    Default Cutlass Bearing

    I'm not finding set screws in my cutlass bearing mounts. Ground off all the paint, even on top. Suppose I need to drill and tap some while they are out? Would there be some other type of retention, don't see anything? Does this mean I should get bearings with straight flutes instead of twisted?

    If they have stayed in place without mechanical fastening, will you be able to get them out?

    Press-fit is fine, but I'd want insurance in the form of set-screws.
    Hope for the best, but plan for the worst.

    Ive never gotten one out without cutting it. Ive seen a cutlass orntwo without set screws. The trick is to polish the inside with crocus cloth and heat the cutlass with a torch, gently....keep the bearing in a ziplock back on ice. When the cutlass is just too hot to touch, slip the bearing in and tap into place with a hardwood block and a dead blow mallet.

    While out of the water, a friend (in)famously slipped into gear. The cutlass melted a bit and then got sucked up the stern tube. There was no way to get at it short of pulling the shaft out, and that was not on because that would entail dropping the rudder. Anyway, didn't seem to bother anything so we put in a new cutlass where it belonged and called that job done. Probably saved some wear and tear on the stuffing box . . ..

    Did it work well for you? Or you are being satirical and you don't think they work.

    edit to add; a sawzall with a long blade is faster

    i'll take either one over "water lubricated hydrodynamic standard rubber sleeve bearing"

    further adding to the confusion is that bf goodrich used to stamp their cutless bearings with a cutlass symbol

    Simpler is better, except when complicated looks really cool.

    If you look around various suppliers' catalogs you can find these bearings called "cutless" and "cutlass" in the same product description. It may be that some of the term "cutlass" becoming more common has to do with autocorrect programs which don't recognize "cutless" as an actual word. I was taught young that it's "cutless" as the bearing won't cut the shaft, which seems a requirement so obvious as to be stupid. In short, neither side of this argument means squat.

    Either way, it is understood and that is what is important!

    Very nice tool, and somewhat expensive, especially with all the various size sleeves you must have. It pays for itself in a boatyard because the shaft does have to be removed.

    Otherwise, remove shaft and cut out with sawzall, or drive old one out with correct diameter piece if it will move. A 'cape' chisel will also help to peel the old cutless.

    You never know what you will run into replacing cutless bearings: set screws, epoxy, original press fit where they must have put the cutless in a freezer and then driven it in. I have had the new cutless fit way too loosely because somebody overbored the strut or stern tube. I really did not want to use epoxy so I had machine shop knurl the outside to pick up enough diameter for a drive fit, and then dimpled for the set screws.

    I have a place that will rent me the tool, $100. Found the set screws. Flathead slotted and four prick punches to lock them in. Not budging so far. Very shallow slots and not exactly in the middle. Odd. Drill out and use a screw extractor?20190316_152919_resized.jpg20190316_152925_resized.jpg

    good luck

    ^Almost what he said. I'd drill them for insertion of an EZ-out tool to remove the screw, then check to see if an Allen-head set screw is available for the existing diameter & thread before committing to drill-out and cutting new threads.
    Hope for the best, but plan for the worst.

    It's a good bet those screws are too short to use an E-Z out...
    If you have that expensive portable press shown, you can just press that Cutless bearing out and worry about the screws later. They will just cut a groove down the side of the old bearing, so what?
    edit; I would probably drill through the screw to remove any "point" that may be into the bearing sleeve, just so the press sleeve doesn't interfere and get "stuck"
