I’ll assume that you’re talking about removing the outer race for the tapered roller bearing that is a slip fit on the propshaft.
I do not believe my unit has a tapered roller bearing with a separate race.
I believe the bearing I’m talking about is photo #202 above, that inserts into
the gear housing cover, photo #213.
All three bearings in my lower unit appear to be actual “ball” bearings.
The bearing housing has the “blackest”, messiest grease I’ve ever seen.
Seems like it’s full of carbon, so I’d like to get the bearing out to better
clean it, and the passages in the housing. The bearing seems okay, so
it’s not vital that I have to remove it.
Thanks for the help!Prepare to be boarded!
December 5, 2018 at 11:04 pm #158792If the temperature is below 30, use some rags to hold ice lightly against the bearing. Heat the aluminum housing while it is gasket end down on the bench and the bearing should fall out. Cold makes the aluminum press tighter against the steel, compressing any corrosion. Heat expands the aluminum faster than the bearing and gravity does the rest. – (Hopefully)
December 6, 2018 at 12:21 am #158799Tom, This is what I did on my SpeediTwin and SpeediFour. Should be similar. There is some space behind the bearing that is cut-out. See pictures. I ground a piece of scrap to fit through the bearing and fetch up on the back side. Pulled it out by tightening the nut.

December 6, 2018 at 9:40 am #158826David, thanks for the reply. I’ll have to look again today to make sure
what kind of bearing I’m even working with, and if there’s any
space for a puller to grab on. Thanks!Prepare to be boarded!
December 7, 2018 at 3:51 pm #158931For some reason I’m not able to access the forums from Drop Down List
on the top on the home page. Went under my name and used the
“Topics Started” drop down.
Is it just me having problems?Anyway, I got that pesky ball bearing out of the gear housing today,
heating it up with a hair dryer for a while and slapping the housing
down on the bench. That was the easy part. There’s grease galleys
from the outer housing feeding the long bronze prop bushing.
Old grease was hard to clean out, but mineral spirits, little tiny bottle brush,
and the air compressor finally paid off. I had grease all over my face,
clothes, and garage floor. Snuck in the basement and threw my clothes
in the wash machine…… all by themselves!Prepare to be boarded!
December 7, 2018 at 8:05 pm #158973That black grease is, in my opinion, the best stuff ever made for the old gearcases. I’ve never found a gearcase that had
bad internals when I opened it up and found that grease in there,—-but, it is absolutely the nastiest stuff I’ve ever seen!George
December 8, 2018 at 9:44 am #159607Buc, what kind of bearing did it end up being? 1 or 2 piece?

One piece ball bearing. Will get the number off of it when
I get back to the project.Prepare to be boarded!

December 10, 2018 at 9:10 am #159841Tubs, we may have slightly different “internals”, but I did remember finding a couple
of thin shims by one of the prop shaft bearings, but don’t believe I have the plug and
shims on the end of the prop shaft, like yours.My mother passed away, so the project is on hold for a while.
Will probably have more questions, and will try to document
my parts #’s etc. as I continue on the Elto.
Thanks!Prepare to be boarded!
