Troubleshooting Demco Hijacker Jarring and Chucking at Start and Stop

Question:

apparently have one of the earlier versions of the 18K demco hijacker, no matter how many times I adjust it, when I have come to a stop and then take off it feels like there is slack in something and it jerks and pops , it operates fine except that, is it the design with just the locking bar or something else ? I see the new head has a traditional locking device, and looks more secure, was wondering if this is a fix for the clunking ?

I reached out to my contact at Demco and he said that depending on the year, there was a gear adjustment bolt on the cab side of the base of the older Hijacker models. He also said some of the slide bar heads had an adjustment bolt there as well for a better king pin/pin box connection. These adjustments should clean up the slop that you are experiencing. If you have your owners manual it will walk you through those adjustments. If you don't have the manual, let me know your model number and send a photo and I'll see what further troubleshooting we can do.
