[AT] Farmall A bearing noise

[joehardy]

Just finished cutting my lawn with my "A", took off my ear muffs and heard a knocking sound. The engine had no major work done on it since being built. Where can I buy a book on rebuilding a gas engine with sleeves? I have a good guy to work with me on some of the other work but no experience with replacing sleeves. I know, from time to time, hints have been posted on this site. Thanks for any help you can give!
