XRAY - Model racing cars

There is no gap between the bearing and the bolt. The instructions distance from the nut to the end of the shaft 11-11,2 mm. With the new flywheel distance of less than 10 mm (((

I'm sorry for my bad english.

The flywheel is fully tightened. Installed three different cone.
This problem is not just me. The other two XB9 2013 with other engines too, there is no gap

How much space is between the flywheel and the front of the engine case? There should only be about half a mm.

Some hobby shops have crankshaft extensions.

It's the same for O.S. too. You can either use the OFNA or Losi crank shaft extension/washer and then you will have plenty of room to shim how you need to.

Try a Durango dnx408 13T bell, I've run the same bell on an 808 and xb9 and now on a xb9 13(using an xray brass collet too)... overall height of the xray is 21.50mm, the Durango is 21.03, and they last longer than the xray ones. the only good thing Durango made.......
It's on an O.S XZ-B 21 Speed....also if your tired of using cable ties on the air cleaner tube base, try the O-ring from the O.S Super Air Filter kit, works well and you can pick up the car by the air cleaner and it wont come off, to remove just roll up the O-ring and remove the a/c assembly.

Thanks for the tips! I'll try.
I returned from the three-day competition. Driving without a gap, bearings changed once. Breakdowns were not.

If I'm not mistaken, the Novarossi BTT's front bearing has a 6,3mm wide inner race compared to other normal bearings that is 6,0 mm

All that is needed is a losi 8ight collet and the problem will be fixed. I just put together my 2013 and used the losi collet and everything fits perfect
