Please take lots of pictures of diesel bikes.  I have a Yanmar 2v78 V-twin I want to put in a motorcycle.  I have some ideas but I'd like to see more ideas before I build.

Oh, I think I saw you on the webcam.  Were you the guy with the leather jacket and the goatee and a belly?

Hi Ronmar,
Are the inputs of the AVR from the output of the main windings (120v) so you can buypass the excitation coils? 

How did you "Here is my ST-5 with harmonic winding disconnected under 1.5KW of load with pure DC being fed as excitation:" as that looks great!

You can expect to be able to produce 3kw from the ST10 head when driving it with the Listeroid 6/1.

That's what I'm planning on.  I was trying to get a 7.5kw gen head because I have a 12hp yanclone and a  20hp 2V78 Yanmar also.  Tom at Central GA Generators (which was super to deal with) was out of 7.5kw at the time and made me a good deal on the 10kw unit.  My 2V78 can handle it if I need it to.  It was all about options for me.  It is way overkill for a 6/1 though.

On the bright side, when running the 6/1 I don't have to worry about any load balancing as I can draw all 3kw from one leg of 120v and still not be overloading that side.

Thanks guys,
Luck of the draw on the balance.  I am amazed at how easily they start (how slow they can be turning) and still kick back to life.  Anyhow, I was just glad that I had some decent parts to work with.  I don't want to speak too soon but it appears to have been a "diamond in the rough."  After some polishing it cleaned up nicely anyhow.

For the last several months I have been reading on the two listeroid forums and notice I'm not alone.  I am an aircraft mechanic and commercial pilot.  I was a professional bush pilot/mechanic but now only fly for pleasure once in a while.  I guess the A&P mechanic in me comes out often and that's probably part of the thoroughness...it's also why it takes me a while to do a project like this as it's not done until it's right!

I appreciate all that I've learned from this group and the other group.  You guys helped me learn about listeroids and other things.  Your knowledge and even heated discussions have been a big help. 

My exhaust lifter spins really well and the intake spins but only about 10% of what the exhaust one does.  Hopefully it will get better with time. 

Now on to learn about co-gen and using WMO, dual fueling with natural gas, etc...

Thanks to all for your help in your prior posts before I even got this thing.

Man, I hate to hear that.  I hope you get things settled there.  It doesn't sound nice.  I don't have the GM90 but I'm familiar with the 6/1 listeroids because I just got mine back together today and ran it for the first time.  I can tell you what I'd do if it were my 6/1 that I am intimately acquainted with.

I don't know your fuel system setup but if water got into your fuel tank I'd remove the injector pump (which has been sealed so no water should be in there yet).  I would do that to keep any contaminated fuel from getting in there.  Then I'd drain the oil out of the crankcase, pull the injector out and turn it over to get the water out of the cylinder.  I'd then use an air nozzle and blow the cylinder out for a bit then squirt a bunch of wd40 in there and on the outside of the injector body to keep it from corrosion.  Then I'd drain the fuel system (tank and lines), put on a new fuel filter/water separator, put the injection system back together after blowing out all the lines etc and bleed it.  Then I'd pour new oil in and run it to get it good and hot.  If the engine oil is milky gray after that run I'd change it again.

If I couldn't run it for a while I'd pull the head, cylinder, piston w/ connecting rod, dry it all off and hose down with wd40.  Don't forget to hose down the crank and bearings with WD.  From what I understand, WD stands for water displacing.  It will keep things from corroding for a little while.

The generator I'm not sure.  I'd try to dry it out before running it and you may need new bearings.  The rectifier may or may not be bad.  Most are pretty robust but they aren't made for soaking. 

The thing is this isn't your only problem you're dealing with, so time isn't too available I'm sure.  If I lived closer I'd offer to come over and help but I'm a long ways away.

I posted this on the listerengineforum but thought there might be interest here too.

Today, 4/29/11, was the big day.  I started up my 6/1 Jkson/Powersolutions.  I have a little oil leak on the pipe that connects to the elbow for the oil pickup screen but other than that everything seems good.  I bought this engine in Feb 2011 from a guy who bought it originally in 2005.  He bought it but never ran it.  He had taken things apart a little here and there.  It was a deal too good to pass up. 

What did I do with it before starting it?  I tore it down completely and removed a fair amount of casting sand from the webs inside the crankcase then bead blasted the piston to remove casting sand from the underside of the piston.  I had to put in new connecting rod bearings due to fod then use plastigage to verify clearances.  I painted both the inside and outside of everything.  I had to make an offset idler bolt and got the lash down to .0045" on the cam gear.  I had to hone down the glazed cylinder due to the sand used in the Indian break in :-).  I put in new sleeve o-rings.  Some of the oil seals were bashed in so I put new ones in when I put in new gaskets for everything. 

Anyhow, I made two videos of it, the first and second starts and I have a lot of photos on listerenginegallery.

I have an ST10 that I will run with the 6/1 and also my 12hp yanclone tractor.

Anyhow, I just wanted to let folks know another one came to life on this fine Spring day.

There are still some gems hidden out there that can still be had.  I had to travel several states away to get it but I was already going near there to go skiing. 

I had an 81' diesel VW Rabbit that ran away on me.  It felt like a V8 was under the hood.  That was the only time I buried the speedo.  The rings were worn and the blowby pushed oil up the breather tube which attached to the intake plenum.  Well, the rest was history.  I was able to use the brakes to get it stopped but it had blown the head gasket.  After that I just had the breather dump overboard.

Belt driven accessories certainly use more fuel than electrical ones. This is why nearly every new car comes with an electric cooling fan these days.

I actually think it's because most cars these days have transverse mounted engines and none have side mounted radiators.

If you go to my listerenginegallery link above you will find my new album with photos of the gen head.

I just got an ST 10 with the rheostat from Tom a couple of weeks ago.  I can't say enough good about working with Tom.  He also supplied me an 8 rib micro-v custom pulley.  Anyhow, I can get some photos of it if you want.  The doghouse is still flimsy as well as the brush guard and fan guard.

The only thing the rheostat does is put resistance in the field excitation ckt to drop the field voltage which in turn drops the output voltage.  It is placed on one side of the DC coming from the rectifier one side of the AC before going to the rectifier.  It's between the rectifier (DC side) and one set of brushes excitation coils and the rectifier.  If it fails, just remove the wires from the rheostat and place the brush wire directly onto the rectifier and it would be a standard ST.  It reminds me of the rheostat in airplanes for dimming the instrument lighting.  

I'm building (rebuilding what the Indians damaged in their test run) a new PS 6/1 listeroid and am making a couple of offset idler bolts.  I hope to run the engine this coming week then start building the base so I can mount the gen head and give it a whirl.  You can see my progress at http://listerenginegallery.com/main.php?g2_itemId=4911

I just went out to the garage and popped off the doghouse cover.  I'll post a few photos into a new album for the genhead.

[I tracked down the wires to the rectifier and made the changes above via strikeout.]
