I have a 1952 Seaman GM Desiel Tractor. On the "stop engine knob", I don't know if the knob should be in or out for the Run position. Also, there is a cable with a knob on the dash that goes down to some type of butterfly mechanism on the blower. I also need to know what this does. Thanks for your help..... ..

Most GM diesel stop knobs are in for running and out for stopping.

Without seeing how the "Stop" knob is set up, I can't tell you for sure which position is "run".

The knob connected to a lever near the blower is an emergency stop, which cuts off all air to the engine. Under certain conditions (blower seal failure, for one), the engine will suck in and burn it's own oil, and overspeed until it blows up, or seizes. The emergency stop is the only way to shut it down when that happens, as shutting the fuel off will do no good.

Bob, thanks for the information. The "stop engine knob" is hooked up to the govenor. I hope this will give you enough information to be able to tell me which position the know should be in. Thanks....

SL - Every diesel I have ever operated or worked on (including a Seamon with a 4-71 Detroit) has been arranged for the engine shutoff to operate as a "pull to stop". That's not to say there's a few out there that are setup for pull to run, but it's unlikely.

Also keep in mind the Detroit diesel's emergency stop knob works as a "trip" for the blower damper. After the E-stop knob is pulled, damper must be reset before the engine can be restarted: Push the E-stop knob back in, then manually latch the blower damper back open.

(If you ever get into a "no start" situation, check first for a tripped blower damper....don't ask how I might know this!)

Good luck - the Seamon is a cool and unusual tractor!

Bob M -- Thanks for the information on the emergency kill on the blower. It enabled me to get the Seaman tractor started. I reset the blower damper. The problem now is on the stop engine - it does not kill the motor. When the knob is pushed fully in it does slow or retard the engine, but it does not stop. Is there any adjustment to the govenor that would take care of this? The stop engine cable does go to the govenor. Thanks for your help..... .....
