Engine / Gen end identification help request
« on: Today at 01:41:30 AM »
Good day folks.

I just got the deal of a lifetime, in my mind anyway.

I don't know a ton about Listers but One look at this old girl and hearing previous offered prices. I was happy to double all others and offer $600 for it.... Id guess running it's worth at least 10x that.

It was the backup generator for a good sized farm up until 15 years ago when they upgraded. But was running great then and the engine rolls over. I didn't want to attempt starting until I'd had a chance to go over it and make sure everything is good.

I'm struggling with identification of model and year. None of the engine number decoders I can find seen to make sense of it properly. The plate looks to read: Engine #  2590HR219
25HP 1800 rpm

The plate on the generator says Generator No. 2/54617 and has some bearing sizes and information but no kw rating or anything else.

I'd love to know any specifics, ratings and any other information possible.  Photo links below.

Lister ST2 (might be SR2) with a Brush SCAFF generator head, probably rated at around 7KVA. You will probably need to replace the old selenium rectifiers with modern silicon rectifiers. 1800 RPM indicates 60Hz so most likely a 110 volt output. Would have been built in the 1970s.

Looks to be an HR2. My guess would be in the 12-15kw range.

If it runs and generates I would say $600 is a great deal.

Looks to be 1969 manufacture date. Last two digits plus 50 is how lister did it until the early '1980's
