Cables: Check the cables for crimps (bends) or signs of wear. If a cable has a crimp in it, that instantly reduces its strength by at least 50%. A crimped cable should be replaced right away. Signs of wear may include flat areas, shiny spots, or broken strands. A cable with broken strands should be replaced right away. A cable with other signs of wear should be watched and replaced soon. When checking the cables, be sure to check the entire length. This means you’ll have to check them with the bed in both the full up position, and the full down position. If you do find wear on a cable, try to find out where it’s coming from; this will save you from experiencing the same problems again later.
Pulleys: Pulleys need to spin freely and smoothly. Check all the pulleys for wear, both to the groove where the cable runs and the hole through the center.
Grease: Check grease zircs to see if they need to be refilled.
Bunks: Check the surface of the bunks for excessive wear on the carpeting or splintering of the wood. (ShoreStation UltraBunks are a good replacement where possible.) Worn or splintering bunks can scratch the hull of your boat. Check the bolts to make sure none are loose.
