Save yourself the aggravation and grief.  Buy a 2 bearing head if that's  what you need.

Things I want to Buy / Re: 7-10kw gen head U.S.

I have 3 st heads and 1 stamford clone.

The first 2 st heads have been reliable units with the standard
windings that are stable under any load. They were purchased years
ago. They will handle an unbalance load without problem.

The third st is a different story. It came with the AVR and digital
output meter. It will run a 120 OR 240 load but will not tolerate an
unbalanced load at all. It will scream  like a banshee and voltage will
fall off quickly with an unbalanced load.

I tried removing the AVR with results as Bruce mentioned, voltage in the
375 range or better.

I would NOT recommend the st head....I would if I could see it in action
with a meter and load in hand, in person.

The stamford clone is a very good, stable out of the box, unit that
I would recommend. Just hook it up and put it to work. No bearings
to repack or replace. No brushes to setup/adjust/clean. No worry about it
being anything more than a boat anchor like my last st.

I am looking at buying another head in the near future. There is no
 other choice at the moment but the stamford clone.


Another item I have with my 1115 setup is a direct coupling from engine
to gen head. It was purchased years ago and I haven't seen one like it
for 8 or 10 years.
If I were to build another 1115 with direct coupling I would use a Lovejoy
coupler and a shop built engine stub. I did this on my last build and am
pleased with the results.

Using belts will work, and I have several belt driven units, but the direct coupling
method for the 1115 series engines is a far superior choice in my opinion.

Listeroid Engines / Ashwamegh 25/2 : we are CLOSE now !

Today I had the opportunity to spend time with the beast.

Checked mufflers and intaked....no obstructions.....I did finally add
oil to the oil bath air cleaner. Remember those ?

Check injectors...looks like the correct numbers to
me ??

Adjust valves....I tried a few methods but wasn't happy...it started
and ran fine but I didn't think the intake had enough play so I did
the old slap and tickle at about 10k straight across.  Starts/runs
fine.
Check load for numbers.....yep, 4.2+ kw..... I am using space heaters and heat guns...checked each one and got the total.

Play with springs...The final spring wiil just hint at wanting to
hunt.....I can observe the slightest movent in the linkage but I
don't really hear a change in engine rpm.


But here are the numbers....

61.5 HZ no load
60.00 with the 4.3 kw load I run.

That is better than it's ever been....
man, I'm HAPPY with that !

I will need to do some more/better electrical work
before I try any heavier load testing.

I know everyone has been on the edge of your chairs with
anticipation, so I decided to spread the joy !

Butch,
When I load it up and am setting outside your shop door will that be close enough ??

I didn't get to it today but you guys have provided a list of.things to look at tomorrow.

I will report back tomorrow evening, thanks for all the pointers.

Before the cam went out for a rebuild I tried 8 or 10 springs, combinations of springs, springs with
bailing wire tied to a fixed spot, springs wih springs......you name it. I got it to just begin to hunt then
would adjust, add, subtract, cuss and holler.......I went back to the original spring....no help.

This time around I have only tried the factory spring. I hope I can get some run time in the next couple of days
after all, I still have all those springs in a box just looking for something to do !

The engine starts/runs so nice I'm pretty disappointed it won't pull much of a load. I have never had much
faith in the thing only because it is what it is. Getting it to run as well as it does has been a joy.
It fires right up and is fairly well balance. I was concerned about bringing the rpms up from 750 to 850
but I do believe it is just as well behaved if not better. Seems to be a bit better balanced and it just sounds
alot better.....hard to describe ....the best description I could give be would be like when a wild cam just starts
to settle in at the lower end of its rpm range.....the lope is gone but no where near top end.

Still hope to load up that Stamford clone head to see what it will do ! The thing just laughs at 4kw.

Enjoy !

I have been using the stock intake manifold with the stock filter setup with stock exhaust mufflers.

With that said, yes I can gently rest a finger on the rack and the engine will  come up to speed.

I haven't had the chance to try differnt springs yet but that will be on the list for tomorrow.


Again, the engine starts right up, runs with no smoke and the exhaust and head temps are within 5 degrees
of each other. No binding in the linkages anywhere.

I thought by going from 750 rpms to 850 would solve the problem, but still no luck.

Today's saga.....

Had some key stock handy so a small task completed.

This engine starts and runs so nice. The temps are so close while running under load.

So here is what we got:

Engine no load is 856 rpms turning the gen at 1850. So my numbers were pretty close.

Engine loaded at 36 amps is 820 rpms engine and 1750 .

Hz is 61.4 no load with 58.3 hz with a 4.3 KW load.


It is better but no where I think it should be. I'm thinking it should pull 7 to 10 kw .....thoughts ??


I will add that startup was one of the easiest so far. I installed the pulley adjusted the slide for the gen
and set belt tension and on start and running I didn't have to touch it ! The usual method is starting and
stepping numerous time to get the belts to track correctly.

I installed.the factory spring and on startup I had to turn the thumb screw a couple of turns to dial it in.

Easiest startup yet  First spin, no problems......

I will begin the process of different springs again and see if I can get the thing to pull a load. It is better but
still no where near to my expectations.....

Enjoy !

Update......after thinking about this for a while I dug throught my
junk and came up with a new 2B pulley and center.

The shaft size was larger so I turned a sleeve for it.

The new pulley is about 1" larger in diameter so if my numbers
are correct it should bring the engine up around 830 rpm or so
from the current 720 or there about.

If I gather the strength tomorrow I'll fire it up and see if it will bring the govenor in line where it will pull a load.

Enjoy !

I think they are called "common back" belts.....

I am runing a new "b belt" pulley on the gen head and running the belts on the flywheel face.
I questioned this method but I see several done in this fashion with success.

I played with it a little yesterday and after a belt adjustment and playing with 2 springs on the
gov I get about a 2.5 hz loss between 0 load and 5kw.  I would like to get it closer and will play
with it more in the future.

I adjusted the valves on the engine per Butch's method and it does seem to run a little better ?



In answer to the other question : The picture is from the coolong side....intake and exhaust are stock.

As some of you know I have had a problem with the engine pulling a load.
Anything over about 1kw and it would just fall flat.
After playing with about a dozen springs and sending the cam to Butch for
a rebuild with new weights and a new lobe I still could not get it to work.

When I got the "new" cam installed I, of course, set the valves but not the injection
timing. Today I set the timing (it was off a few degrees) and re adjusted the valves.
I saw a slight difference in exhaust temps so I did a fine adjustment on the linkage
and got the exhaust temps nearly perfect.

Off to pull a load.....no help......

I have often had the seals on the crank at the bearing housings squeel a little. I put a drop
of oil on them and that will stop. I believe it is because I run the crankcase vent to the intake
manifold instead of the "spring valve" the engine is shipped with.

Any way.....I noticed a very slight squeel while running. Ever so slight......
When running I watch my "kill a watt" and don't check rpms......

Today during testing I installed 1 of the 2 belts I run on this machine....

I thought I should install the other belt to see if the noise would go away......
Well, well, well......the slight noise did go away......
The engine will now pull a 5kw load with about a 1.2hz drop from no load to loaded.

I know the cam change was not a mistake because when I ran it before I always ran 2 belts.

So it looks like I am getting very close. After I got the belts on I took off the 3 springs I had on the
govenor and installed just 1. It is close but not as good as with the cobbled 3 springs in place
so it will take a little more work in that area.

I had to stop today because it is starting to rain and I run it outside but I know I am getting close !

Thanks for everyone's input. I couldn't ask for a more knowledgeable bunch of guys !!

Butch,
I saw that as well. Shoot, at that price I should buy 2 !

Look at the pic with the shadow......looks like the man to me .
