Wheel Bearing Removal

(1/2) > >>

Chris400F:
Having picked up a good 350F front wheel for little more than the cost of rechroming my pitted rim I thought I would check the bearings before fitting. The wheel is supposedly from a 10000 mile bike but 40 year old grease possibly not the best.
I picked up a Bearing Retaining Ring removal tool from a very helpful guy on eBay (may give him a plug in the Recommended Sources section) so that bit is out of the way.
Next I need to remove the bearings. Any suggestions for a suitable tool? The Haynes manual suggests a soft metal drift but isn't entirely clear, the Honda Shop Manual stops at removing the retaining ring.
Bearings feel OK but at very least probably want cleaning and greasing, if they are destroyed by removal then new ones will be in order!

totty:
For most bikes you need to tap them out from the opposite side, either pushing the spacer to one side or using a cut out in it. I would always replace after this, and if you're replacing them you don't need to worry about damaging them so anything that fits is a suitable tool. I've never just re greased but I guess to do that you'd leave them in place and just remove the outer seal.

Chris400F:
The bearings are shielded, at least on the side facing outwards.
Sounds like new bearings are probably the best bet - who is a sensibly priced supplier?
I also read somewhere that heating the hub with a hot air gun could help - may try that too.

Bryanj:
Basically take a long rod and push the internal spacer sideways to get the drift onto the inner bearing race and hit the end hard with a large hammer. As you are knocking on the inner race to move the outer race you should ALWAYS replace not re-grease. They are a standard bearing  that should be available from any local supplier or online bike shop but do check the Honda price as way back when it was cheaper to buy Honda at 25% discount than aftermarket with a 75% discount

Chris400F:
Thanks for the advice.
Old bearings now out. A bit reluctant to shift at first but a bit of heat from a hot air gun and they came out with no bother.
New bearings and seals on order from All Balls, should be here tomorrow.
Have already checked out other threads on refitting so should all be sorted this weekend.
