The loads on winches are substantial indeed. Add to that a regular dousing with seawater and you have machinery that, if not routinely serviced, is prone to premature failure. The good news: Manual single-speed winch service is an easily undertaken maintenance project, and such work on multispeed winches is only slightly more complex. Parts and pieces are typically very simple. Note, however, that winch parts, while uncomplicated in nature, can be easily dropped or lost in a marine environment.
