You will have to do it manually at the back of the bus. I think there are some pictures posted here or on the other board that show the location of the valve if you do not know where it is or what it looks like. |

Jim,
All of the mechanical Detroits require air pressure to operate the shutdown lever. The cylinder is located in the middle of the Vee, only about three inches in from the "front" of the engine. If your bus has fast idle, the fast idle cylinder will have a tee in the air line, with one cylinder preventing the throttle linkage from moving, and the other is further down on the side of the governor. The stop cylinder, which has one air line, straight from the bulkhead, pushes on a small lever which stops the governor. You can push this lever easily with your thumb.
The emergency stop button may or may not fully stop the engine. If you stopped the engine this way, you will have to re-latch the flapper, which is up on the side of the air intake, with a small cylinder with one wire connected to it.
Hope this helps, and that you've already got the engine stopped!
Regards,
George |

just so's you know, all detroits may have started needing air pressure to shut down but some (at least mine) have been moded to need pressure release to shut down. the shut down rod(straight off the valve head) only closes the rack after the cylinder connecting it has been pressurized and then had the pressure released. I have no idea why it was set up this way just know that POs can do some crazy things...I think I may have the shut down system of some other diesel engine fit onto mine...if anyone recognizes what I"m talking about I'm all ears.

Patrick,
If yours shuts down with pressure release how do you ever get it started when you have no air pressure?? |
