Here are the fuel filter pics

Progress update:

I did get a shop to quote me the custom disk and machine a spacer to go on the end of the alternator.  So I will buy a SAE flanged alternator.  I'll throw away the supplied SAE 10 disk and have the supplied spacer machined.  Total cost around $200.  I'll post pictures when the parts show up, they are on order.  2 weeks lead time. 

On the fuel system, I did purchase the EMI3000 fuel filter kit.  It was around $70 bucks.  It is exactly as advertised.  It has a couple of return paths to allow fuel from the dirty side of the filter make it's way back to the tank.  It also will automatically purge air with the same feature.  One requirement is that it MUST be located on the pressure side of the fuel pump.  The kit comes with a bunch of fittings and some plastic tubing to hook it up.  I'll post pics of the critter.  The kit part number is 10-325.  It can be purchased from resellers of TK dealers. 

On the engine controller.  I will probably settle for the Dynagen.  The TG350 series seems to be reasonable.  Just looking for basic control and shutdown features.  Probably going to use it to also run an electric cooling fan. 

Speed control.  I don't know yet.  Anybody have suggestions?
Cooling.  Anybody have leads on good low cost radiators, heat exchangers?  I'll look in those sections of the forum for ideas also.

Progress update:
I found a shop to punch out a 'special' coupling disk.  It's like the standard SAE coupling disk except it will have clearance holes for the 8 dowel pins that used to drive the TK compressor, use the 6 threaded holes on the outermost surface of the flywheel, use the two key pins on that surface for alignment, and match the alternator shaft.  They will also supply the necessary spacer to meet up with the alternator shaft.  The isuzu engine has a 1.75" back set.  I haven't got a quote yet, but they assured me it's cheaper than machining two spacers, one for the flywheel and one for the housing.  When is all done, it will be like an SAE disk arrangement and should be fairly low cost.   

So onto the fuel system on these engines.  Does anyone know about the EMI300 fuel filter system?  TK says it allows 3000 hour service intervals.  From what I understand the old spin on filter system used a primary and secondary.  The manual makes reference about a bleed orifice that allows clean fuel flow back to the tank but indicates it is after the fuel is filtered, so on the clean side of the filter.  I also notice that the old box filter diagram has several lines going back to the tank, not just from the injection pump. 
Then as I read about the EMI3000 fuel filter, it looks like it is one (no pri and sec) filter that has a special path that allows the dirt and water that accumulates on the dirty side of the filter to be returned back to the tank!  That's pretty clever if it is true.  It's like having the drain port slightly opened and returning back to the tank.  The literature says it eliminates failures while on the road. 
Can anyone confirm this?  Any TK mechanics out there?

Update:
I got a quote from a coupling manufacturer.
He can make an adaptor for the flywheel to make it an SAE7-1/2 flange and then adapt the SAE 6 housing up to SAE5.  This puts the pair into a common single bearing alternator from many vendors.  The SAE6 housing isn't very common from what I have found on line.
Does around $440 for the pair of part sound reasonable?  It makes the coupling to the anternator very simple.  I see  one other method in the post for around $300. It isn't a bad route but more parts involved.

It looks like the old kohler has a wisconsin V4 engine.  I am pretty sure you can find parts on ebay for it, but those engines were supposed to be very tuff.  I don't know much about the generator end.  I have an old Kohler 6.5RMY.  I have done nothing to it since 2000 when it was installed.  I bought it used.  There are also some old tractor websites that would help you with engine parts. 
Good luck with the old gems.  Sometimes new isn't always better.

and here are the flywheel pics.

I finally have some pictures of the business end of the Isuzu refer engine.  Even though these engines are D201, or 2.2L DI engines I really think they are the 'SE' engine.  I bought an old book (1985) on ebay and the details (fuel pump and flywheel) really match the 'SE' specs. 
Now for some pictures.  Any ideas on adapting a single bearing alternator.  The housing is SAE6.  I am thinking an adaptor can be fabricated to go into the pocket of the flywheel (after pushing out the pins and threading the holes) to adapt to an sae 6-1/2 flange.  The adaptor needs to take up over an inch of space because the flange to housing spec is 1.19 inch (30mm).  Am I on track here or forgetting some detail?

There are also Yanmar 4TNE-86 engines. They are also known as TK-486 engines. They look very similar to the Isuzu but have an inline injection pump. 
Would that be easier to get a proper SAE flywheel? 
For now I would really like to use a single bearing alternator with direct couple, but  if no affordable options exist I'll opt for a coupler of sorts.

are you making wood pellets?  That engine will run a very large hammermill.

Has anyone figured out how to hook up to these engines?  There are many on ebay from a little over $1000 and as low as $600.  All of them have the pins sticking out of the flywheel for mounting the ac compressor.  They have an SAE housing but how to use the flywheel.  It there anyone who has worked on these and know how to hook up a single bearing alternator to them? I am considering picking up one even though it is much larger than I need because the price is good.  They have very large sumps (15L) and can go 3K hours on service intervals.  That's over a years worth of 8 hour days.  Rebuild parts are really cheap also. 
Anyone out there have experience with these beasts.  I think they are also know as D201 engines. 
Can one just buy a SAE flywheel for these motors?  Anybody have information? 
Several members have started projects with these engines but I don't see any complete.

I would be interested in one also.  I won't be running a lister but I do have an arrowboard engine with deep sump.  Got lots of biodiesel to feed it.
