    BEARINGS: Replace or Clean ?

    I have an old DAWES SUPER GALAXY which I would like to refurbish.

    I would like to remove all of the bearings (crank, wheel hub, head) and clean thoroughly and relubricate.

    Since I am going to go that far, would it make sense to just replace ALL of the bearings anyway? I'm assuming they are inexpensive, but I don't even know where to purchase them.

    The bike is probably somewhere around 25-30 years old.

    www.loosescrews.com has loose bearings. You need to know the sizes,and buy the best grade. LBS should have or be able to get too.

    I would inspect the bearings for wear (discoloration or pitting) and replace them if neccessary. Most bike shops can supply loose bearings if they are a common size. Otherwise you'll need to check with an industrial bearing supply.

    I'd replace them, loose bearings are cheap. Make sure that you get the right sizes.

    Another issue that comes up once in awhile on a bike this old is that the bearings wear into kind of a football shape. It's not pronounced enough to see with a naked eye, but you'll never get the old bearings oriented right when you put them back. The result is that it takes the bearings a few miles to reorient themselves. When they do, it causes the hub or whatever to loosen up and you have to readjust the preload again.

    Ok. I think the best route is to buy quality bearings from mailorder. I would suspect that although a LBS might have them, they might not buy the best quality. If I'm going to do this, I'd rather do this right!

    Also, inspect the races and cones for pitting. If they are excessively worn or damaged replacing the bearings will be a waste of money. Depending on the type of hubs they may be replaceable.

    Is grade 200 sufficient, or should I use grade 25 ?

    Also, I'm assuming I will need 3 bags (3 different sizes):

    1 bag for the crank bearings.
    1 bag for both front and rear hubs
    1 bag for the headset

    Does that sound right?

    I'm assuming all of those are different sizes.

    Ball bearings are cheap. Use new ones with each overhaul, and buy the best.

    Grade 25 chromium steel bearings.

    Generally:

    Bottom bracket and rear hub: 1/4 inch bearings

    Front hub: 3/16 (Campy sometimes uses 7/32)

    headset: 5/32 (if you're planning on doing regular overhauls, buy a couple extra bags of these; you go thru them fast, between 50-60 each overhaul).

    Note your bearings may vary, check first.

    Wait a sec...This bike was made in England. Is it possible the bearings are metric (i.e. millimeters) ?

    What is the type of grease that I should use?

    In one of the repair demos I saw on the internet the grease he used was white in color.

    Is it the same grease for the headset as for the bottom bracket and hubs ? Can I put TOO MUCH, or is there no such thing? I don't want to overdo it.

    When I disassemble everything, is it okay to clean it first with something like WD-40 ?

    I like the high-end teflon-based stuff my LBS sells (Finish Line?).

    Use grease liberally. I use the same type of grease for every bearing on the bike, and cables as well.

    Yes, use a good solvent, but be sure to remove it completely before adding new grease, which it will otherwise rapidly degrade. WD-40 is essentially kerosene plus vanilla extract. I have used it for cleaning metal parts and for killing ants. (The last is NOT a joke; ant extermination may be the best use I have found for WD-40. It also works on termites.)

    Everything from white lithium to auto bearing to synthetic waterproof marine works.Wally mart has them all cheap.wd-40 or paint thinner works for cleaning.

    Best thing I've got around the house for cleaning old bearings up is mineral spirits.

    Replace the bearings, they are cheap.

    I have a twenty+ year old bike and repack bearings every spring. I've only had to replace the bottom bracket once, due to broken bearings. I always use new bearings since it's only a couple of bucks. This thing still runs a smooth as new. Use grease from the LBS. The idea is to pack it full of grease and keep the dirt and grit out. I'm a strong recreational rider, and it's rare that the guys (in my age group) with brand new bikes can hang with me. Just like the skiers with all the new stuff.

    Is it because you are AHEAD/FASTER than them, or BEHIND/SLOWER ?

    You're a funny guy. We're talking about beers, right? Really, I've been riding for a while and every one makes fun of my 22 year old Cro Moly Schwinn that I bought new-but I don't have trouble hanging with them.
