My father in law owns a Ford 1900 that apparently needs the diesel injector pump rebuilt. Tractor hasnt been started in 5 years. Getting fuel out of each injector but just wont turn over. Changed glow plugs, fresh battery and fuel, new starter at the time. A year ago i found a company online that specializes in rebuilding these pumps. They even had photos of each pump they serviced and i saw a pic of this one. I cant remember the company name. Can anyone reccomend a reliable company that services these 3 cyl pumps. Shibaura engine and pump says Kiki on it. Im on Long island NY but can ship to a company if its a better option. Thanks,Paul

Fordin631,

Injector pump rebuilds are very expensive. Before you go this route, there are several other things that should be checked.

You mentioned that the tractor sat idle for several years. In many cases this will cause a small amount of rust to form on the cylinder walls. In some cases the rust can get so bad that it will prevent the engine from turning at all.......which is commonly referred to as being a "stuck" engine.

Since your engine seems to be spinning over just fine, I'd venture to guess that you've lost the seal between the rings and the cylinder wall.

The fastest way to check this is to remove the injectors and then plug the holes so that no debris can enter the engine while you're working on it.

Insert a compression test gauge into the first injector port, then turn the engine over with the starter a full five revolutions. The compression test gauge will record the highest pressures produced during those five full revolutions.

Continue this process one cylinder at a time, recording your results on each cylinder.

A diesel engine will not fire unless there is sufficient compression to produce the heat needed to cause the fuel to burn. Low compression will prevent the engine from firing.

A good compression tester is a handy thing to have around.......but there's no need to buy one. Most mechanics own one.......but it has to be designated for diesel use. Gasoline engines don't produce nearly as much pressure as a diesel.

Should you discover a low compression pressure, your solutions are limited. It may be possible to get a good seal between the rings and the cylinder wall by pouring a bit of kerosene into each cylinder and letting the tractor sit for a few days. Just pour it in through the injector port opening. Pour about a half-cup of kerosene on the top of each piston. This will help loosen the rust, possibly helping to cure the low compression problem.

Hope this helps.

Joel ....

I am sure you have a pump problem if your father in law did not change the oil in the pump, those have to have the oil changed when the engine oil is changed, and they must be periodically checked for oil level.
I inherited one of those as well, so far it is not good news, very expensive to rebuild, looking for an alternative.
:-(

good luck to you. ....
