Hub cones alright?

edited August 2017 in Workshop
Hi all, I'm new to bike maintenance, and I'm not exactly "mechanically-minded" so forgive the n00b questions. I'm looking to overhaul the hubs on my old bike, do these cones look overly worn or are they alright? Also any recommendations for grease?

    From the photos they look fine. As long as there are no pits or grooves in the bearing track they are good. I just use cheap Marine grease found at Auto supply stores. It resists moisture a little better than most but it's really not all that crucial. Also can be used on bolt threads, bottom brackets, headsets, seatposts, etc. One grease for almost the entire bike. Most greases will work fine for your bearings.

    I've never seen any out-of-the-box so I don't really know what pitted/grooved means in relation to a brand new set. They look grooved to me, but maybe that's how they're supposed to look. I'll see if I can pick up some marine grease then. Cheers!

    Use your fingernail to detect any rough surfaces or uneven surfaces. There is a clear silver line where the balls contact the cones but it does not appear to be a groove. This is normal so should be OK but use the fingernail test or a magnifying glass to be sure.

    Thanks for the tip! I just ran my finger round them and one of them has a small chip in it, does it need replacing?

    Ah, yes that one is damaged. You could still ride on that for a short time if necessary but replace as soon as you can and replace the bearing balls as well. They're cheap and most bike shops will have them in stock.

    Mark the cone with paint at the damage and when you fit the wheel make sure the Pit faces upwards so the balls aren't under load when passing it, I kept a damaged rear cone going for over 1000miles like that when cash was tight.
