'68 Ford 5000 diesel - where is the timing adjustm

Why?

The diesel engine is not like a petrol and the timing is set by the manufacturer and to vary it from that setting is to ask for trouble. If you have a timing problem it will usually show up in either black or white smoke but there can be many other causes too.

The timing is adjusted by setting the engine at 19 degrees in the window on the rear plate under the starter then either, remove the plate on the rear of the pump, place a pointer in the grove on the shaft and see if it lines up with a mark on the front housing or drain the radiator and remove the bottom hose, remove the front plate check that the marks on the drive gears line up exactly. If they do not, slacken the three bolts on the pump drive and move the pump until they do. This is the sequence for the Minimec pump.

Thanks again.

Thanks.

Though this won't get you to far.. if you wanted to try to see if the miss was isolated to a single cyl, you could crack the fuel line at each cyl, one by one to see if the miss modulates.. etc. however as i said... injector / pump problems are best decided by a rebuilder with the equipment to do pop off tests and other such diagnostics.

In the end.. might be just as easy to get the tractor carted to a mechanic, caus if you do pull the injector pump off.. you will then have to get it set back to the engine time.

good luck, and keep us posted.

Black smoke can be air or injectors as others have advised but it could also be that someone has tried to adjust the fuel delivery on the pump to get more power.
