How to Service Bicycle Wheel Bearings

How to Service Bicycle Wheel Bearings

I recommend servicing your hubs once every year. This will however change, depending on how often you ride and what conditions your ride in.

Tools Needed:

1) Rags
2) 15mm Cone Wrench (Rear Hub) - http://amzn.to/AirmTY
3) 13mm Cone Wrench (Front Hub) - http://amzn.to/AirmTY
4) 17mm Open Ended Spanner - http://amzn.to/w8jh26
5) Waterproof Grease and Gun - http://amzn.to/ylMg9M


Bearing Sizes:

Front -- 3/16"
Rear -- 1/4"

Method:

1) Carefully remove any seals protecting the cone and locknut
2) Slide a cone wrench onto the cone flats, the loosen the locknut with the 17mm spanner, by turning it anti-clockwise to the cone wrench
3) Completely un-thread the cone flat and locknut and slide the axel out to the right
4) Clean all the grease off the axel and cones
5) Then remove all of the bearings from both sides
6) Clean both sides of the hub
7) Inspect the cones and inner bearing races for damage, and replace if necessary.
8) Apply generous layer of grease to both of the hus bearing races.
9) Then seat the new bearings in the grease
10) Cover all the bearings in another layer of grease
11) Lightly grease the axel threads, and install the axel through the right hand side of the hub
12) Thread the left side cone flats and lock nut back on finger tight
13) Then tighten fully with cone wrench and spanner.
14) Put the seals back on, and install the wheel back in the bicycle.
15) Check for play in the axel and that it spins smoothly.
16) If there is play, loosen the locknut and tighten the cone flats, then re-tighten the locknut.
17) For quick release axels. Leave a slight bit of play in the hub.

how tight do you screw the nuts (bearing seats) because i tend to over tighten :( to rough arsed lol

@wr10wr36wr60 Hi, you want to tighten the cone just enough so that you can't feel any play in the wheel when its mounted in the bike, but not too much that the wheel doesn't turn. Its a bit of a trial and error process. The locknut however can be tightened a fair amount and will not effect the smoothness of the bearings. Hope this helped. Thanks for Watching!!
