YM1700 Fuel Pump

[pineknot42]

Haven't posted on here before and would like to say hello to every one.

I have a YM1700. I don't know how old it is but I recently overhauled the engine. It had a busted piston and the bearing were bad. I put rings, pistons, sleeves, bearing, seals and installed a water pump.

I have been trying to get the thing started. The compression is 480 in one cylinder and 500 in the other. I have bleed the fuel system as required. Actually several time to make sure. When I turn the engine over I get a little spert out of one fuel line and just wet out of the other. Not enough to even check the injectors. I even took the lines off at the fuel pump and there is barely any indication of fuel pressure / flow.

Now with all that behind me, is there anyone out there that has any experience in disassemble, assembly for the purpose of rebuilding the fuel pump? The pump I have is the banjo type. Don't think that makes any difference but just for more info.

I am familiar with mechanical work but have never fooled withe diesels.

Sure could use some good info and thanks.

Thanks Winston1,

I already have a tech manual for the 1700. I used it quite a bit during the overhaul. The pictures are hard to make out and there is very little info on the fuel pump.

If I do go ahead and go into this fuel pump I plan on taking plenty of pictures.
