Strange problem with 6V92 shut off lever

[buswarrior]

If adding an oiler to the air system was needed...

Wouldn't we already have one? he asks rhetorically...

Shutters and that's it.

If there is an offending accessory device, and you've decided that a shot of lube is the solution, understanding how oil and rubber may not like one another... do as eagle19952 suggests, loosen the air line to that device, give it a drink, close up the connection, and blow away.

Please, do NOT oil the internals of any brake related devices, for sure, no exceptions. Having the rubber seal in one of those swell and stick at the wrong time, in the wrong position... dragging brakes burn down buses...

happy coaching!

Not sure why this thread morphed into an oil-in-the-air-system debate.  The problem is not related to the air system. It's all about the fuel rack shut-off lever sticking. The OP even said that in the third post.

But, maybe we can discuss the DD3 brake chamber parking mechanism next!

I quit using those old antique DD3's and updated to the new and improved DD7's!

Once again it was me, the newbie here causing trouble :-)    I had a sticky shut off solenoid too.

So Gumpy could get his dig in..

i found the problem... 2 problems actually. The cylinder was a little sticky, and oil resolved that; also, some of the exhaust pipe insulation had deteriorated /shifted and was blocking the shutdown lever. If I moved the insulation the shutdown would work. Once I oiled the cylinder the shutdown would work without moving the insulation. The pain was I had to drain the coolant and remove the coolant pipe to see what was happening.  All fixed now. Thanks for all the help!

Just be sure to bleed the air out of the coolant system before any long trips. Most MCI's have bleeder valves on both front and rear cross over tubes on the engine.
short trips and keeping the coolant full will do the same thing if you don't have the bleeders.

On my old MCI 9 mechanical 6v92 we had the same issue. That level seizes up and we had to manually put it back in the run position every time I shut it down so it would be ready to start again. Dealt with this for a year before finally just taking the casing apart, pulling the washers putting new ones in, cleaning up the lever shaft, lubing it and reinstalling.
