Author Topic:   Serious problems removing the prop shaft bearing housing

In assisting my local shop replace the clutch dog in my 1987 40HP Johnson, I'm trying to find the secret trick in removing the prop shaft bearing housing. Despite having heated the gearcase and breaking 2 wheel pullers already, it's just not budging. I don't think it has never been removed before and aluminum oxide must be working its magic. If anyone could come up with a bottle of something that dissolves the stuff, they'd make themselves a pretty penny.

Any suggestions?

I know how to remove it in less than 15 minutes but I am not telling. Well, maybe if you are sworn to secrecy. Steve

I won't tell....I used to be called "Secret Keeper" before I was HAPPYJIM.
I'll trade where Jimmy Hoffa is for the prop shaft bearing secret.

Went through that with a SPL48 and ended up buyying a rebuilt lowwer unit. Two shops could not get the bearings out.

Good Luck

I'm not even sure what the bearing looks like that you are trying to pull so this may not work. Buy a couple of cans of freeze spray at an electronics store and cool the shaft as you heat the bearing.

It took a little jerry-rigging of a number of tools to do the trick, but it's finally out. Thus, no need for me to swear to god, allah, the dhali lama, etc. about all these secrets.

So, where is Hoffa? I have developed a simple tool that will take just about any salted-in frozen bearing carrier free from its housing. Without breaking the carrier or housing, of course. Outboard or I/O. I have two proto-types and the tool is blue-printed. Just waiting on a patent search and its all yours. Where are all the investment capitolists when you really need them.... Steve
