Why is the top plate the most common fifth wheel repair? It’s under intense stress while in use. This high stress can damage the plate and normal wear can break down internal, smaller components like manolla mehlahare le mesamo ho kenya lesale, bushings, release handles, and more to the point of replacement. You may also struggle with fifth wheel top plate troubles if your coupling attempts aren’t in compliance with JOST’s Operating Instructions or the industry standard TMC RMP-654.

1. REVIEW THE TOP PLATE’S SURFACE

Pull the release handle out and hang it on the release notch; it must be flat and straight. Then ensure the adjusting screw shows ⅜” to 1 ½” of threads. If it shows less or more than that, there is an issue. 

If no issue is found, scrape any excess grease from the top plate surface’s recessed center. Check the cushion ring insert for any chipping or damage, and make sure the locking bar tip protrudes further into the throat than the coupling guide lugs.

You can also inspect your top plate and diagnose any issues by looking underneath it. First, verify that the lever with the bushing is in appropriate condition and position. Then check the pivot bolts to ensure there’s one washer between the lever and castellated nut on each of them. Finally, check the release handle attachments to ensure proper attachment.
