What this video covers

Dave services a Lewmar 40 self-tailing winch on Zephyr IV by dismantling the unit, cleaning all internal components, and applying fresh lubrication.Watch He uses a plastic refuse sack to protect the deck from grease and debris during the process.0:33 The disassembly requires no specialized tools, as the top cap, rope diverter, and barrel clips release by hand.0:54 After removing the roller bearings, spacer, and gear assemblies, he cleans all parts in white spirit to remove old, abrasive lubricant.3:30 He uses Harken grease for the gear teeth and bearing surfaces, while applying a light coat of engine oil to the pawls and springs to ensure smooth ratchet operation.6:55 During the service, he discovers hardened grease restricting the self-tailing springs, which he degreases and re-oils to restore movement.9:33 A final test with a winch handle confirms the assembly runs smoothly before he replaces the rope diverter and top cap.9:09 Thorough cleaning of all crevices and gear teeth prevents premature wear from contaminated lubricant.4:21
