what size is bore size an od

Hello and thank you for your interest in the LFW137 flywheel by LuK. If I understand correctly you're asking for the ID where the pilot goes and the OD of the total flywheel? If so the ID for the pilot is 1.261 and the overall OD is 11.272 at the tip of the ring gear teeth.

What does " refer to Lb 194" regarding the slave release bearing mean??

I have no idea, I suggest you contact the seller.

Will this fit my 2002 6 cylinder 3.0 ranger?

No this flywheel fits 2.3 or 2.5 L Ford Ranger.

Will this fit 1991 manual Chevrolet 2500 350

I doubt it. I got it for a ford ranger with a 2.3 4 cyl
