General Information

SD DM 18.02.01

Important: Before operating the Premier coupling, refer to the Premier web site atwww.premier-mfg.comfor complete safety, operation, and maintenance instructions.

Trailer couplings, used only on trucks, are attached to the rear closing crossmember.

The Premier 260 and 460 trailer couplings have a rigid pintle hook, and are air-adjusted. An air chamber, mounted forward of the coupling, operates a pushrod, which pushes against a shoe inside the coupling. The shoe maintains constant pressure on the eye of the trailer drawbar when it's over the pintle hook. See Fig.. This takes up any slack in the trailer connection, providing smoother towing and less wear on the pintle hook. The air pressure is activated when the trailer brakes are released.

The Premier 690 trailer coupling has a moveable pintle hook, and is non-air adjusted. It is used for heavy-duty applications. See Fig..
