Cutlass bearing question

[erps]

Thanks Int14. I think the software here requires a minimum number of posts before it lets you attach pictures, so you picture didn't show up. If the cutlass is installed in epoxy or grp, what is recommended to seal the new one in when the old one is removed?

Working with bearings, one approach you could look at is to get one of the new marine composite bearings, these can be fitted as a clearance fit which means that with the shaft chocked th ebearing should spin in the carrier and on the shaft. Once this is achieved the bearing is bedded on epoxy.

For grp stern tubes you can put release agent on the bearing, you can then split the bond easily when you want to remove the bearing. These are now used on Lloyds class ships so it is proven technology. The solid composite bearings offer closer tolerance shaft support whch can reduced shaft whip and vibration. For metal struts/P brackets you just heat the metal and the old bearing will slide out as the epoxy softens.

I always put the cutlass bearing in a stainless steel bowl of salt water, then in the freezer over night. Freezing the bearing in dry ice would also work, but I have found frozen bearing in the bottom of a deep freeze in salt water works every time so far. Have your threaded rod, and helper to hold wrench inside boat, work fast, and draw the new bearing into it's race.
