900 is the target rpm to calculate pully size for no load? I'll see what Google says about that.
Thanks again.
