Advice on removing a bearing carriage please


FOOTDOC

Question

I have a 91 johnson outboard and am having difficulty removing the bearing carriage to rebuild the lower unit. I have tried a bearing puller, a slide hammer and soaking in a solvent. Any suggestions? Thanks in advance!

I might not be understanding you or your situation, but...it must be somewhat mobile/ out of the lower unit. Try heating it up in oil (I have used a "fry Daddy" type unit to get bearings off of crank shafts (like motor oil or the like)), causing it to expand and should be able to remove more easily.

The "Fry Daddy" could never be used for food again, just for the shop.

I have mostly used this method to preheat bearings to put onto the shafts. Be creative.

Another idea along the same line, try heating the outer with a heat gun or a propane torch - it expands more allowing disassembly of close or slight interference fit parts. SAFETY FIRST - it needs to be clean enough of lubricant to not catch fire while working if you use a torch. I don't recommend a 'cutting torch', etc: too hot to control easily. This trick works with a lot of press-fit parts.

      As crazy as that might sound, May 18th isn’t a bad guess.  We were on the lake yesterday and had somewhere around 30” of solid ice with some snow on top.  This is hard January-type ice.  No honeycombing, no chipping or slush.  In fact, my Dewalt hammer drill couldn’t take it.  It’s dead.   Another foot of snow on the way this week?  That won’t help.

      Try the area where Minnehaha Falls runs into the river up to the ford dam. I've just used jig and fathead. Been several years since I've fished down there, but saw a lot of people shore fishing there. Pretty snaggy down there.

      Never tried it down there, sounds like fun. Let us know how you did.  👍

      Entries sure rolled in when I offered the case of beer.  We could meet at my Stuntz Bay boathouse if that would work.  Close to the landing, could anchor in front of the boathouse, or could park your vehicle at by the boathouse.  Maybe we could require the winner to be present, LOL.

      Thinking about trying pool 2 (from shore) for the first time tomorrow morning, ideally looking for walleye. Anyone know any decent spots or what kind of baits I should use?   Thanks in advance

      I know the owner.  In fact we rode snowmobiles together a couple days after the fire.  He lost most of his belongings.  Sounds like it was electrical.
