Fairbanks Morse Diesel I.D. Help

Re: Fairbanks Morse Diesel I.D. help

That is a Fairbanks Morse Y-V hot head diesel/semi-diesel or oil engine. To start these you have to have the torch going to get the peg in the head red hot so it will have enough heat in the chamber to light the fuel off under the low compression. 14" bore and 17" stroke on those bigger ones like that. What information are you looking to get on this one?

Re: Fairbanks Morse Diesel I.D. help

This machine is in a powerplant museum where I volunteer and I know nothing about these. The first 2 generators at the plant were hydro units. This unit was installed to drive a small generator so that the community could have some minimal amount of electricity during periods of low water flow (middle of winter). My curiosity started when a new volunteer asked my what type of governor it used. I'd like to know when this machine might have been manufactured as I understand it was a used unit when placed in service here in 1930/1931. Is there a place where I can get additional information of any kind about this model? Thanks.

Re: Fairbanks Morse Diesel I.D. help

The original dyno sheet for mine mentions fuel consumption of 3.3 gallons per hour under load.

That is the pulley or shield for the governor weights on the inside. I am not sure what the actual name was for it that Fairbanks used though.

Okay. Between the spokes I see a couple heavy springs and weights - which are part of the governor system I presume?

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.

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. . .

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.

Is there a linkage from there to the fuel system ?. If so it is the governor.
Yes, there is linkage, a long rod of some sort.

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.

In my olds manuals Fairbanks only calls it the governor and does not refer to it as a pulley or anything else but the governor. I know I have seen small water circulation pumps runs from it but that is all.

Regarding this machine, once it is running does the burner at the head stay on to provide heat for combustion? Also, would this burner use the same fuel as the primary fuel to run the engine?

Mike,
Go to Old Tacoma Marine where you can download a complete manual of this engine. The torch is a starting torch to heat the tube and head for 15-20 minutes to start and is then turned off. It is fueled with diesel (back in the day probably a heavier oil) which is the same fuel as the engine uses but from a separate supply and 100# air.

Dave, Thanks for that info. The manual really clarified some things for me and I'm sharing it with a couple other guys out at the museum. Mike

The Central North Dakota Steam Threshers in New Rockford, ND. have a similar Fairbanks only it is a 75 hp twin cylinder. It uses glow plugs instead of torch's.
