[Alberg30] Cutlass bearing removal

[Mike Lehman]

Hi Bob,

It would help to know what hull #/year of your boat. On my boat #505/1972 
the cutlass bearing housing is screwed onto the stern tube. There are two 
bolts into the keel on the cutlass bearing housing. Remove the two bolts and 
unscrew the complete housing from the stern tube. Now that you have the 
housing with old cutlass bearing inside, you can place it in a vise and 
using a hacksaw blade carefully cut sections out of the cutlass bearing. 
Once you have removed a section or two you should be able to remove the 
entire cutlass bearing from the housing. Then work on removing the screws. 
Heat might help. You may eventually end up drilling out and re-tapping the 
set screws. Replacement set screws should be SS allen screws. Install the 
new cutlass bearing; cut it to proper length; and drill water vent holes 
through the bearing where the water inlets are in the housing. Put in new 
set screws and re-install the housing with new bearing back on the boat. The 
good thing about removing the housing is that if you do not possess the 
skills or tools, you can take it to a machine shop.

I just pulled the shaft to replace stuffing box hose and to inspect
condition of shaft condition.
I would like to replace the cutlass bearing as well.

There are two set screws on the outside of the stern post flange that
hold the cutlass bearing in place.

These set screws have a slot for screwdriver removal.

I cannot remove these screws in order to remove the cutlass bearing.

They appear to be seized.

(Q1) Do I need heat or an impact tool to remove these screws?

I'm afraid of snapping the head off these set screws.

(Q2) Is the stern tube that fastens to stuffing box hose also fastened
to sternpost flange?



Any advice would be appreciated.
