No throttle on cruise or foot throttle? Both? Do you have the schematic for your coach? Can send a PDF.

if air cruise maybe the air cylinder needs to be serviced and possible potentiometer at end of cylinder. I had bad throttle control with the 95 240 and after taking this all apart and greasing internally it was no more problem.

Yes, the Bendix system is pretty simple (the throttle part).  Strictly AIR.  I would take loose the line at the Bendix box (front of engine compartment) to see if air comes out when someone steps on the throttle (yes, with coach air pressure up).

Doug,

Can you be more specific as to what is broken?  I had some problems with my throttle cable about 3 years ago, and did a extensive search for a replacement.  My conclusion: they are unobtainable.

The part number on my original throttle cable is "MORSE 303192  47.8"  5745".  You can look around, and see if you have any luck finding one.  As you have already discovered, the Bluebird owners have this same throttle system on some of their coaches.  I found threads on their forum about the cable, and attempts to replace it or repair it.  But NOBODY (that I am aware of) ever found a source for a new replacement cable.

What I finally did was "rebuild" my cable.  I disconnected it at both ends, and took it to my bench to work on.  I found both of the unique ends were still firmly attached to the inner wire core.  On mine, the problem was the outer covering for the cable was disintegrating from heat/age.  I used a combination of rubber tubing, metallic tape, and heat shrink tubing to pretty much restore the whole outer covering.  By simply doing that,  I restored the proper function of the cable.  It has been working fine for a year since I finished that project.

I documented this in a thread back then, but having a hard time finding it...

Search (advanced) on throttle cable with user Chuck & Jeannie turned up

among other threads.  Is that it?

Doug,

Glad to hear that your problem is most likely "solvable" by rebuilding the cable.  ^.^d    Let us know how it works out.

While I've got your attention, I noticed on your Profile page that you have entered your build number as 15760.  This is incorrect.

The coach build number is the 4th through the 7th characters in your "Model No." found on your factory data plate.  See photo below:

What about throttle cables for outboard motors? Would one of those work? They come in different lengths I believe.

As Doug says (if you can read shorthand), it's not the length that is hard to find - it's the correct cable end connectors.  One end has to screw onto the CC-5 air cylinder (see the diagram in my earlier post).  To the best of my knowledge, this properly threaded and correct diameter fitting is not available on any currently produced "engine control" cable.  Some of the Bluebird guys tried cutting the end off a original (broken) Bendix cable, and attaching it to a new cable.  It didn't work.

I have wondered about a hydraulic throttle, to replace air or Morse cable. Master cylinder and slave from a car clutch system. A company named Neal used to make these for hot rods and dune buggies.

Looks like "manual" control.

Had to do that once on I 10 when the Bendix air vent clogged (diagnosed the next day when I had time to tear into it).  So throttle would not release.  Like you, line to the front.  A little complicated when maneuvering.
