What Size Lube Plate for B and W Patriot 16K 5th Wheel Hitch


Just wondering what size lube plate to get for my b and w patriot hitch. Thanks

Expert Reply:

We offer both 10-inch and 12-inch fifth wheel lube plates. The 10-inch diameter is part # RP83002 and the 12-inch is part # RP83001. My contact at B and W indicated either size is acceptable.

The best way to check for ideal fit is to measure out from the bottom center of the king pin half the plate diameters (5 and 6 inches). These are the points where the edges of the 10-inch and 12-inch plates will reach when fitted to the king pin.

If the edges of the 12-inch plate will stick out beyond the edges of the pin box, then you can use the 10-inch one instead. The plates are weight-rated as follows: 10 inch up to 22K; 12 inch up to 20K. Both have a thickness of 0.192 inches.
