Best way to rebuild a 105 rear hub?(3 posts)

Best way to rebuild a 105 rear hub?cabinfever
Oct 12, 2002 10:07 AM
I have an old, heavy rear wheel that I want to use on my bike this winter while it's on the trainer so I don't put excess wear on my Race X Lites. I basically need all new internal parts for Shimano 105 hub (axle, cones, seals, some ball bearings, etc). What is the best way to do this? Any online stores that I can purchase these items from? I do have the cone wrenches I should need.
...throw it out and buy a Campagnolo rear hub...Spunout

Okay, maybe not;-)

Do you know that you need an axle? Cones? If the cones are polished without being pitted, they're still okay. Actually, well used is better than new as they might actually improve. Same with your bearings, if they are all smooth, then they are better than new. I'm speaking from a Campy perspective, I don't know if Shi*mano components last that long.

You could take it apart first, look it over, roll the axle to make sure it is straight, take a cone and a few bearings in to your LBS to make sure.

Wash the hub out, lotsa grease, and put it all back together in the reverse order that you took it apart. EASY!!!!

BTW, your race X-lites can handle what you throw at them if they're worth their salt.

.....check your cups AND cones for pits. If none, don't replace. I would suggest however that you replace your bearings. They're cheap and easy to get. Your LBS should stock them. If not, or no LBS handy, a bearing house (found in the yellow pages under bearings) will have the bearings. Buy grade 25, a little more expensive but much better. Don't cheap out on bearings. Make note of the number of bearings on each side of the hub. When you put the correct number in, it looks like you can put in one more. Don't! You don't need new axles unless bent.

Go to the Parks Tools repair help site for the section of Hub Bearing Overhaul and Adjustment. A wealth of info. Good luck and have fun!
