The clutch on my asian 9x20 slips badly on slow speed and not much better on the next speed.
I've dismantled it and all the balls have a definite wear pattern.
The arrows point to a flat spot and a groove on one of the balls.
They also just seem to sit on the holes rather than a small way inside.
The holes in the pulley seem too large for the spring and ball and do show a fair bit of wear on the edge of the holes.
I have seen it said that the holes the balls sit on in the hub should be drill deeper but this would do nothing as the balls do not sit down inside the holes.
I assume they meant drill them to a larger dia as this would then allow the balls to sit deeper to sit deeper.
If I drill them to a wider dia, and use larger balls to fit better in the pulley would this improve things.
Has anybody enlarged and deepened the holes for the balls on this lathe?
