Broken Drive Wheels/ metal core wheel bearing installation

So the other day I was at the park working on my back flips. I just now got no handed back flips down. I was working on doing dub whip flips and such and de-hubbed my rear 110 Drive wheel. The impression I got from the 110 Drive's were the same when I started riding 110 YAK's. They were squrly as hell, but fast as hell.

I also would like to share with everyone MY prime way to install and re-install bearings in metal core wheels. Here is what you do...

Take a pair of old bearings and with a flat head screw driver and a hammer. Do your best into trying to get the outside race of the bearing to detach from the ball bearings and cartridge. It should look like a Finger Ring. Once that is done all you need are some washers and a 5/16" bolt. About 3-4 inches long. Now you have a Bearing Compressor. This new tool will insure that the proper pressure is distributed around the outside ring of the bearing and does not damage the inside ring and ball bearings when you install new bearings in metal core wheels.

When installing the bearings to the wheel the lubricant that I use is WD40. Spray a light coat on the inside of the hub of the metal core wheel. Then, place the bearings on the hub as if you were about to push them into place. Take your new "Bearing Compressor" and stick the bolt through the bearing into the other side of the wheel. Then take the bearing spacer (the little metal tube that goes in between your bearings) and slide it down the bolt as if the bolt was an axle. Then place the other bearing on the other side and tighten the bolt so that the bearings compress simultaneously into the hub of the metal core wheel.

Note: When you are tightening the bolt, make sure the bearings go in straight and not sideways. You can damage your metal core wheels if you compress the bearings at an angle. The bearing is Steal and the hub is AluminumÃ?Æ?Ã?â??Ã?â??Ã?¢Ã?Æ?Ã?¢Ã?¢ââ??¬Ã?¡Ã?â??Ã?¬Ã?Æ?ââ?¬Å¡Ã?â??Ã?¦

When you want to get the bearings out of the hub, simply take a PM/B1 axle, sick it in the bearing and make sure that the bearing spacer between the bearings in the wheel is pushed to the side (when its loose it can move around in between the bearings) The axle should stop and hit the bearing spacer when its pushed to the side. Turn the wheel upside down so that the axle is sticking out of the bottom of the wheel when you hold the wheel flat horizontally. Drop the wheel about a foot above the ground and the bearing should pop right out. Then take that axle and flip it so the Allen Key side (button top) is pushing on the bearing and do the same thing by dropping it on the ground.

That is how I have always done it and it works great. Tell me what you thinkÃ?Æ?Ã?â??Ã?â??Ã?¢Ã?Æ?Ã?¢Ã?¢ââ??¬Ã?¡Ã?â??Ã?¬Ã?Æ?ââ?¬Å¡Ã?â??Ã?¦

Putting them in sounds good but no matter what taking bearings out damages them. If you are pounding them out by the inner race like you described that means the actual balls are bearing all the weight of the impact. If you are just taking them out to throw them away and put new bearings in then that's fine but I wouldn't reuse the bearings after that. (not that you couldn't reuse them... they would still work just not as well.)

I dont know what you guys aretalking about.
I have drive wheels and reds bearings and I held the bearings level and they slid in by finger power.
All I did was just slide them in with my pointer finger.
Looks like I got a lucky pair.

The problem I found with aluminum core wheels is the Aluminum is softer then the steal bearing. So its not even worth using them because they ware house and get loose. Ive ridin my front drive and its already getting loose

well done man,
only thing I wanted to ad:
it's easier to gett the balls off the bearing:
use a little screwdriver whith that profile - , don't know the english word but I hope you know what I mean. then press it between the cap and the ring you want to use for your wheel. just pull it to the side. first you'll just bend the cap, but after doing this for 2-4 times you should get it off easily. if you opened you 'ss se a ring which holds the balls in their position. If you have Oil bearings the ring is made out of plastic and you have to open the cap of the otherside and just can clips it off the balls if you push from the right side. If you have a grease Bearing the ring is made out of two rings one oon each side, which holdes the Balls in position. and on one side you'll see little "clips" which hods the rings together. If you bend all of them up you should get off the ring and the balls will fall out of the bearing...

...All in all i don't see any sence by the use of alu wheels, cause they are not better than the yaks, as I know...
Mayby somebody should make them out of steal... makes more sence...

no it doesnt make sense aluminum wheels are already heavy enough as it is
and I dont see why everybody has problems with drives
theyre so goood nothing ever happened to mine
and for wearing them in to make them harder just stand on a tredmill for a couple of hous
a couple of days ago it was rainy so I ate dinner riding no handed on my scooter on the treadmill haha
