Does anyone have any tips or tricks for removing the CruiseKing in my '96 U295 8.3 mechanical Cummins?
If anyone has experience with this in DFW, I'd appreciate some guidance. I'm not highly experienced mechanically.
Feel free to contact me 817.675.1623 by text as I'm a school teacher by day and Realtor by night and weekend....although I much prefer Foretraveling! 😊
Hope someone has texted you. It's the box under the bed in the right front corner of the engine compartment. Has some electrical connections that have to be disconnected, and a cable to the injector throttle control arm that is disconnected at the arm. Then remove the screws or bolts that hold the box in place. There should be 2 spiral springs about a foot long connected to the throttle. There purpose is to close the throttle and retract the pull cable when you take your foot off the go pedal. Don't believe the springs have to be removed, can't remember, but they should be there.
Thank you! No, no one has texted or responded. I appreciate it! Looks like I'll be doing it by myself, but that's okay too! It will make me better able to help the nex5 fellow! Thanks again, I'm sure I'll have my iPad right beside me reading you4 response as I'm removing it! 😊
The 2 springs can be gotten at lowes.
why are you removing the King Cruise Control? Where did you plan to send it? What is your symptom?
I'm sending it to Steve Boller at KingCruise.
Symptoms:
Lack of down shift trying to accelerate at 60 mph
Won't gain speed over 60 mph with foot pedal depressed but will with cruise stalk accelerate
RPMs max out 1800
cruise gaining speed after being set
Won't downshift to try to maintain speed at slight rise in road, just steady loss
Yes, I hear about those springs, they go to the throttle, right?
Have you done this David?
Sending your box to the right place. Know Steve and have stopped in his town. Sounds like the right thing to do.
Remove any slack in the pull cable, so that the first King movement moves the injector throttle bracket and to eliminate injector pump. Looking at engine with engine on or off, while activating the throttle may help identify problem. Also reach down to manually move throttle plate.
That same injector throttle bracket should have two long 'screen-door' springs attached to fixed bracket at bottom of engine. We found that the spring-steel of the spring loop ends are stronger than the holes where they are attached causing the holes to wear and partly cut through. Important to find springs of about the same diameter and same pull to not fight the King Throttle Control. Springs we found at Lowes/HomeDepot were too long, so we cut them to length and twisted a new end loop. We carry a few spare springs. Two springs may be redundant making sure the throttle bracket returns back to idle position. It seems that if springs are missing, nothing will move the throttle to idle.
As a test or to travel without a working King Throttle, we and others have rigged up a cable to manually move the injector throttle bracket. One time for a short distance, with bed up and a 2-way radio with directions from Cindy driving, I pulled up on bracket to give her throttle. Another time needing to drive a long distance, made a wood hinged foot throttle for the driver's foot pull a long cable that was fed through the front of the bed. Both manual throttles worked just fine and quite safely got us to our destinations.
I had Steve rebuild my cruise control, it came back looking like new. Well it was away getting rebuilt I ran a wire from the throttle
to my fuel peddle. Everything worked but the transmission didn't shift as well as without the cruise control the transmission doesn't
know where the throttle is. Have you phoned Steve, he is great in helping trouble shooting the control. Taking it out is straight forward. Good luck.
While you are working this examine,or better, clean the contacts on the taillight switches. They are located in the first driver side bay against the forward bulkhead. They may not be the root cause of your issues but will cause similar symptoms.
I solved my problems with the King Control 10 years ago by installing an air throttle, the King box is now just a Cruise Control.
Springs for the 8.3 Cummins are made by by Century Springs and individual number id C-315. These springs do not have to be modified they are the right length and ends. I found them at Elliotts hardware in Dallas but any good hardware store should have them.
