4104 unable to move

[eagle19952]

somewhere back in the thread/post he said that they pulled the bus and the wheels turned....would seem that the  brakes are released...

Thanks to all of the help from here I have my bus safely at home. The emergency shut off was definitely the cause of the bus not moving and not running correctly. After reseting the emergency shut off it started right up and reved up perfectly, however I do have a small issue with idling my idle seems to go up and down constantly.

I can without a doubt say that the black switch is not an parking brake or mine is not working correctly. I was cleaning out the basement storage and the bus started to slowly roll away after about an hour of it sitting there, luckily I was able to jump in quickly enough to put it into first gear and stop it.

I also found out that I am completely unable to downshift from any gear. I read RJ's shifting guide but due to where my bus was I did not have a chance to even try to figure out the shift points. I will need to read through it again and practice by my house where the roads are empty. I can without a doubt say that it was the most fun that I ever had driving I am sure I was smiling ear to ear the whole time.

Thanks again everyone that helped me out!

i still think you have shifter linkage and/or clutch adjust problems...
does this have a twin disc or single disc ?
does it have a clutch brake ?
i guess i could go read the book cuz i don't have a 4104 to look at...

I am not sure about the single/double disc but it does shift up really well, I think I just need to learn to down shift. I tried everything but I stink at it. I am able to get it to go into first when I am rolling slowly but that is it. There could certainly be something wrong with the clutch adjustment I will try to check it out tomorrow night.

I am uploading a few pictures of it from tonight, I will post them soon...

Downshifting is an art of matching the engine speed to the gear speed. Most likely, you are not applying enough throttle when downshifting. Eventually, you'll get it.

I am concerned for your safety (and that of others), though, if the bus started rolling away after you had parked it. I do hope you chock the wheels until you get the whole parking brake
thing figured out.

keep your rpm's up....and your chin...
i will look in the book here soon

edit. no clutch brake, single disc..do you recall the free pedal amount ?

Yeah chocking the wheels is a definite until I figure out a better solution. It was a frightening experience and will never happen again, if I did not get in there at that moment the bus would have ended up in the lake (no one would have been hurt). The PO had used that as the parking brake but it obviously is not.

Definitely not enough RPMs I know that for sure, I was also in traffic going light to light so there was a lot going on and to much to safely try anything that kept me from concentrating on the road.

one thing that works for some .... concentrate shifting between 1st 2nd 1st till you get it then add 3rd... the add 4th...

Here are some current pictures...









I believe that the area that the silver mesh covers is the location of the real parking brake.


Here is a horrible picture of the two air brake buttons that I have, only the one does anything.


Here is a very dark picture of the front of the bus.

You are not the 1st to chase a 4104 when the air pressure drops

Good luck with your new project, you're fortunate that others here with experience with your bus model are so willing to share their knowledge, you're in good hands.

From the position of the driver side mirror it was never a hound!

Why do you say that Gary?

[usbusin]

Hounds had the drivers side mirror low like on the passenger side.  See my avatar picture; drivers side mirror high; never was a hound.  Original customer was a private bus company.

I notice that you have two buttons? One maybe just for holding on a hill and the other is a true parking/ emergency brake.
You also need to remove the screen and see if the rear brake chambers have three hoses going into each one. Do you also have an emergency brake lever? If so, it applies shoes to a brake drum on drive shaft. If it does, don't apply it for the FIRST time where you don't want to be stuck in case it freezes up from lack of use.
The shifting characteristics change as the transmission warms up to hot. Faster shifting when cold and slower towards hot. When pushing in the clutch when hot, it can take 20 to 30 seconds for gears to stop turning so you can engage first. They should eventually stop with clutch in(sooner when cold). If not, then some clutch adjustment or more to stop it from dragging. A dragging clutch can exasperate changing gears. Is that a tach in top center of dash cluster?
