Fuel cutoff MD11c

[jwspeck]

In monkeying about with the engine, I started to wonder how the fuel cut-off works on the MD11c as I was wondering if mine somehow got messed up and is actually causing the engine fuel problems.

There is a piece of metal on a rocker. When I pull my control line it pulls the top of the lever so that it is straight vertical and the bottom of the metal lever contacts a metal pin that sticks out the engine.

Is that pin supposed to push in to the engine? Mine doesn't. It sticks out about an inch and doesn't budge. Or does the metal lever contacting the pin close some sort of electrical connection?

I've looked through the volvo manuals that people have pointed me to and I can't find the section that talks about how the fuel cut-off works or is plumbed.

Any help?

The pin is designed to push into the engine, which cuts off the fuel thus stopping the engine.
The process is entirely mechanical

Ah, thanks! I think my pin is jammed open :/ I saw on the schematic there is a spring and other thing in that hole. I wonder if I can I fix this without a major disassembly of the block...
