spacers

[gee2626 0]

i have use the labeda hum'er chassis which has the axle fit to the bearing hole, rather than having the spacer fit the axle/screw system. you're suppose to put the short spacers in between the bearings, however it seems pointless for me to put them in... they don't do much but add weight.

is there another purpose for the spacers?? do i really need to put them it???

thanks

Pretty sure you do. I tried it once just because I was bored, and it diddnt seem to spin right. Maybe it was just me.........................

I've never put the spacers in when I changed wheels and theirs always been alot of clanking, since I started to put them in (on my Hi-Ho's and Sensors) it seems to have allievated this problem.

without spacers, if you tighten the axle all the way, the wheel will get stuck and not spin at all...

that happens to me anyways, even with spacers... i just don't tighten the axles too hard

if you dont have spacers the wheels will shake

mine don't shake..... you might be thinking if i didn't have the conventional spacers, ie the longer ones

Ok ..one more time..here's how it works....

The axle spacers are there to allow the inner race of the bearings and the boss located on the inside of the chassis to become a "one piece support" when the axle bolt is tightened. When you do this, the inner edge of the bearing inner races are pulled tight against the "floating spacer" as used in the Hum'er and other chassis assemblies, and the outer edges of the inner races are pulled tight against the frame bosses.

The outer race of the bearing should be just touching the edge of the lip inside the wheel hub when all is tightened up, or, have a couple of thousandths play. This is what you feel when you "click" the bearings by pushing the wheels back and forth once tightened.

If the wheels will not "click" and spin freely, then the most likely problem is that the little ridge (inner hub flange) inside the wheel hub, is wider than the spacer. When this happens and you tighten the wheel normally, the bearing will bind up, because the outer race of the bearing is now tight against this lip, before the inner race is tight against the spacer.....got it?

This problem is common to many manufacturers at times, as whoever makes the hub molding for their wheels seems to get the tolerance messed up on this inner lip quite frequently....

So the answer is "yes" you do need the spacers..without it the bearings have no chance of spinning freely, if you tighten the wheels normally. As soon as the wheel is pushed sideways while under skating load, it wil begin to bind up without a spacer, even if you leave the axle bolt loose. If you are using the right kind of spacer for your wheels, and the wheel is still binding, and you cannot "click it" back and forth, then the problem is usually in the wheel hub tolerance....If you can "click it", and the wheels are still binding when tightened, then it is because the shoulders inside the hub are not perfectly parellel, and when you tighten, the bearings get "cocked" slightly.....this may go away after afew uses.

There are some other problems with particular chassis' but they are more rare.
