Help me find a drawing (SD7 showing placement of prime mover)

Want to do an SD7 with the side doors open. Like this.

 

I'd say that picture does most of the explaining itself. The prime mover sets directly under the dynamic brake blister and exhaust stacks.

I'm planning on cutting part of the long hood off of an old GP7 and stick a prime mover in it at some point.

 

How about this? EMD SD7

 

Thats a GP-7 but the SD-7 is the same. More space in front of the Generator and more space behind the aircompressor is the only difference. At least on the SD-7 a fat guy could work the rear of the main electrical cabinet. You will find that most if not all EMD roots blown locomotives are laid out about the same.

( I do like the SOO line engine in Candy's pic though. Bet $100.00 I've repaired it at some point).

There's an SD7 operator manual here http://www.rr-fallenflags.org/manual/manual.html. Scroll down to the EMD section.

And... ahem... Candy, that's a GP7.:wink:

 

Thank you so much for the link to the operator's manual. It has exactly what I wanted.

Another question: when changing out the prime mover, was it done through the top?
( sides still on) Seems like it would be the easiest way.

 

I helped change a generator in an SD9 about 4 years back when I was still in the business. We cut the side and top off with a torch and lifted it off in one piece then removed the generator. Ended up retiring the unit instead of fixing it. Anyhow, I would imagine it was be about the same way for prime mover removal. Cut, remove, replace, test, weld and touch up.

 

I've seen generator and engine changes done a few different ways. first of all , If you have a tall crane bay, you can lift off the carbody off the frame in one piece and have lots of working room. If you don't have a tall crane bay you need to remove the handrails and take(cut) the carbody apart, usually I insist on using a sawsall instead of a torch. You can lift the engine or generator just enough to clear the frame and slide it out the side. The generator end is a pain because of the forward radiators so alot of times folks just remove one side and the roof/radiators. GP-40s were a special treat as there is little or no room to manuver the generator.
