K1 Diff build question

[AdrianJones]

Hi all,

Just bought a K1 today from Steve Webbs Models in Frodsham. I was building the kit and have come across a slight problem. I built both diffs together and one of them is silky smooth and the other is really notchy!

Anyone have any idea what might of caused it. I am worried that the biff balls are faulty straight out of the packet?!

Has this happened before to anyone?

You'll get this feeling if the diff gear is the wrong way round. Take it apart and ensure that the gear is in the correct orientation in relation to the male outdrive. The lip on the gear fits into a groove on the male outdrive.

Hi,

I have tried splitting it all down and cleaning it then rebuilding (many times) to have the exact same result.

Sand the rings and see if it helps....A 600 or 800 grit paper will do.

So, let me get this straight. You want me to sand my ring?

Hi,

Yeh already watched this. Done exactly what he did including the Schumacher bearing blaster (racers best friend). I will have to give the sand paper idea a go!
