On this particular unit there is a pulley on the other end of the crankshaft driving an exciter. From what I understand, though, this was a used unit when installed here in 1931.I believe you will see that is actually a flat belt pulley-yes also a container for the governor weights.Notice the heavy hub attachment. In the case of a generator it could have driven the exciting generator.
Yes, there is linkage, a long rod of some sort.Is there a linkage from there to the fuel system ?. If so it is the governor.
Yes, this is the "Historic Fall River Hydroplant", but it also has this old Fairbanks Morse machine. We're closed after Labor Day. Although this equipment has not operated since the 1982 flood, it's pretty interesting stuff. We have a number of EE volunteers (not me) so we know quite a bit about hydro units. I'd just like to learn more about the old diesel as well.Mike, is this museum in Estes Park? I've been there and never seen it. Looks like an interesting place. I get across the hill to the Denver area once in awhile, might be worth a side trip sometime. . .
