  1. I have been working on an identical engine. Early UD 18 c/w american bosch injector pump.
  2. Anyone got an ext UD or TD 18 exhaust manifold? I need one
  3. Anyone got a good american bosch APE pump for a UD 18?
  4. You are going to have to get a good line of sight so you know what you are doing. Take a right angle pick and try to flatten it a bit with a hammer so you got a better chance of seperating the ring. Good Luck
  5. Maybe no one is interested but this is what I done to my Fuel system. So problem is when running on gas mixture is very rich. Carb has a fixed main jet. Removed the jet and drilled out the orfice and tapped to 8-32. Check the hole size before drilling was about .072. Made a jig to drill out a brass screw which I cut down to the right length and drilled it to .060. WHAT a difference it made. Now I can try to get the diesel side working. Governor not working in american bosch pump.
  6. No it doesn't run ok. The spark plugs that where in it where really old. But they where clean. So it couldn't have be running like it is. You can tell when you find a problem part by the bolts. As in something has been apart alot. The screw head on the carb are VERY worn. Tells me it has been apart toooo many times. Waterloo
  7. Ok guys I am looking for some input. I am working on a UD18 power unit. When I bought this I was told it ran good on gas but the pump had two seized elements. (Bosch pump). SO I have changed the pump and have been trying to get this going. I am have MAJOR problems on the gas side running VERY rich. So I did change the needle and seat. But that is not it. Tried it again today but it is still rich. Is it possible that the fuel jet in the carb is too big? I don't have anything to swap it with but I may measure it then drill it out and tap it so I can make a jet and screw it in. Whatya think
  8. Must say they are all running pretty sweet! Do you own shares in a company that makes block heaters?

    what the story on the pick up. Being sold?
  10. If you are going to try an fix this without removing the pump you will need to do some major cleaning before I would open that pump. W
  11. See if you can find a copy of an N manual that show the disassembly of the pump. For sure you will need to remove the plunger unit. W
