fordson dexta throttle problem

Scott Hansen · Jul 9, 2010

I have a 59 dexta that I am trying to fix. I fixed all fuel leaks and am adjusting the timing now but the throttle lever won't work right. If you put lever up to low idle it just falls down to high idle. Is there a spring or something that makes it work? Also on the intake manifold there are two copper vaccum lines one off the side goes to the injection pump diaphram but where does the other line go to? Right now one end is on the intake manifold and the other end is laying by the sediment bowl with a threaded connector on it but I cannot find what it connects to. Help Please! If anyone has some pictures of this can you please send.

Scott, also try "fordsontractorpages.nl" and go to the "Dexta forum" as a lot of your questions are answered there.TSG.

friction disc on bottom of throttle is gone or worn out.

Working on a super dexta now. You mystery line should hook to the fuel shutoff. Dextas didnt have a sediment bowl. They had a shutoff with a primer built in for cold starting.

The small line to the intake squirts diesel onto the heating element in there and the engine then sucks in flaming diesel fuel to help it start.

The shutoff is available for around $120 online. Mine is broke but I'm going to try to repair before I spend $120.

I believe the throttle return spring is in the injector pump. There is a friction washer setup to hold the throttle where you want it, but it should return to idle if its slipping. As a note, mine has the mechanical governed pump and I assume you have the pneumatic, so yours might be different.
