King Control Throttle System


Recommended Posts

This applies ONLY to mechanical, Cummins, diesels, such as the C8.3 with the King Throttle & Cruise Control.
 
As most know, there is NO longer any support for repairs to the King Control.
 
If it fails you will be faced with a conversion to a old fashion wire throttle or air throttle.
 
We have completed a conversion to an Air Throttle on a C8.3 and it works exactly has hoped.
 
If you have interest in an Air Throttle Conversion, please PM me, happy to share the information.

I am interested in more info. I have a 96 Windsor with the King setup. I seem to be having some intermittent issues but it is at least still working. Also my cruise control just died on my last trip.

So it’s probably time to start looking for an alternative!

 

thanks,

Mike

How does one determine what type of throttle they have? I have a 2003 Executive. I have heard about this issue but i am clueless as to what Monaco/Roadmaster installed.

Hello:

I assume your engine is a Cummins and most likely being a 2003 coach you have an electronic engine; ISB, ISC or ISL ISX or maybe a M11 etc.

Monaco's from 1997 and earlier used Cummins with a mechanical fuel injection system which used the King Control for Throttle & Cruise Control.

1997/1998 seems to be the transition years from Cummins mechanical to electronic engines.

The Air Throttle Conversion was done on a Cummins, C8.3 with mechanical fuel injection to replace the King Throttle Control.

Paperwork with your coach should identify the engine model.

I have a 1996 Dynasty with a King Control Throttle.  Please send me information on the conversion to an air throttle system.

I have had many problems with my King Control and would like to convert to a better system.

My email is:  ljohns0721@gmail.com  and my phone is 310- 375-6079.

Thanks, Larry Johnson

I am sure that quite a few of my fellow Moacoers are in the early 2000s range of coaches. I believe that my 500hp Cummins is an ISL. I've been through a lot of paperwork over the years but don't remember seeing a section detailing the throttle control. 

Sooooo what say you group, where does one start this information hunt?

Thanks Ken

I  also am interested in a replacement for the King system.  I have a 1998 Executive with a 8.3 Mechanical pump.  I currently have issuers with the system and would like to replace with a newer serviceable system.  It looks like this subject is popular.  Could the information be placed in the downloads section for future reference?  My email is : hickerson.richard@gmail.com.

I will likely be interested in this info at some point. Why not just share the info here so when people search for info they can find it?

Hi Jim

At this time, we do not have much to share.

Our effort to date is to determine if there is interest in a Basic Kit of Parts.

We have just gotten quotes back from our machine shop and hopefully will have more share very soon.

We are NOT a commercial company just two guys trying to help the RV Community.

It is our intention to make ONE RUN of parts and DONE, to be provided with detailed instructions with photos, parts list and sources of all parts.

Regards,

Charles
