What I have is a PHW-1 clone that is bored and stroked.
Really its not 10 hp as built because of the displacement increase.
It was imported years ago as a replacement engine for the mining industry and that idea did not take off after the crash in 09.
This engine is water cooled with a replaceable wet liner
Mine was special ordered back in the day to use the same parts as the KOEL DM-10 so parts would be easy to get, I just added the electric start option.
I’d like to see it go to a good home.
Failing this it will be donated to the local high school as a teaching tool.
Yes it has a steel crank and full oil lubrication and not TRB like a cheap unit.
I even have a spare crank but its suffered from rust damaged from a decade of storage,
Could still be used if polished, but if I wanted it to be used again I would consider having it rebuilt.
I think I have 3 or 4 sets of complete replacement bearings for the machine too.
Yes it is still made.
These will probably still have parts made in 50 years.
They are very common in Africa and India, middle east.
