What is behind this generator?

I am going to be buying a pile of parts for my Olds engine and the seller sends this picture of a generator, it has some sort of pump with a reservoir connected to it. Likely from a mid 50's Olds but the seller isn't sure. I've never seen one before, but maybe it's a common part from the 50's. Can you guys help me out?
Thanks

Power steering pump

 

what he said looks like a chrysler product?...

 

Wow, thanks. I thought it might be but my 55 Buick had a p.s. pump with its own bracket and pulley so I wasn't sure.

 

Chrysler? It could be since I've noticed some non-Olds stuff in the pile.

 

The pistons have valve reliefs sort of opposite but not quite.......they appear to be Poly pistons, the lifters also appear to be Poly, the generator is similar to mid 50's mopar, the alternator is early 60's mopar.........dunno about any Olds bits.......andyd

 

Mid 50s GM Stuff had the power steering pump on the back of the generator like that.

 

Mopar generators were Delco also.......

Edit....Autolite not Delco Remy...

 

Maybe some were.....don't recall seeing any. All I remember seeing were Autolite....

 

56 & 57 Chevys also used a Delco p/s pump which was driven directly from the back of the generator, via a splined shaft protruding from the back of the generator.

 

You are right..Brain not functioning...Honey! Bring more Coffee!

 

Mish mash of parts. Mopar alternator Chevrolet starter...generator is not a GM unit...

 

the generator looks to be Autolite-Prestolite, it should have a tag. It is not Delco. The oil pumps are early Olds.

 

Generator/pump looks just like the one that was hanging on my '52 331 hemi.

 

The pump itself is Eaton, same as on a Ford product of that era but with a different front casting.

 

It's a 1956 and 1957 Chrysler power steering unit. Aftermarket part number is a 9115 for the generator. Facel Vega with the Chrysler engines use the generator for their tach drive but two ears are removed for that application.

Thanks again guys. I just wanted to ID the generator and pump, should've cropped the picture better. So much knowledge here.

 

The generator is not smoking so it is not a Lucas.

 

Tommy posted a GM set up - they have a smaller pump - much like some of the later single units...

going with it being Mopar.....and like most have said -it hopefully will still have the tag with the part # on it.....

 

I think if you look at the 56-354 Hemi in my albums you can see that gen. mounted on the motor without the pump, however the drive connection is visible.

 

I am amazed at how smart some of you are. I didnt know what any of those parts were from.

 

Cadillac's had them also.
