Misc Non-Standard Part supplier reqd.

[JezT]

Hi,

I've searched the web for some 5x7x1mm axle spacers/washers/shims and have only been able to find a Kyosho part (W149) at £4.50 for a pair! For a tiny washer, albeit these are aluminium, I think that is steep. There must be a supplier of small bits out there (not necessarily rc cars) that could supply these cheaper..... Anyone have any contacts?

BTW: it's to fit between the c clip and the back bearing of the front axle of the Mad Rat to stop the binding problem when you tighten the wheel nut.... I know a solution is to tighten then "back off" half a turn but I don't like the wobble this results in.... just wanted to try this solution.

i think the problem is more that you need a tube inside the two bearings like a sort of crush tube so when its tightned up the bearings are not pulled together

Battle-axe,

Thanks for your reply; There is a flange within the front hub that already does that ie grips between the outer bearing on the "back" and "front".... if you pull the "front" bearing out you can see the inner bearing sits free of this. The only component that sits across both inner and outer bearing is the c clip at the back.

Also, the 12mm hex nut has a "spacer" molded into it at the back that only pulls onto the inner bearing, when tightened - it is the equivalent of this that I am trying to source for the other end ie between the c clip and the back bearing.

ok well i think you should give it a go but i have tryed many things and can not sort it out for the life of me i will have another go using this way

Some success - took a brass washer, filed it down to the correct outside diameter and when it sat in the right position it did do the job but.... it wasn't a perfect fit on the inside diameter,so slipped around a bit, wasn't 5mm think it was AF of some similar size.... will try to find some 5mm washer and try again.

Also, think I will have to go the route of aluminium 12mm Hex nuts to firm things up further..... As always, will have to get 2 sets as my son and I both run Mad Rats.... can't do anything on mine and not on his!

The same thing happens on my downhill longboards. If I tighten the wheelnut with no spacers, the bearings get squeezed together and bind.

I have an aluminum spacer between the bearings that only touches the inner race, this permits the wheel nut to be tightened as much as possible without binding.

I also have very small, thin washers that fit between th ewheel nut and bearing on the outside of the wheel, and the same thing between the truck and the wheel. These washers make sure that he only surface of the bearing that is contacted by a stationary surface is the inner race.

Need picks?
