B2/B3 CVD Axle Spacing Problem

[DerbyDan]

So, I fitted the MIP B2/B3 CVDs combined with 3/16" x 3/8" Avid bearings so I can run later 2.2" B3 wheels. I filed down some Losi axle spacers so that they were a nice fit between the roll pin & the bearing..... but on one run of the car I noticed one wheel was binding up causing the car to veer to one side.

On investigation it seems the roll-pin sits deeper into the wheel - which mean't that as I tightened up the wheel I was crushing the bearings - on running the car its enough to have caused them to get hot & collapse.

My queiry is to ask what do people do to ensure you don't crush the bearings? .... is there a kit (like what was available for the Losi XX) that includes a spacer to fit between the bearings inside the hub?

Thanks

Dan

Have you tried it with out the losi spacer?

get rid of the losi spacer. mine is set up with no shims on the inside and 2 thin shims on the outside. get it so it tightens down on the axle pin and then add shims till you get the right amount of play.

I use B4 axles and run the B4 outside spacer, it helps add a little width to the rear end

Thanks Mark for those links.... something to consider for sure

The Losi spacer I have fitted on the outside (between outer bearing & roll-pin) But I did have to 'thin' them down.... firstly it was to a 'perfect' fit.... I have now thinned them down a bit more so that when the wheel is fully tightened there still is a little bit of play - so we'll see how it goes once my replacement bearings have arrived

BTW There's no spacer fitted between the bearings inside the hub.
