Warner & Swasey Duplex Division Generator

Hello,
I am hoping someone, somewhere can help me. I purchased a very large generator or some may say a engine generator electric plant. It was built by Warner and Swasey Duplex Division, in Lansing Mich. What I need are some manuals on how to run, maintain and fix this thing, there are some peices missing inside the box. Someone somewhere has this information or knows where to get it.. This thing is huge, Red in color, built in the late 50's like around 1958 and it was put in service in 1960's and provided backup power for the Hutchinson, Kansas airport. I think mainly for the runway lights and the control tower. The engine was built by Continental Motors, it runs.. the Generator was built by EM (electric machinery co.) they are still in business and faxed me the inner workings of the generator and wire schems. I think the Gen. works. The entire unit was put together by Warner and Swasey. for the FAA in 1958 or so.
I do have many photos if someone thinks they have an idea, or knows someone, I can email these to you or something.

There were 250 some of these made and I have the 108th one made in 1958.

Some details are as follows:
120/208
KVA 37.5 KW 30
3 phase 60 Hz
Order number on the plate on front is 8-3425-1
serial is 30-615-59

It was made for the Department of Commerce civil aeronautics administration.

Please can someone somewhere help?

I have one of these huge red 'engine generator plants',too.
I have a direction book and all kinds of other stuff. My engine runs (propane)but when a load is applied, the governor does not adjust the RPM. I don't have it wired to my house yet. I have a person thinking about buying it and I am researching it on the net and found your question.
If I can be of help, I will try.
Please reply by email. Mine is contract number-FA-520; serial number 15-378-60. The FAA took delivery on 9/14/1960

I also have one of these and use it for backup power on our farm in Eastern Ohio. We used to milk cows but now have been raising White Park Beef cattle. We don't need the backup power so often now, but would really like to keep it available, especially with the news of the storms in Florida which will eventually come to Ohio.

It is a 25kva single phase. I have the electrical diagram but not the manual.

This unit actually starts and runs and provides power to our farm. The Continental engine is huge but runs well.

The only problem I have is that it needs 3 8 volt batteries, which are hard to find and expensive. They need to be replaced about every 5 years, which is about as often as we need to use it.

I'd like to change it to use 12 volt batteries which are a lot easier to purchase. It also has a spot for a crank on the front of the engine, but I don't have anything that could turn it over. Possibly I could start it with one of our diesel tractors, but there is no simple way to connect a pto.

Does anyone have any experience with these huge motor generators? I'd love to hear from you.

Hi my name is Misty. My father bought a big generator from Warner and Swazey from the duplex division and he has been looking foe a manual for quite a while. He saw your post and I wanted to see if you were still available to possibly be able to send me a copy of the manual. If so i would really appreciate. My email is [email protected]. Have a good day. Thank you

You might look into changing the charging system to 12v along with any other low voltage engine type electrical. That 8v starter will have no problem on 12v. I've ran 6v starters on 12v successfully.

More than likely the starter is 24v,so IMHO you will need another starter for 12V ,if you change to 12v......a 12v alternator from a car parts shop is around $100,a 24 V alternator is typically twice that ,say $200...

Hello,
I am hoping someone, somewhere can help me. I purchased a very large generator or some may say a engine generator electric plant. It was built by Warner and Swasey Duplex Division, in Lansing Mich. What I need are some manuals on how to run, maintain and fix this thing, there are some peices missing inside the box. Someone somewhere has this information or knows where to get it.. This thing is huge, Red in color, built in the late 50's like around 1958 and it was put in service in 1960's and provided backup power for the Hutchinson, Kansas airport. I think mainly for the runway lights and the control tower. The engine was built by Continental Motors, it runs.. the Generator was built by EM (electric machinery co.) they are still in business and faxed me the inner workings of the generator and wire schems. I think the Gen. works. The entire unit was put together by Warner and Swasey. for the FAA in 1958 or so.
I do have many photos if someone thinks they have an idea, or knows someone, I can email these to you or something.

There were 250 some of these made and I have the 108th one made in 1958.

Some details are as follows:
120/208
KVA 37.5 KW 30
3 phase 60 Hz
Order number on the plate on front is 8-3425-1
serial is 30-615-59

It was made for the Department of Commerce civil aeronautics administration.

Please can someone somewhere help?

Hi, I believe I can be of help as I am very familiar with these generators. if you still need help this post is quite old I realize that.

Do yu still need help with your generator?

It will run just fine on 3 12 volt batteries. I maintain one at a gas station since 1998. I started out by having a custom made 32-volt battery but for the last 12 months I have been using 3 12 volt truck batteries and it all runs great on 36 volts. I mean the relays and the starter motor and everything. I converted it to 12-volt ignition a number of years ago and have to use a 12-volt starting and lighting battery with a battery charger. That was supposed to be temporary while I found a 36 to 12 volt converter.But haven't as yet.

My email is [email protected] my phone # is 435 632-6068 Peter

Yes, I have experience with one of these Warner Swasey generators I have running 37.5 KW OHV one. Give me a call at 435 632-6068

3 x 8 volt batteries is 24 vac.

If connected in series then a pair of 8D batteries will be fine.

Many earlier heavy power engines as well as many large trucks back then and busses still use 24 volt engine starters.

Verify batteries are series and if so then do as above.

8 volt batteries still available for some golf carts maybe but not likely your engine is 8 volt anything.
