Ok I may be wrong.
I pulled the box so i could remove the cover for pic. and noticed the 1 wire taped off.

Just finished Red Koteing the fuel tank, even found a pin hole when scrubbing the inside.

I remember reading its 3 wire.

I looked at the 2 wiring diagrams i got from winpower. 1 is 4 wire marked 125v,L1,L2 and n.
1 is 3 wire  marked L1,L2 and n

I also got a winpower GM308w4a  GE 308w7,  twins to ours  except on a 1800rpm 7.2hp gas engine  3.8kw that are 4 wire.

I haven't studied them but will check closely on that 3 wire.

Gary check your email.

Gary you do make a nice looking engine. I see you have the 25mt starter and need a fan too.
What paint did you use?

I wonder how many original outlet boxes survived?

Millman

My mind has been leaning in that direction, But its been a long long time since i saw the insides. I know the armature is a tapered.  Was yours or did you convert with stub shaft coming off the flywheel?  Or is a ST1 Lister different?
Wouldn't happen to have pics of the process?

I imagined the possible need for a reinforcing plate inside the ST head, Never had my hands on one yet but have seen a pic of the bearing retainer. Truing it does have me worried as i don't have a machine shop handy.

I am about to make a decision on buying a couple 15hp diesel engines to build a gen set with for sale.
7.5 or 10kw ST heads?
F (DIN 70020)            11,4 kW (15,5 HP)
IFN-ISO (DIN 6271)     11,0 kW (15,0 HP)
ICFN-ISO (DIN 6271)     9,9 kW (13,5 HP) @3000

The lowest graph says 11.5 hp @2350rpm but i got to look up those standards

No specs but saw pic of same engine on a factory 120/240 genset @3600rpm?

But i start cleaning up the tank and mounts so i can reinstall, and try to fire up the Lister before the weekend is over.

Decent weather in south Mississippi this weekend.

It was a three month project and it took 2 parts machines to complete ,the ugly machine on the pallet with the gen head is what i started with ,color is Hunter Green,it is a tapered stub shaft shaft off the flywheel and the generator through bolt holds it all together.
Next time(?) i will start with a complete machine. By the way our machines have internal oil lines different from most and allow with the correct bango fittings an external oil filter,i made a workaround and when i got the 2nd parts machine it had the same thing=the workaround! i can post pictures of what i am talking about because in my search for the bango fitting no one knew what i was talking about as it was an option that pretty much was rare.

Yea the Purolator. I would like to examine a spin on set up.
My parts book shows both but its unclear.

Been wondering how to tap in for a oil pressure gauge.
But thinking about a different by pass filter set up.

On yours where the cap is and  with center the bolt removed can be an oil presure hookup
i have added pictures in the gallery,nothing close up but you can get the idea

When a SR1 is equipped with a Delco starter, its a 10mt, like a Hyster fork lift. common car starter size.

The 25mt is a diesel starter common on all small to med 4cyl John Deere diesels and many other,  Over kill on this 6hp engine.

Look at the commutator end on my head, the aluminum fan on the end of the shaft 1/2 of the fan blades are broken off

This is needed for cooling. I didnt notice any on yours.
Its in the parts break down i sent.

I will  try to find/ make something. Don't need the gen head getting hotter than it has to.

   OS.     it sounds as if yours is a single bearing set, the c/shaft extension register and PCDs are identical on standard STs and SRs so one option is to bolt a 2 bearing alt to your SR using a parallel c/shaft extn and a coupling,  the one I repaired was a 2 brg to start with.     If you look on my album there are before and after photos of it.
The front cover was faced up true to the machined back side to enable a 2mm male register to be cut, this locates the alt concentrically to the engine adapter, there did not seem any point in any fancy reinforcing of the inside although I did use some load spreading washers on the 4 bolts.  The AVR controlled Chinese ST head is not a patch on the Brush 4.5 Kva it replaced, for holding voltage or anything else.  SR1 @  3600 rpm? Not long for this life at that speed methinks, ST1s sound grim at 3000.

Mark.

Gary

Ahh I just didn't use a comma.  Wouldn't happen to have 2 fans?
It would be a pain to get geared up to do castings.  And should it be angled?

Millman  I searched for you name and nothing cam up.

Yes the factory winpower head is a 1 bearing.

No specs but saw pic of same engine on a factory 120/240 genset @3600rpm?
This is referring to a 15hp diesel engine i am looking at buying

OS,          search the gallery for PICT0705 and PICT0810, before and after photos of the ST1 set.

Ahaa!  Makes a nice package.

No pics of the insides?  Well the adapter on mine is different anyway.

Interesting muffler, Know what kind it is?
