Capture Plate Adjustment Procedure for Demco Hijacker Autoslide 5th Wheel Trailer Hitch DM8550034
Updated 04/11/2018 | Published 04/09/2018
Question:
The arm that you pull to unlock the hitch isnt locking into place and I cant tell why. I also read that the silver guides should should be loosened before you land the trailer and tightened after the trailer is landed, is this correct.

Expert Reply:
The silver capture plates on the Demco Hijacker Autoslide Hitch # DM8550034 should be adjusted after you hitch the trailer. You want to push the capture plates against both sides of the pin box then finger-tighten the inside jam nuts against the capture plate mount. Then tighten the outside jam nuts against the thick mounting plate. This is covered on page 3 of the instructions, which are linked for you.
The procedure to uncouple the king pin jaws appear on page 7. Demco notes in step 5 to install the safety pin if the handle will not stay in the out position.
The manual also covers the important routine maintenance to keep the hitch in safe working order.
