      I am trying to get my Lofrans Leopard windlass of the deck as I prep the
      boat for painting (and I want to change out the old teak spacer block
      under it.

      I have removed the four stud nuts below deck but the vertical shaft will
      not budge out of the transmission. I noticed a small hole in the side
      of the assembly and wonder if I could run some PB Blaster in there and
      if that would run down the shaft and by and by help free it but I don’t
      want to just instead dilute the tranny grease.

      Anyone had this problem and have a solution?

      Thanks,

      Pete

      Pete,
      I don’t have a Leopard ( have a Royal manual), but since no one else out
      there seems to have one either …

      Looking at the Lofrans drawings (which may not accurately depict your unit),
      I don’t see any nuts on the studs below decks. It looks like the studs
      screw into threads in the below decks gear housing itself. However,
      assuming that means you have freed the studs from the below decks gear
      housing and have removed the drum and the base, all you have is the shaft
      sticking up through the deck and it will not come loose, It appears the
      only items holding the shaft in place are two keys, the lower of which
      appears to engage what they call the wormwheel, but what I would call a ring
      gear.

      So given my description of what you already know (assuming I’m even close to
      accurate), there should be nothing but friction or corrosion holding that
      shaft in place. I understand your reluctance to spray solvent (PBlaster,
      etc.) down the shaft and let it mix with the grease on the worm gear,
      however there may be no better choice. I assume you have to replace the
      grease on the gear every year or so, so what’s the risk? However you can
      always try the standard fine adjustment tool (2 lb mallet) first[?].

      Sorry to not offer anything really usefull. I’ve been looking for a powered
      vertical windlass to replace my manual, horizontal unit, so your question
      just got me looking at the specs on the Leopard. Since I can’t answer your
      question, maybe you can answer a few of mine.

      1. Are you satisfied with the Leopard?
      2. What size anchor and chain to you use with it? I have a 60lb Manson
      on 5/16 proof coil chain.

      John,

      Actually there is a flange which received the four stud ends. The studs
      do not go throrugh the tranny itself. The nuts are easy to get to. The
      whole above-deck assembly should come off as one solid piece with the
      shaft, so nope, I don’t have the above deck assembly off. It is all
      still together. Socket hit by mallet had no effect at freeing the shaft.

      I like a vertical windlass capstan, some prefer horizontal… actually I
      like both. This windlass has never let me down. I have a switch in the
      cockpit which I can operate with my toes and a handheld control forward
      which lets me move around and see exactly what is going on which I
      prefer over deck-mounted foot controls.

      I spoke with a tech at Imtra. Turns out that one can disassemble the
      topside and, sacrificing an oil seal, get down to a pair of circlips to
      release the shaft downward. The motor is then removed with the vertical
      shaft. The oil seals (30x55x10mm) are cheap enough.
