A few years back I bought some rear axle bearing sleeves from Mac's. I'm finally getting around to using them on my project, but now know there were inferior sleeves made a few years ago. Is there any way I can tell if the ones I have are the good ones?
How much did you pay for them if it was under 10 bucks, then they are not the good ones, good ones are 18.50 or more now,Bob
What was the problem a few years ago? Cracking, wearing out to quick, wrong size other inferior opportunities for failure. Would a simple file test give you the answer you're looking for?
Oh, I missed the "Macs" reference.
I don't remember what I paid...just ordered some parts from them while I was at Hershey. I was hoping there would be some sort of markings or numbers on them. Looks like I'll have to play it safe and send Bob a check for 4 more new ones.
Good answer David.
Maybe when you get the news ones you'll see if the old ones differ much in their appearance, markings, etc.
Thank you we have them in stock, Bob
I think the difference between the better sleeves and the cheaper ones is their hardness. You should be able to tell whether yours are hardened by trying to cut the outside of them using the corner of a file. That's the "simple file test" Mike G. alluded to. If they're hardened, you should be able to tell it right away. If they're not, the file will easily cut a groove in them.
