I need help getting the outer ring of a bearing out a trx 3.3

[ANDREW_RC]

I alr tried heating it up and hitting it out n nothing has happened I’m trying to see if y’all have any thing that will help me get them out before I break something

 

[WickedFog]

So the bearing came apart and the outer race is still in the bore?

This sounds like something @STONER RC cound help with.

 

[tntpoof]

try some dry ice.

Wym try dry ice

Lol dry ice. Let me run down to the store to pick up dry ice.
Doesn't even run nitro.

We used dry ice to assemble some aerospace parts we made. You can pick it up at some hardware stores. There were a couple parts that had an interference fit (bore and sleeve machined same size). We used dry ice on the sleeve to slide them into the bore, then bolted them in.

But dry ice would be very tough to use to shrink the bearing race out, because the aluminum engine block would shrink even more than the race does, since aluminum transfers cold and heat much faster than steel does.

So what is there to do then

 

[WickedFog]

Bake the block in an oven. See if that frees up the race.

How long and what temp I put

 

[STONER RC]

Just use a heat gun bud. For a while need a vise to hold the block. Because your going to need it HOT!!! And then a extention with small socket to push it out. What's wrong with the engine that your breaking ot completely down. You could also dry the throwing it in the freezer over night. But heat would probably work better

I think the bearing came apart, and it sounds like all he has in the bore of the block is the outer race.

This guy has all the tricks of bearing removal!..

 

[STONER RC]

Hey I have a old 3.3 block if you would like it bud. I'm me you address. And i will send it to you.. you will just need a new front seal bearing...and the sleeve and piston. Can also send you the crank shaft.. its up to you bud...
