Front wheel bearings

[Blair.DRZ]

Was checking the bike over yesterday and noticed the smallest, tiniest bit of play in the front wheel, and from what I have read this means bearings need replacing soon. But was planning on going for a ride tomorrow morning, am i going to bugger it by riding tomorrow, seen as i won't have time to change them before heading out.

i wouldnt think you would do any damage from one more ride

[cheese]

they are really easy to change and cheap to get if you did feel like changing them tonight though.

But yeah I'd put it on the "to do soon" list.

real easy take 1/2 hr knock them out and go to local bearing shop even repco they will be cheap as hate to say it but the bike shops will over harge you what they are worth proberly only a 6304 or 5

speaking of wheel bearings, whats the difference between regular bearings and button bearings? my bike has the latter and the guy i bought it off made sure i knew about them but didnt tell me the differences?
do they need special treatment or something? are they expensive?
googles being un-helpful

while on this subject, whats the best way to get them out? is a bearing remover needed or are there other means?

Nah hamer and punch should be fine take wheel off remove spacers slide punch (old screw drive will do) through from one side you should be able to feel it touch the edge of bearing tap tap out it come same from other side.
To put them in line them up nice and straight i normally use the old ones as a sheild and tap them in till they are seated. Dont!! hit the inner edge where the shaft gose through.

If you have to tap them in - use a brass or aliminum drift.
The better way is to press them in nice and smoothly if you know someone with a press.Apply the pressure on the outer bearing casing always - using a socket or pipe of the same size. This eliminates any damage to bearing race and/or balls. The cooler the bearing the better (heat expands steel - cold shrinks it) SMP Bearings are competitively priced. Best of luck.

Yeh good point should have said put them in the freezer for 10 15 min before you put them in one at a time try not to handle to much as they will warm up quick from your hands.
Same gose if you want to put bearing on a shaft but put it in the oven for 10-15 on round 60 70 deg it will slide straight on on effort at all.

I have 2 bearing catalogs here and there is no mention of button bearings in either of them and Ive never heard of them either.Interesting. You will probably find that they are standard bearings like any other dirt bike.
Did you get a workshop manual with bike? - if so the bearing type and dimension will be listed there.

i did see an add in a mag yesterday going on about Hybrid ceramic bearings
available for steering head and engine kits ment to be less friction = more power according to add which is ture never heard of them before though ???

I've changed most of mine and they have all been standard bearings from my local bearing shop (except the one the third gear rides on). You can download a parts manual from the main gasgas website and it will have a code you can take to your bearing shop.
