4104 unable to move

Thanks Brian, like usual I think I ended up doing too much research, and was being way to safe.

Hopefully tomorrow I can bring it home.

You know, probably the most important thing here. Where is the bus and what is the serial number? Is it a conversion?

It is a conversion from the 70's it is bus number PD4104-3856 I will post some pictures once I get it home, I was so busy working on it today that I forgot to get them.

I think that I am the 3rd owner since the conversion and neither of the PO's did any updating cosmetically to it, just mechanical maintenance.

Here is a picture from around 10 years ago it currently looks exactly the same just more faded and the paint is flaking off on the roof and side stripe.

Looks nice.

If you burn out the clutch just moving it from that point, it is likely a bad clutch to start with. Those suckers last hundreds of thousands of miles.

Tried again today and it would seem that there is an injector that is not working correctly. Yesterday the bus ran ok after being in high idle for a minute, but today I was unable to put it on high idle whenever I did lots of black smoke would come out and the engine would idle very rough.

We replaced the fuel filter and added in some kerosene when we primed it. After doing this twice the engine would idle very well but still no high idle and stepping on the accelerator pedal would just smoke as well.

Does this sound like a stuck/clogged injector? What would be the best course of action at this point?

Did you trip the emergency shutdown flap?

So, I'm guessing you bought this bus without ever test driving it? You must have got one screaming good deal on it. Either that, or you're just about a crazy as the rest of us!

I did not trip the flap, is this how it would run if you did?

Definitely crazy like the rest it is a good bus and ran well a while ago but you know how that goes after sitting all bets are off.

Most likely lack of air. Check the air breather and blower intake. Might of sucked in a rodent

Activating the emergency shut down would act like that. It's just a big disk in the air intake that closes off air flow to stop a runaway. However, enough air does get by to let it idle. You just reset it by hand in the engine bay.

I assume you will have DD3 brakes. Just in case you did not know, merely releasing the parking brake valve does not release the brakes. You need to apply full force to the service brake pedal after the parking valve is released to unlock it.

Was that parking brake setup something on later 4104s? Mine has the handle that controls 2 huge pads on the output shaft.

pennuja · September 23, 2014, 01:42:02 PM

Thanks Lin I read that yesterday about the brakes and was going to try that today. I will definitely check the emergency shut down.

Mung you are right I am pretty sure mine had the handle and someone removed it but I could be way off.

Are there any big vehicles on site that you can use to pull it out or at least help to pull it out? Otherwise, what about using a come-along or winch? If you can get it to move with some other source of power, then it isn't the brakes or anything like that. Are the tires nice and aired up? Get them as full as possible if you want them to roll easy.

http://www.harborfreight.com/8000-lb-cable-winch-puller-543.html should be beefy enough to pull you out.

In your original post #1...you said you pulled the bus out of the ruts....were the wheels turning ot were they dragging ?

pennuja · September 23, 2014, 02:25:17 PM

I have it on flat ground now and aired up the tires today they were quite low. I think it should move now once I get it running again, I am going back again tomorrow and the first thing that I am going to check Is they emergency shut off. I also have a mechanic coming to check things out so hopefully I will get it going.

I was told that they were all turning, I was steering the bus so I was unable to see.
