Don't know if this has been mentioned before. I just ran across it today. I didn't know he cared! ;-)

So I'm about at the point where I'm starting to think about generator pulleys.  I've got an ST7.5 in hand, and the engine is slowly going back together.  I can get an ~11" pulley and run the engine at ca. 850 rpm and make the full 8 hp, or I can go for lower fuel consumption and greater longevity at reduced power by getting an 8.5" pulley and running at 650 rpm.  I don't foresee this setup being my primary power source, but I may someday put it supplemental service.  Until then, it'll be emergency use.

My mail loads (in addition to the normal lighting, refrigeration, et al) will be well pump (not submerged), septic pump, and in winter, perhaps furnace fan (propane furnace, but I also have a woodstove that gets used a lot in winter).

Because I'm thinking emergency use, I'm not concerned about trying to pull the electric water heater, oven, or dryer, nor am I thinking of running big tools, the air compressor, etc.

The rating on the septic pump is unknown.  The well pump states: "3/4 hp, 0.55kW, 115/230V, 12.4/6.2A".  It's wired for "115V" so I'll probably set up the ST for 120V only (no 240V).  I don't know the power factor or startup current needs, but there's 1.4kW right there.  Granted, it only runs a few minutes at a time.....

Anyone care to comment?  Ya think 650 rpm will be enough?

Cheers!

I've been tearing down & inspecting my 8/1 and have found some interesting things.  There was a lot of side wear on the piston and cylinder, showing that the piston was not square to the bore.  I'm still taking measurements to figure out why that was.  Also, this engine has seen a *lot* more time than the few tens of minutes or so that I assumed the assemblers would run it to make sure it wouldn't hand-grenade before shipping.  There's a noticeable ridge in the cylinder.  I was bummed.

So, I called Gary at Diesel Electric Service, from whom I bought it.  He said that that was unacceptable; I paid for a new engine and that's what I should have, and that I should make a list of what I needed and he'd make it right.  So for Christmas I got a big box o' parts!  New piston with gudgeon & rings, cylinder block, gudgeon bush, valve guides, rod bearing -- everything that was worn!

Here's a big "Thanks!" to Gary and a sincere endorsement!
