Just put my clutch side bearing in. And noticed that one side is not open. I put the closed/retained side into the crank side.
Bearing wrong way round!

Heat the case and pull it back out and reinstall

What saw model??

Stihl 075. I assume the oil needs to lubricate and the retainer although it has gaps should be on te outside to stop dust getting in.
You put the open side out and the metal shield to the crank? Is the crank installed yet or just the bearing in the case? I'd pull the shield, clean the bearing and be done with it. Don't waste your time flipping the bearing since it shouldn't have shields to begin with.
What do you mean by "not open?" Is it a sealed bearing, or is it one of those with the snap on plastic ball cage?

It's not a sealed bearing. As you say it has a plastic cage on one side. Will this just pop,off?

Duh, Snap on ball cage. New bearing required. This time without plastic crap. This was a oem FAG stihl replacement bearing.

Interesting. Are they the original bearings...were you milling?I've had a metal cage fail (original FAG bearing), taking the piston and cylinder with it. I'm not convinced one way or the other.
I now don't know which bearings to get. Not sure about the plastic cages.
Yes, that was the original bearing. Milling? No - it's an 028. I got it free from a friend because of that problem. Pretty sure it was used for firewood, mostly.

All bearings can/will fail. I’ve seen failures from both metal and plastic cages. If metal is available and fits, I go that route due to my installation preferences (heat) and hopes of a longer life. I have no evidence supporting that hope, though.
Was told if plastic fails it causes less carnage inside motor.
Saws I have ,some plastic, some metal.
See how they hold up.

I contacted stihl technical today about these bearings.....apparently they are throng bearings and should be open race.
The authorised dealer sent one with a plastic race and the other sealed grease bearing. Luckily I put it in back to front otherwise I could of had an expensive bang!
Anyway the dealer is sending all the stock back and sending me the right ones asap
