Waste Motor Oil / Re: 3/4" needle valve

Mike,

Very nice job there. A very good furnace and cooking surface.
With winter approaching, you will be the one that the women of the tribe choose to breed with  ;D

cheers

Here's a theory ...

If I am looking a the correct valve, the marks indicate that the de-comp lever is only contacting the edge of the rocker pad.
Being that the valve cover is held in place by a single stud in the center, the cover can be rotated somewhat to the left or right once installed.
Is it possible that the valve cover is being installed slightly rotated enough to make the actuator completely miss the rocker?

Also try holding the valve cover slightly rotated CW when installing. Then try again holding it slightly CCW.

See where I marked on the picture below....

just a thought,
Veggie

Yes, the Changfa water cooled diesels are amazingly tough and durable.

bigbad,

China has never made Lister clones.
They are made in India.
Rajkot, India to be precise.
They are no longer allowed for import into the USA.

   CUSTOM ST-5 LISTER(OID) SERPENTINE PULLEY

This is a custom machined pulley for an 1800 rpm generator head.
When coupled to a Listeroid with the standard 23" flywheels, it provides the correct ratio
to drive the generator head at 1800 rpm.
It uses a standard automotive flat surpentine belt.

It also comes with a 38mm shaft bushing to match with the shaft of an ST-5 generator head.
Solid steel. Weighs about 15 lbs
Price: $135 CAD

Can ship anywhere in Canada at owners expense.
Send me a PM if interested

Lister Market Place (things for Sale) / ST-5 5KW Generator Head FOR SALE
« on: August 15, 2021, 03:42:55 AM »
  Power Solutions ST-5

I have a "POWER SOLUTIONS" ST-5 head for sale.  1800 RPM, 5KW max rated.
This is the version that was imported by John Fergusen in Ontario and modified with better quality bearings.
John also removed the stock junction box and replaced it with an approved version.
He then got the units Canadian [ETL] rated.

This particular unit has approx. 5 hours use.
It was assembled with a Listeroid CS6, and then promptly disassembled when a friend of mine bought the engine.
The ST-5 has been in storage since (4 years).
 
Price: $ 450 CAD  (Considerably less than I paid for it)
I can ship anywhere in CANADA at the buyers expense.

PM me if interested,
veggie

The work that these Changfa single piston engines can do is unbelievable.

"I always found it fascinating, these overhead shafts would run in wooden blocks as bearings, and pretty much last forever".


Yes, they are amazing... until you forget to lubricate them with pig fat  :o     Then they catch fire

I agree, there should be no issues with what you are planning.
Some people buy a multi-groove pulley and run 2 belts from the same side of the crankshaft for 2 separate loads.
(2 loads driven by 1 pulley)
One advantage to running two loads in opposite sides from the same pulley is that the normal belt tension side load on the crank bearings is offset by the two drives pulling in opposite directions. ( if that makes any sense  ???  )

Changfa Engines / Re: Chagfa 175 CHP unit - First Test
« on: July 19, 2021, 03:45:32 PM »

The engine only sounds quiet because my system is designed to run at 1150 rpm.
If I ran it at 2600 rpm with full output it gets very loud. (Typical Changfa type engine.)
The pulleys are sized so that the generator spins at synchronous 3600 rpm when the engine is turning at 1150.
This limits the system to 1.3 kw max output at 120 volt AC.

To modify the engine for an external oil filter you will have to confirm that your engine A] Has an oil pump and forced lube system. B] The engine has a removable filter screen that can be modified.
I don't have pictures available of the modification, but the the objective is to remove the cover giving access to the pressurized screen filter chamber.
Remove the screen filter and machine a plug that fits into the filter chamber. The plug has holes and an o-ring which re-route the incoming oil to an external port. Through the filter, and back into the screen chamber, then onward into the engine. Each engine size probably has a different sized screen and chamber so each mod is custom to the owner.
As far as I know, only engines size 175 and larger have the removable screen cover. Smaller units (160,165, 170) do not have this feature.

Your assumption of approx. 1/3...1/3...1/3 power between crankshaft, coolant, and exhaust energy is correct.

Gathering exhaust heat however, can be messy and difficult. Soot and carbon clog exhaust heat exchangers very quickly if not designed correctly and if exhaust velocity is not sufficient. Even then, regular cleaning may be needed.

Here is another example of an enclosed system that a fellow built. Provides power and heat.

Did you have to adjust the timing on the fuel pump to get it to run at that speed or were you able to do that in the factory configuration (minus the lighter spring)?

No modifications other than the lighter spring on the throttle.
Engine speed is 1150 rpm.
It can go slower than 1150 in it's stock form.

Something looks wrong there.
The babbit appears to be scored (lighter grey material) and the section near the end of the shell (darker grey) looks like it's not contacting the main bearing journal.   ???

Hi Mike,

That one you linked is for hydraulic service and has a one-way check valve in it.  Gravity won't open the check, so unless you can remove the check valve I doubt it will work.

cseyfert,  ... Good catch !

Mike .... remove the check valve  ;D
