The front wheel bearings were also replaced, but that was on another wheel that wound up snapping a spoke.
Rather than spend the $$ on new spokes, and the time re-lacing them; I opted to take the lazy route and replace the bearings in the original wheel from his K3. It's funny how this wheel was previously not used because I wanted to avoid doing a bearing swap in the first place.
On the upside, this tire has more tread left that the one on the other wheel.
|All the parts required.|
|Old bearings were already pressed out.|
|Notice the different part numbers?|
Bearing on left is a U meaning it's sealed on one side.
The one on right is a UU meaning it's completely sealed.
The stock bearings were single side sealed but having
a fully sealed one in there won't hurt anything.
|Place bearing to be set.|
|Cover with old bearing to drive new one in evenly.|
|Cover with rubber maillot and smack with a BFH.|
|Place oil seal.|
|Place bearing retainer ring and use a spanner or |
a screwdriver/chisel+hammer to drive it in.
I actually used a file to turn it most of the way in, then finished
driving it in with a flat-head screwdriver and maillot.
|Eventually it'll look something like this.|
It's easier to set the bearing retainer first then drive in the oil seal.
Or set the oil seal in the retainer then drive it in like I did.
|Place the axle collar (use grease to keep it there).|
|Place bearing. This is the "U" (one side sealed) bearing.|
Note the unsealed side is facing IN the wheel.
|Place the seal o-ring over the hub.|
Slide on the assembled speedo drive and slide axle through.
Sorry for lack of assembly pics here, the process was a bit too
greasy to be touching my camera in between steps.
|Screw on the axle nut to the other side.|
|Slide on brake disc and bolts. and you're all set!|
Most of the bad things happen in the bearing removal process;
particularly with getting the old bearing retainer out.
Next time I do this I'll be making one of these:
