So, how do I get this bearing out?

It's for the shifter cam, which looks kinda like the following, and actuates the dog gears.

Being new to this whole fixing things thing, I don't know many tricks of the trade. Would this be something where I should freeze it? Because it would take a looooooot of effort to convince involved parties to let me put a grimey (note: that is going to be fixed once I get the solvent-averse bearing out) crankcase half in the freezer. Or is there something else that I should do? I think it might come out with a little... persuasion but I really don't want to ruin it because it's really hard to find small parts like that for a 32-year-old engine.

Why do you need to remove it. First question.

So that I can immerse the crankcase in solvents to get it nice and shiny to be reassembled with non-seized pistons.

This is what I would do if I wanted to keep it intact there. Cover the bearing with some tape, not duct tape, to keep any particles from the dirt getting into the bearing. When you have finished cleaning the case in the solvent, put the case in an oven if you can and let a low heat evaporate the solvents that are in the bearing. Or you can just let it air for a few days til the solvents evaporate. Do not use compressed air to try and blow out the solvents. That can damage the bearing. Then take some grease and work it into the bearing afterwards and reassemble.

Torrington style bearings are very hard to remove without damaging and special tools are needed to remove and install.

Thanks much for the advice! What tape would you reccomend that would keep solvent out but isn't duct tape?

Frogtape is pretty good at keeping liquid out.

Personally, I would use a good masking tape, over which you could put a duct tape. The solvent will loosen it but the point is to keep any suspended dirt from getting into the bearing. You could also pack the bearing with rags or something similar. The whole point is to keep dirt from getting into the bearing.

As a side note, Torrington style bearings are designed to be pressed from one side only, so you can't easily remove them without ruining the bearing. Good luck

Head down to Harbor Freight and grab a #1 Tool.

Ha! That was a joke.

Though if there's no lip on the back side of the bearing, find something that fits nicely (like a large socket) over the bearing but inside the hole, and tap it out. The freezer might help a bit as well if it doesn't move with a couple taps.

Actually, scratch that.

Now that I read the whole story, desertdog is right, and you'll probably wreck the bearing (thought you'd be replacing it).

If you're hosing it down in solvent (brushing or spraying), I'd suggest a liberal coating (like globs) of grease, then tape over the hole. Unless you're soaking the case in a tank (and you don't hit the bearing directly with spray or scrubbing) you won't knock the grease loose. At least, not enough to get into the rollers.

I will be soaking it, as the block has 32 years of grime, and it isn't greased, it's oiled because its part of the engine-trans unit. So I think just squirting it hard with oil afterwards will be fine, it's not like it's a high-stress unit or anything, and applying any kind of lubricant other than the oil (10-30 IIRC) can fuck with the wet clutch bigtime. Thanks, though ;)
