Response to several comments.
The MG set operates @ 3,550 RPM according to the name plate, which is in excellent condition and easily read.
I see no evidence of an internal pump for cooling, nor is it mentioned in the information I have at my disposal.
The end bells are not water cooled. The only apparent cooling for the MG set is the heat exchanger that surrounds the main body.
Greasing is accomplished by filling cups and tightening fully. Each accepts an ounce of grease. Excess grease is discharged through a short length of pipe, so it does not enter the MG set.
This project will move slowly, as cleaning and scraping the paint and rust is just being done as fill-in. I must spend the bulk of my time working on outside projects, as we have a short dry season here. My goal, right now, is to get it prepared for painting, which I hope to do out of doors so I don't have to erect a temporary paint booth. I have a 6,000 pound lift truck that enables me to move the entire unit outside for painting, which would be far faster than painting it on location. As it has not been wired yet, nothing prevents moving the unit.
Jim, I would be more than interested in anything you can share in the way of cooling this unit. Unfortunately, nothing was included. My well produces only about 6 gallons/minute, so recirculating and cooling will be a requirement. I have a water still, left over from my days of refining precious metals, so I am able to produce distilled water.
I appreciate the interest being shown in this project. I expect I'm going to have to lean on the knowledge of others as I progress, as I am not the least bit familiar with the operation of this type of equipment, although I have seen similar equipment in use.
Wise people talk because they have something to say. Fools talk because they have to say something.
