Today I drilled and slotted the generator slide.
Mounted and aligned the pulley.
Did a few test starts to check rpms and belt track.

Looks like she will be turning just over 700 rpms with the
belt/pulley set up I currently have.

After spinning that monster up 5 or 6 times I am worn out.

Stay tuned, I will get the power side up and running next week end.
I can, at that time, get some voltage and load test numbers.

Enjoy !

After the failure of the 7.5 kw ST head I purchased
this Stamford "clone".

Will post results in the next few weeks.

Stay tuned !
Gary

I received the 230 avr from Tom.... here are my new numbers :

no load
237 volts....118.7 each leg


10 amp load on both legs
238 volts
109.7 on 1 leg
135 on the other

10 amp load on 1 leg
124 on 1 leg
116 on the other

The growl is much worse with an unbalanced load.
If I wanted to use it for a dedicated 230 or 115 gen set it would
probibly be fine. To use it for a 230/115 load it looks to be too much
of a spread for anything with a "sensitive" load.

I plan to call Tom again on monday to see what he has to say.

This only reinforces my decision to purchase the "stamford clone" next.

Again, I will post results.

Thanks for your time,
Gary

My 6-1 runs with a Honda radiator, thermostaticly controlled fan and the orginal water pump
that I rebuilt with new bearings and seals. Works great with no problems.

My question is about the 25-2 that I have. I have run it with a 30 gal galvanised trash can that I put
fittings on to adapt hoses to. I has no water pump so it is thermo cooled. Works fine.

I would like to make it more compact and would like to add a Honda radiator with temp controlled
fan as on the 6-1.  I do have a t stat on the engine cooling manifold.

Do you guys think the coolant will thermo cycle with no water pump ?

Thanks for your time,
Gary

After a few bouts with storms and running a genset for quite a few hours I am considering a
brushless head.
Being "electrically challenged"  I only know I am tired of tje flickering lights. Not to say my system is
terrible, because it's not, but from what I have read the brushless heads are the way to go.

Any input ?

Gary

A friend bought a changfa 1125 and a 15kw st head about the same time
I purchased mine. At that time a Chinese coupling was available that bolted
directly the head and engine that we also got.

He brought his to my shop and we built a nice heavy frame with rollers and he took
it home where it has sat for the last 10 years or so.

Well the hurricane came through. I never lost power but he did.
SOOOOO , today he calls.......think we can get his genset running ?
I have told him for years to get it out and run it, but you know always too busy.

I ride over to his place, drag it out. A trip to his shop for a few feet of wire
and some connectors......presto, bango....30 minutes later......ah, A /C, refrigerator,
lights...all is good....

Amazing, after setting for 10 years it fired right up and runs like a champ !
We set voltage/hz with the kill o watt, I hung for an hour or so making sure
he understood start/stop and what to look out for.

I have always said I hate the noise and banging and clanging of those Changfa
engines but they always seem to run every time they are needed. I probably have
a few hundred hours on mine and it has never let me down.

My thoughts for the day,
Gary

I bought my Merto several years ago from Sam.

I checked her over, built a heavy frame with a 7.5 ST head
serpentine belt and put her to work. No clean up, no bronze
gear.

I have about 200 hours on it and have had no problems. BUT after
hearing everyone's warnings and the latest posting of a members
engine failure I have decided to finally break her down.

I did the usuall break in and several checks of the bearings during
the 200 hours and it shows no problems but I sure don't want a failure
so this weekend I will begin a disassembly and rebuild.

Fear has me worried now !

Wish me luck and I will let you guys how it goes.
