Well, figured I would finally post about this. Got this China diesel to work on, seems to be out of a boat at one point, as it has a forward-neutral-reverse 3:1 reduction marine geabox hooked to it. The engine and gearbox was manufactured in 1984 and I believe the engine to be a ChangFa CH170F (tags are worn and no model present, only the date). this beast is heavy as sin, so it went straight from my truck to... the handy dandy wagon it is sitting upon. Anyway, today I have done the following, built a new hand crank since it did not come with one, and the starter was broken at some point before I got it. I then cleaned the old water infected diesel fuel out of the tank, lucky for me the shut off valve was clogged so none got thru the system. I also added oil to it and a fuel return line. About this time I got tired... but did get pics (next post). So far I can see how to make it run, but not stop... any suggestions??

Anyway, plan is to get it running and build a simple homemade tractor around it lol.

From what I've read, these engines were intended as stationary engines, but people have put them on GT's with no ill effects. In a boat after all...they rock around like on a tractor would do. Hope she runs with with very little work!

Looks like a nice engine Casey. Glad you were able to make the trade. Hopefully you get it on your round-to-it list soon, love to see what you come up with.

If nothing else, shut it off with the fuel shutoff you mention being clogged. If it's still functional, then just cut the fuel and see how long that takes to cut it.

Take some close-up pics of the injector pump. Maybe we can figure it out. Is the slotted adjustment to the above left of the hand crank the throttle? You may just move the throttle all the way down to shut it off.

The whole system looks to be in good condition. Wouldn't think it would take too much to get it running.
Is there a name plate on the gearbox with any information? Looks like a good option for putting a diesel into a golf cart.

You are no too far off, I am thinking of using a golf cart front and rear end I have in my shed to build the homemade with when I get the diesel running. One speed fits all, forward and reverse lol.

Those Chang Fa engines are a high quality unit. It looks like that one has the total loss water cooling system. You can get water pumps and rads for them I think.
Are you sure it's a genuine Chang Fa. You could have a knock off engine or a WEFOOLYOU engine as they are commonly called! Seriously though, those are popular with the off the grid folks and people in remote areas that use them to run gen sets. They are easy to adapt to running on bio diesel or veg oil. I think they are a clone of a Yanmar engine if I remember correctly.

Not certain on brand name, just calling it a ChangFa for now... It is definitely a heavy unit, and air cooled, not water.

Air cooled is good. Makes the install much easier.

I just want to hear it run at this point. So tonight I'm going to be reworking the fuel shut off so it will actually work, and also bolt the engine to the cart. I might actually get to try it tonight.. Mabey.

Did you get it running yet? I dont think its a yamar clone, those are the upright air cooled with the alum blocks. These lay down style are a clone of something else. They are NOT smooth when running, quite a shaker. I had one of them a few years ago, was going to stick it on an old wheel horse but the vibration was to much. They do run well, just bolt it down to something really good. Mine could be shut down by moving the slotted throttle to the lowest postion, this would stop the fuel at the injector pump by closing the fuel rack. Good luck on getting her to start. Mike

No, I never did get it to start and run. I have a 120 volt AC motor sitting next to it as plan c to get it cranking lol. If that won't do it nothing will.
