Does anyone know what material the Tides bearings are
made from?
yes
Attached is bearing drawing
Rudder Bearing Replacement -- Labor to: measure rudder
tube, bearings, rudder shaft, send information to
bearing manufacturer and owner. Order two new bearings
and one thrust bearing washer. Prep interior surface
of rudder tube in worn areas, then apply 3 coats of
Pettit Protect (2 part epoxy paint) to make rudder
tube smaller and fit new bearing snug. Fill/ fair
bottom edge of bearing flange for smooth finish
surface. Install new bearings with thickened epoxy
(from bottom and top), and fit rudder shaft into
place. Align Rudder with trailing edge of keel prior
to epoxy hardening. Reassemble rudder quadrant and
tension steering cables.
16.5 hr @ $55.00?? $907.50
Color Restoring & Waxing Hull -- Labor to: tape
off bottom paint, and preform an efficient process of
applying compound and power buff/ wax topsides of the
hull. Hand wipe to remove excess wax and remove tape.?
7.25 hr @ $53.00?? $384.25

1. My yard epoxied the bearings in but I share
Roger's concern about if they ever have to come
out again.? Except, at my age for better or worse,
not likely my problem.? Sailing in deep Maine
waters, not a lot of sediment get kicked up.? Yard
said they were installed with a parsimonious
amount of 5200.? The bottom one had come loose
(crossing Gulf of Maine to Nova Scotia of course),
that's what alerted me to problem.
I believe my boat spent some of its early life in
dirty water (
. . .. .oh Boston your my home).?
Damage photo below.
2. I would check with Tides on the fit.? Mine were
not tight.

Barry,
?
Attached are the specs for the bearing.? I
got this from Glen Chaplin at Sabre.? The photos
I referred to are the ones Dave Short sent.? As
you saw in Dave's photos, the lower bearing is
mounted flush with the hull, and was epoxied
in.? Tides Marine, who made my bearings (and I
believe also made the originals) also said to
epoxy them in.? However, my original ones were
installed with 5200, which is what Glen also
said for the replacements.? My inclination is to
use 5200, as once epoxied I don't think they
could be removed without damage to the hull
tube.?
?
As noted in my prior post on the topic, I am
having an issue with the bearings being really
tight on the rudder post.? Yesterday I sanded
the rudder post to ensure it was perfectly
smooth, and although I could get the bearings on
by warming them slightly, once they cooled to
the ambient temp (mid 40s here on the MA south
coast) they became so tight I could not turn
them by hand.? I'm still trying to figure out
what to do.
