I have posted about this before but never pursued it that far as it "ain't broke" well now it is. This shut down thingy came with my bus but does not appear to be OE. Any info appreciated.
The air cylinder that pushes the linkage to the rack is a little weird, it seems to be retracted when there is air or no air but in a weird twist of
? if the there is air pressure and you release the air pressure (via the handy shraeder valve or the solenoid thingy on the firewall) the rod pops out just long enough to shut er down.
The last time I started my always starts flawlessly bus, the engine hit ran for a few secs and then died. I tried starting again and it would no hit. Well it's nice to know your bus cause right away I suspected my little friend, so I removed it from the head and voila she starts on a dime as usual. SO looking at it I guess the push rod is starting to be a little out of adjustment, but I have alreadly adjusted this thing and there is a very limited amount of adjustment, there is very little throw in the thingy so it has to be adjusted pretty tight against the linkage so that when it is activated it pushes far enough on the rack to shut er down. You can see in this pic the linkage that the pushrod connects with.
I'm not really in a rush on this as I am parked for a bit but would be nice not to haver to use a stick in the hole to shut down.
and now for some eye candy?? here is an old MCI Courier that has wandered into the bus yard where my bus lives...
oh and before I get grief about the bad focus....I was out of batteries so I couldn't retake them
